+### Addendum (2026-02-17): Provider-scoped hook state and default source IDs
+
+This addendum introduces a **breaking change** that supersedes earlier references in this ADR where hooks received the
+entire `session.state` object as their `state` parameter.
+
+#### Hook state contract
+
+- `before_run` and `after_run` now receive a **provider-scoped** mutable state dict.
+- The framework passes `session.state.setdefault(provider.source_id, {})` to hook `state`.
+- Cross-provider/global inspection remains available through `session.state` on `AgentSession`.
+
+#### Session requirement and fallback behavior
+
+- Provider hooks must use session-backed scoped state; there is no ad-hoc `{}` fallback state.
+- If providers run without a caller-supplied session, the framework creates an internal run-scoped `AgentSession` and
+  passes provider-scoped state from that session.
+
+#### Migration guidance
+
+Migrate provider implementations and samples from nested access to scoped access:
+
+- `state[self.source_id]["key"]` → `state["key"]`
+- `state.setdefault(self.source_id, {})["key"]` → `state["key"]`
+
+#### DEFAULT_SOURCE_ID standardization
+
+Aligned with and extending [PR #3944](https://github.com/microsoft/agent-framework/pull/3944), all built-in/connector
+providers in this surface now define a `DEFAULT_SOURCE_ID` and allow constructor override via `source_id`.
+
+Naming convention:
+
+- snake_case
+- close to the provider class name
+- history providers may use `*_memory` where differentiation is useful
+
+Defaults introduced by this change:
+
+- `InMemoryHistoryProvider.DEFAULT_SOURCE_ID = "in_memory"`
+- `Mem0ContextProvider.DEFAULT_SOURCE_ID = "mem0"`
+- `RedisContextProvider.DEFAULT_SOURCE_ID = "redis"`

+# Structured Output
+
+Structured output is a valuable aspect of any agent system, since it forces an agent to produce output in a required format that may include required fields.
+This allows easily turning unstructured data into structured data using a general-purpose language model.
+
+## Context and Problem Statement
+
+Structured output is currently supported only by `ChatClientAgent` and can be configured in two ways:
+
+**Approach 1: ResponseFormat + Deserialize**
+
+Specify the SO type schema via the `ChatClientAgent{Run}Options.ChatOptions.ResponseFormat` property at agent creation or invocation time, then use `JsonSerializer.Deserialize<T>` to extract the structured data from the response text.
+
+	```csharp
+	// SO type can be provided at agent creation time
+	ChatClientAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions()
+	{
+		Name = "...",
+		ChatOptions = new() { ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>() }
+	});
+
+	AgentResponse response = await agent.RunAsync("...");
+
+	PersonInfo personInfo = response.Deserialize<PersonInfo>(JsonSerializerOptions.Web);
+
+	Console.WriteLine($"Name: {personInfo.Name}");
+	Console.WriteLine($"Age: {personInfo.Age}");
+	Console.WriteLine($"Occupation: {personInfo.Occupation}");
+
+	// Alternatively, SO type can be provided at agent invocation time
+	response = await agent.RunAsync("...", new ChatClientAgentRunOptions()
+	{
+		ChatOptions = new() { ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>() }
+	});
+
+	personInfo = response.Deserialize<PersonInfo>(JsonSerializerOptions.Web);
+
+	Console.WriteLine($"Name: {personInfo.Name}");
+	Console.WriteLine($"Age: {personInfo.Age}");
+	Console.WriteLine($"Occupation: {personInfo.Occupation}");
+	```
+
+**Approach 2: Generic RunAsync<T>**
+
+Supply the SO type as a generic parameter to `RunAsync<T>` and access the parsed result directly via the `Result` property.
+
+	```csharp
+	ChatClientAgent agent = ...;
+	
+	AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("...");
+
+	Console.WriteLine($"Name: {response.Result.Name}");
+	Console.WriteLine($"Age: {response.Result.Age}");
+	Console.WriteLine($"Occupation: {response.Result.Occupation}");
+	```
+	Note: `RunAsync<T>` is an instance method of `ChatClientAgent` and not part of the `AIAgent` base class since not all agents support structured output.
+
+Approach 1 is perceived as cumbersome by the community, as it requires additional effort when using primitive or collection types - the SO schema may need to be wrapped in an artificial JSON object. Otherwise, the caller will encounter an error like _Invalid schema for response_format 'Movie': schema must be a JSON Schema of 'type: "object"', got 'type: "array"'_. 
+This occurs because OpenAI and compatible APIs require a JSON object as the root schema.
+
+Approach 1 is also necessary in scenarios where (a) agents can only be configured with SO at creation time (such as with `AIProjectClient`), (b) the SO type is not known at compile time, or (c) the JSON schema is represented as text (for declarative agents) or as a `JsonElement`.
+
+Approach 2 is more convenient and works seamlessly with primitives and collections. However, it requires the SO type to be known at compile time, making it less flexible.
+
+Additionally, since the `RunAsync<T>` methods are instance methods of `ChatClientAgent` and are not part of the `AIAgent` base class, applying decorators like `OpenTelemetryAgent` on top of `ChatClientAgent` prevents users from accessing `RunAsync<T>`, meaning structured output is not available with decorated agents.
+
+Given the different scenarios above in which structured output can be used, there is no one-size-fits-all solution. Each approach has its own advantages and limitations,
+and the two can complement each other to provide a comprehensive structured output experience across various use cases.
+
+## Approaches Overview
+
+1. SO usage via `ResponseFormat` property
+2. SO usage via `RunAsync<T>` generic method
+
+## 1. SO usage via `ResponseFormat` property
+
+This approach should be used in the following scenarios:
+ - 1.1 SO result as text is sufficient as is, and deserialization is not required
+ - 1.2 SO for inter-agent collaboration
+ - 1.3 SO can only be configured at agent creation time (such as with `AIProjectClient`)
+ - 1.4 SO type is not known at compile time and represented by System.Type
+ - 1.5 SO is represented by JSON schema and there's no corresponding .NET type either at compile time or at runtime
+ - 1.6 SO in streaming scenarios, where the SO response is produced in parts
+
+**Note: Primitives and arrays are not supported by this approach.**
+
+When a caller provides a schema via `ResponseFormat`, they are explicitly telling the framework what schema to use. The framework passes that schema through as-is and
+is not responsible for transforming it. Because the framework does not own the schema, it cannot wrap primitives or arrays into a JSON object to satisfy API requirements,
+nor can it unwrap the response afterward - the caller controls the schema and is responsible for ensuring it is compatible with the underlying API.
+
+This is in contrast to the `RunAsync<T>` approach (section 2), where the caller provides a type `T` and says "make it work." In that case, the caller does not
+dictate the schema - the framework infers the schema from `T`, owns the end-to-end pipeline (schema generation, API invocation, and deserialization), and can
+therefore wrap and unwrap primitives and arrays transparently.
+
+Additionally, in streaming scenarios (1.6), the framework cannot reliably unwrap a response it did not wrap, since it has no way of knowing whether the caller wrapped the schema.Wrapping and unwrapping can only be done safely when the framework owns the entire lifecycle - from schema creation through deserialization — which is only the case with `RunAsync<T>`.
+
+If a caller needs to work with primitives or arrays via the `ResponseFormat` approach, they can easily create a wrapper type around them:
+
+```csharp
+public class MovieListWrapper
+{
+    public List<string> Movies { get; set; }
+}
+```
+
+### 1.1 SO result as text is sufficient as is, and deserialization is not required
+
+In this scenario, the caller only needs the raw JSON text returned by the model and does not need to deserialize it into a .NET type.
+The SO schema is specified via `ResponseFormat` at agent creation or invocation time, and the response text is consumed directly from the `AgentResponse`.
+
+```csharp
+AIAgent agent = chatClient.AsAIAgent();
+
+AgentRunOptions runOptions = new()
+{
+        ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>()
+};
+
+AgentResponse response = await agent.RunAsync("...", options: runOptions);
+
+Console.WriteLine(response.Text);
+```
+
+### 1.2 SO for inter-agent collaboration
+
+This scenario assumes a multi-agent setup where agents collaborate by passing messages to each other.
+One agent produces structured output as text that is then passed directly as input to the next agent, without intermediate deserialization.
+
+```csharp
+// First agent extracts structured data from unstructured input
+AIAgent extractionAgent = chatClient.AsAIAgent(new ChatClientAgentOptions()
+{
+    Name = "ExtractionAgent",
+    ChatOptions = new() 
+    { 
+        Instructions = "Extract person information from the provided text.",
+        ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>() 
+    }
+});
+
+AgentResponse extractionResponse = await extractionAgent.RunAsync("John Smith is a 35-year-old software engineer.");
+
+// Pass the message with structured output text directly to the next agent
+ChatMessage soMessage = extractionResponse.Messages.Last();
+
+AIAgent summaryAgent = chatClient.AsAIAgent(new ChatClientAgentOptions()
+{
+    Name = "SummaryAgent",
+    ChatOptions = new() { Instructions = "Given the following structured person data, write a short professional bio." }
+});
+
+AgentResponse summaryResponse = await summaryAgent.RunAsync(soMessage);
+
+Console.WriteLine(summaryResponse);
+```
+
+### 1.3 SO configured at agent creation time
+
+In this scenario, the SO schema can only be configured at agent creation time (such as with `AIProjectClient`) and cannot be changed on a per-run basis.
+The caller specifies the `ResponseFormat` when creating the agent, and all subsequent invocations use the same schema.
+
+```csharp
+AIProjectClient client = ...;
+
+AIAgent agent = await client.CreateAIAgentAsync(model: "<model>", new ChatClientAgentOptions()
+{
+    Name = "...",
+    ChatOptions = new() { ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>() }
+});
+
+AgentResponse response = await agent.RunAsync("Please provide information about John Smith.");
+
+PersonInfo personInfo = JsonSerializer.Deserialize<PersonInfo>(response.Text, JsonSerializerOptions.Web)!;
+
+Console.WriteLine($"Name: {personInfo.Name}");
+Console.WriteLine($"Age: {personInfo.Age}");
+Console.WriteLine($"Occupation: {personInfo.Occupation}");
+```
+
+### 1.4 SO type not known at compile time and represented by System.Type
+
+In this scenario, the SO type is not known at compile time and is provided as a `System.Type` at runtime. This is useful for dynamic scenarios where the schema is determined programmatically, 
+such as when building tooling or frameworks that work with user-defined types.
+
+```csharp
+Type soType = GetStructuredOutputTypeFromConfiguration(); // e.g., typeof(PersonInfo)
+
+ChatResponseFormat responseFormat = ChatResponseFormat.ForJsonSchema(soType);
+
+AgentResponse response = await agent.RunAsync("...", new ChatClientAgentRunOptions()
+{
+    ChatOptions = new() { ResponseFormat = responseFormat }
+});
+
+PersonInfo personInfo = (PersonInfo)JsonSerializer.Deserialize(response.Text, soType, JsonSerializerOptions.Web)!;
+```
+
+### 1.5 SO represented by JSON schema with no corresponding .NET type
+
+In this scenario, the SO schema is represented as raw JSON schema text or a `JsonElement`, and there is no corresponding .NET type available at compile time or runtime.
+This is typical for declarative agents or scenarios where schemas are loaded from external configuration.
+
+```csharp
+// JSON schema provided as a string, e.g., loaded from a configuration file
+string jsonSchema = """
+{
+    "type": "object",
+    "properties": {
+        "name": { "type": "string" },
+        "age": { "type": "integer" },
+        "occupation": { "type": "string" }
+    },
+    "required": ["name", "age", "occupation"]
+}
+""";
+
+ChatResponseFormat responseFormat = ChatResponseFormat.ForJsonSchema(
+    jsonSchemaName: "PersonInfo",
+    jsonSchema: BinaryData.FromString(jsonSchema));
+
+AgentResponse response = await agent.RunAsync("...", new ChatClientAgentRunOptions()
+{
+    ChatOptions = new() { ResponseFormat = responseFormat }
+});
+
+// Consume the SO result as text since there's no .NET type to deserialize into
+Console.WriteLine(response.Text);
+```
+
+### 1.6 SO in streaming scenarios
+
+In this scenario, the SO response is produced incrementally in parts via streaming. The caller specifies the `ResponseFormat` and consumes the response chunks as they arrive.
+Deserialization is performed after all chunks have been received.
+
+```csharp
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions()
+{
+    Name = "HelpfulAssistant",
+    ChatOptions = new()
+    {
+        Instructions = "You are a helpful assistant.",
+        ResponseFormat = ChatResponseFormat.ForJsonSchema<PersonInfo>()
+    }
+});
+
+IAsyncEnumerable<AgentResponseUpdate> updates = agent.RunStreamingAsync("Please provide information about John Smith, who is a 35-year-old software engineer.");
+
+AgentResponse response = await updates.ToAgentResponseAsync();
+
+// Deserialize the complete SO result after streaming is finished
+PersonInfo personInfo = JsonSerializer.Deserialize<PersonInfo>(response.Text)!;
+```
+
+## 2. SO usage via `RunAsync<T>` generic method
+
+This approach provides a convenient way to work with structured output on a per-run basis when the target type is known at compile time and a typed instance of the result
+is required.
+
+### Decision Drivers
+
+1. Support arrays and primitives as SO types
+2. Support complex types as SO types
+3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
+4. Enable SO for all AI agents, regardless of whether they natively support it
+
+### Considered Options
+
+1. `RunAsync<T>` as an instance method of `AIAgent` class delegating to virtual `RunCoreAsync<T>`
+2. `RunAsync<T>` as an extension method using feature collection
+3. `RunAsync<T>` as a method of the new `ITypedAIAgent` interface
+4. `RunAsync<T>` as an instance method of `AIAgent` class working via the new `AgentRunOptions.ResponseFormat` property
+
+### 1. `RunAsync<T>` as an instance method of `AIAgent` class delegating to virtual `RunCoreAsync<T>`
+
+This option adds the `RunAsync<T>` method directly to the `AIAgent` base class.
+
+```csharp
+public abstract class AIAgent
+{
+	public Task<AgentResponse<T>> RunAsync<T>(
+        IEnumerable<ChatMessage> messages,
+        AgentSession? session = null,
+        JsonSerializerOptions? serializerOptions = null,
+        AgentRunOptions? options = null,
+        CancellationToken cancellationToken = default)
+		=> this.RunCoreAsync<T>(messages, session, serializerOptions, options, cancellationToken);
+
+    protected virtual Task<AgentResponse<T>> RunCoreAsync<T>(
+        IEnumerable<ChatMessage> messages,
+        AgentSession? session = null,
+        JsonSerializerOptions? serializerOptions = null,
+        AgentRunOptions? options = null,
+        CancellationToken cancellationToken = default)
+    {
+        throw new NotSupportedException($"The agent of type '{this.GetType().FullName}' does not support typed responses.");
+    }
+}
+```
+
+Agents with native SO support override the `RunCoreAsync<T>` method to provide their implementation. If not overridden, the method throws a `NotSupportedException`.
+
+Users will call the generic `RunAsync<T>` method directly on the agent:
+
+```csharp
+AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
+
+AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
+```
+
+Decision drivers satisfied:
+1. Support arrays and primitives as SO types
+2. Support complex types as SO types
+3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
+4. Enable SO for all AI agents, regardless of whether they natively support it
+
+Pros:
+- The `AIAgent.RunAsync<T>` method is easily discoverable.
+- Both the SO decorator and `ChatClientAgent` have compile-time access to the type `T`, allowing them to use the native `IChatClient.GetResponseAsync<T>` API, which handles primitives and collections seamlessly.
+
+Cons:
+- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
+- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.
+- All `AIAgent` decorators must override `RunCoreAsync<T>` to properly handle `RunAsync<T>` calls.
+
+### 2. `RunAsync<T>` as an extension method using feature collection
+
+This option uses the Agent Framework feature collection (implemented via `AgentRunOptions.AdditionalProperties`) to pass a `StructuredOutputFeature` to agents, signaling that SO is requested.
+
+Agents with native SO support check for this feature. If present, they read the target type, build the schema, invoke the underlying API, and store the response back in the feature.
+```csharp
+public class StructuredOutputFeature
+{
+    public StructuredOutputFeature(Type outputType)
+    {
+        this.OutputType = outputType;
+    }
+
+    [JsonIgnore]
+    public Type OutputType { get; set; }
+
+    public JsonSerializerOptions? SerializerOptions { get; set; }
+
+    public AgentResponse? Response { get; set; }
+}
+```
+
+The `RunAsync<T>` extension method for `AIAgent` adds this feature to the collection.
+```csharp
+public static async Task<AgentResponse<T>> RunAsync<T>(
+    this AIAgent agent,
+    IEnumerable<ChatMessage> messages,
+    AgentSession? session = null,
+    JsonSerializerOptions? serializerOptions = null,
+    AgentRunOptions? options = null,
+    CancellationToken cancellationToken = default)
+{
+    // Create the structured output feature.
+    StructuredOutputFeature structuredOutputFeature = new(typeof(T))
+    {
+        SerializerOptions = serializerOptions,
+    };
+
+    // Register it in the feature collection.
+    ((options ??= new AgentRunOptions()).AdditionalProperties ??= []).Add(typeof(StructuredOutputFeature).FullName!, structuredOutputFeature);
+
+    var response = await agent.RunAsync(messages, session, options, cancellationToken).ConfigureAwait(false);
+
+    if (structuredOutputFeature.Response is not null)
+    {
+        return new StructuredOutputResponse<T>(structuredOutputFeature.Response, response, serializerOptions);
+    }
+
+    throw new InvalidOperationException("No structured output response was generated by the agent.");
+}
+```
+
+Users will call the `RunAsync<T>` extension method directly on the agent:
+
+```csharp
+AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
+
+AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
+```
+
+Decision drivers satisfied:
+1. Support arrays and primitives as SO types
+2. Support complex types as SO types
+3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
+4. Enable SO for all AI agents, regardless of whether they natively support it
+
+Pros:
+- The `RunAsync<T>` extension method is easily discoverable.
+- The `AIAgent` public API surface remains unchanged.
+- No changes required to `AIAgent` decorators.
+
+Cons:
+- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
+- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.
+
+### 3. `RunAsync<T>` as a method of the new `ITypedAIAgent` interface
+
+This option defines a new `ITypedAIAgent` interface that agents with SO support implement. Agents without SO support do not implement it, allowing users to check for SO capability via interface detection.
+
+The interface:
+```csharp
+public interface ITypedAIAgent
+{
+    Task<AgentResponse<T>> RunAsync<T>(
+        IEnumerable<ChatMessage> messages,
+        AgentSession? session = null,
+        JsonSerializerOptions? serializerOptions = null,
+        AgentRunOptions? options = null,
+        CancellationToken cancellationToken = default);
+
+    ...
+}
+```
+
+Agents with SO support implement this interface:
+```csharp
+public sealed partial class ChatClientAgent : AIAgent, ITypedAIAgent
+{
+    public async Task<AgentResponse<T>> RunAsync<T>(
+        IEnumerable<ChatMessage> messages,
+        AgentSession? session = null,
+        JsonSerializerOptions? serializerOptions = null,
+        AgentRunOptions? options = null,
+        CancellationToken cancellationToken = default)
+    {
+        ...
+    }
+}
+```
+
+However, `ChatClientAgent` presents a challenge: it can work with chat clients that either support or do not support SO. Implementing the interface does not guarantee 
+the underlying chat client supports SO, which undermines the core idea of using interface detection to determine SO capability.
+
+Additionally, to allow users to access interface methods on decorated agents, all decorators must implement `ITypedAIAgent`. This makes it difficult for users to 
+determine whether the underlying agent actually supports SO, further weakening the purpose of this approach.
+
+Furthermore, users would have to probe the agent type to check if it implements the `ITypedAIAgent` interface and cast it accordingly to access the `RunAsync<T>` methods.
+This adds friction to the user experience. A `RunAsync<T>` extension method for `AIAgent` could be provided to alleviate that.
+
+Given these drawbacks, this option is more complex to implement than the others without providing clear benefits.
+
+Decision drivers satisfied:
+1. Support arrays and primitives as SO types
+2. Support complex types as SO types
+3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
+4. Enable SO for all AI agents, regardless of whether they natively support it
+
+Pros:
+- Both the SO decorator and `ChatClientAgent` have compile-time access to the type `T`, allowing them to use the native `IChatClient.GetResponseAsync<T>` API, which handles primitives and collections seamlessly.
+
+Cons:
+- `ChatClientAgent` implementing `ITypedAIAgent` may be misleading when the underlying chat client does not support SO.
+- All `AIAgent` decorators must implement `ITypedAIAgent` to handle `RunAsync<T>` calls.
+- Decorators implementing the interface may mislead users into thinking the underlying agent natively supports SO.
+- Agents must implement all members of `ITypedAIAgent`, not just a core method.
+- Users must check the agent type and cast to `ITypedAIAgent` to access `RunAsync<T>`.
+
+### 4. `RunAsync<T>` as an instance method of `AIAgent` class working via the new `AgentRunOptions.ResponseFormat` property
+
+This option adds a `ResponseFormat` property of type `ChatResponseFormat` to `AgentRunOptions`. Agents that support SO check for the presence of 
+this property in the options passed to `RunAsync` to determine whether structured output is requested. If present, they use the schema from `ResponseFormat` 
+to invoke the underlying API and obtain the SO response.
+
+```csharp
+public class AgentRunOptions
+{
+    public ChatResponseFormat? ResponseFormat { get; set; }
+}
+```
+
+Additionally, a generic `RunAsync<T>` method is added to `AIAgent` that initializes the `ResponseFormat` based on the type `T` and delegates to the non-generic `RunAsync`.
+
+```csharp
+public abstract class AIAgent
+{
+	public async Task<AgentResponse<T>> RunAsync<T>(
+        IEnumerable<ChatMessage> messages,
+        AgentSession? session = null,
+        JsonSerializerOptions? serializerOptions = null,
+        AgentRunOptions? options = null,
+        CancellationToken cancellationToken = default)
+    {
+        serializerOptions ??= AgentAbstractionsJsonUtilities.DefaultOptions;
+
+        var responseFormat = ChatResponseFormat.ForJsonSchema<T>(serializerOptions);
+
+        options = options?.Clone() ?? new AgentRunOptions();
+        options.ResponseFormat = responseFormat;
+
+        AgentResponse response = await this.RunAsync(messages, session, options, cancellationToken).ConfigureAwait(false);
+
+        return new AgentResponse<T>(response, serializerOptions);
+    }
+}
+```
+
+Users call the generic `RunAsync<T>` method directly on the agent:
+
+```csharp
+AIAgent agent = chatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
+
+AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
+```
+
+Decision drivers satisfied:
+1. Support arrays and primitives as SO types
+2. Support complex types as SO types
+3. Work with `AIAgent` decorators (e.g., `OpenTelemetryAgent`)
+4. Enable SO for all AI agents, regardless of whether they natively support it
+
+Pros:
+- The `AIAgent.RunAsync<T>` method is easily discoverable.
+- No changes required to `AIAgent` decorators
+
+Cons:
+- Agents without native SO support will still expose `RunAsync<T>`, which may be misleading.
+- `ChatClientAgent` exposing `RunAsync<T>` may be misleading when the underlying chat client does not support SO.

+
+## Cross-Cutting Aspects
+
+1. **The `useJsonSchemaResponseFormat` parameter**: The `ChatClientAgent.RunAsync<T>` method has this parameter to enable structured output on LLMs that do not natively support it.
+  It works by adding a user message like "Respond with a JSON value conforming to the following schema:" along with the JSON schema. However, this approach has not been reliable historically. The recommendation is not to carry this parameter forward, regardless of which option is chosen.
+
+2. **Primitives and array types handling**: There are a few options for how primitive and array types can be handled in the Agent Framework:
+
+   1. **Never wrap**, regardless of whether the schema is provided via `ResponseFormat` or `RunAsync<T>`.
+       - Pro: No changes needed; user has full control.
+       - Pro: No issues with unwrapping in streaming scenarios.
+       - Con: User must wrap manually.
+
+   2. **Always wrap**, regardless of whether the schema is provided via `ResponseFormat` or `RunAsync<T>`.
+       - Pro: Consistent wrapping behavior; no manual wrapping needed.
+       - Con: Inconsistent unwrapping behavior; it may be unexpected to have SO result wrapped when schema is provided via `ResponseFormat`.
+       - Con: Impossible to know if SO result is wrapped to unwrap it in streaming scenarios.
+
+   3. **Wrap only for `RunAsync<T>`** and do not wrap the schema provided via `ResponseFormat`.
+       - Pro: No unexpectedly wrapped result when schema is provided via `ResponseFormat`.
+       - Pro: Solves the problem with unwrapping in streaming scenarios.
+
+   4. **User decides** whether to wrap schema provided via `ResponseFormat` using a new `wrapPrimitivesAndArrays` property of `ChatResponseFormatJson`. For SO provided via `RunAsync<T>`, AF always wraps.
+       - Pro: No manual wrapping needed; just flip a switch.
+       - Pro: Solves the problem with unwrapping in streaming scenarios.
+       - Con: Extends the public API surface.
+
+3. **Structured output for agents without native SO support**: Some AI agents in AF do not support structured output natively. This is either because it is not part of the protocol (e.g., A2A agent) or because the agents use LLMs without structured output capabilities.
+   To address this gap, AF can provide the `StructuredOutputAgent` decorator. This decorator wraps any `AIAgent` and adds structured output support by obtaining the text response from the decorated agent and delegating it to a configured chat client for JSON transformation.
+   
+   ```csharp
+   public class StructuredOutputAgent : DelegatingAIAgent
+   {
+        private readonly IChatClient _chatClient;
+
+        public StructuredOutputAgent(AIAgent innerAgent, IChatClient chatClient)
+            : base(innerAgent)
+        {
+            this._chatClient = Throw.IfNull(chatClient);
+        }
+
+        protected override async Task<AgentResponse<T>> RunCoreAsync<T>(
+            IEnumerable<ChatMessage> messages,
+            AgentSession? session = null,
+            JsonSerializerOptions? serializerOptions = null,
+            AgentRunOptions? options = null,
+            CancellationToken cancellationToken = default)
+        {
+            // Run the inner agent first, to get back the text response we want to convert.
+            var textResponse = await this.InnerAgent.RunAsync(messages, session, options, cancellationToken).ConfigureAwait(false);
+
+            // Invoke the chat client to transform the text output into structured data.
+            ChatResponse<T> soResponse = await this._chatClient.GetResponseAsync<T>(
+                messages:
+                [
+                    new ChatMessage(ChatRole.System, "You are a json expert and when provided with any text, will convert it to the requested json format."),
+                    new ChatMessage(ChatRole.User, textResponse.Text)
+                ],
+                serializerOptions: serializerOptions ?? AgentJsonUtilities.DefaultOptions,
+                cancellationToken: cancellationToken).ConfigureAwait(false);
+
+            return new StructuredOutputAgentResponse(soResponse, textResponse);
+        }
+   }
+   ```
+
+   The decorator preserves the original response from the decorated agent and surfaces it via the `OriginalResponse` property on the returned `StructuredOutputAgentResponse`.
+   This allows users to access both the original unstructured response and the new structured response when using this decorator.
+   ```csharp
+   public class StructuredOutputAgentResponse : AgentResponse
+   {
+       internal StructuredOutputAgentResponse(ChatResponse chatResponse, AgentResponse agentResponse) : base(chatResponse)
+       {
+           this.OriginalResponse = agentResponse;
+       }
+       
+       public AgentResponse OriginalResponse { get; }
+    }
+   ```
+   
+   The decorator can be registered during the agent configuration step using the `UseStructuredOutput` extension method on `AIAgentBuilder`.
+
+   ```csharp
+   IChatClient meaiChatClient = chatClient.AsIChatClient();
+
+   AIAgent baseAgent = meaiChatClient.AsAIAgent(name: "HelpfulAssistant", instructions: "You are a helpful assistant.");
+
+   // Register the StructuredOutputAgent decorator during agent building
+   AIAgent agent = baseAgent
+       .AsBuilder()
+       .UseStructuredOutput(meaiChatClient)
+       .Build();
+
+   AgentResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>("Please provide information about John Smith, who is a 35-year-old software engineer.");
+
+   Console.WriteLine($"Name: {response.Result.Name}");
+   Console.WriteLine($"Age: {response.Result.Age}");
+   Console.WriteLine($"Occupation: {response.Result.Occupation}");
+   
+   var originalResponse = ((StructuredOutputAgentResponse)response.RawRepresentation!).OriginalResponse;
+   Console.WriteLine($"Original unstructured response: {originalResponse.Text}");
+
+   ```
+
+## Decision Outcome
+
+It was decided to keep both approaches for structured output - via `ResponseFormat` and via `RunAsync<T>` since they serve different scenarios and use cases.
+
+For the `RunAsync<T>` approach, option 4 was selected, which adds a generic `RunAsync<T>` method to `AIAgent` that works via the new `AgentRunOptions.ResponseFormat` property.
+This was chosen for its simplicity and because no changes are required to existing `AIAgent` decorators.
+
+For cross-cutting aspects, the `useJsonSchemaResponseFormat` parameter will not be carried forward due to reliability issues.
+
+For handling primitives and array types, option 3 was selected: wrap only for `RunAsync<T>` and do not wrap the schema provided via `ResponseFormat`.
+This avoids the issues described in the Approach 1 section note.
+
+Finally, it was decided not to include the `StructuredOutputAgent` decorator in the framework, since the reliability of producing structured output via an additional
+LLM call may not be sufficient for all scenarios. Instead, this pattern is provided as a sample to demonstrate how structured output can be achieved for agents without native support,
+giving users a reference implementation they can adapt to their own requirements.

+## Scope
+
+This directory contains feature documentation for the durable agents integration. The source code and samples live elsewhere:
+
+- .NET implementation: `dotnet/src/Microsoft.Agents.AI.DurableTask/` and `dotnet/src/Microsoft.Agents.AI.Hosting.AzureFunctions/`
+- Python implementation: `python/packages/durabletask/` and `python/packages/azurefunctions/` (package `agent-framework-azurefunctions`)
+- .NET samples: `dotnet/samples/Durable/Agents/`
+- Python samples: `python/samples/04-hosting/durabletask/`
+- Official docs (Microsoft Learn): <https://learn.microsoft.com/agent-framework/integrations/azure-functions>
+
+## Document structure
+
+| File | Purpose |
+| --- | --- |
+| `README.md` | Main technical overview: architecture, hosting models, orchestration patterns, and links to samples. |
+| `durable-agents-ttl.md` | Deep-dive on session Time-To-Live (TTL) configuration and behavior. |
+
+Add new sibling documents when a topic is too detailed for the README (e.g., a new feature like reliable streaming or MCP tool exposure). Keep the README focused on orientation and link out to siblings for depth.
+
+## Writing guidelines
+
+- **Audience**: Developers already familiar with the Microsoft Agent Framework who want to understand what durability adds and how to use it.
+- **Host-agnostic first**: Durable agents work in console apps, Azure Functions, and any Durable Task–compatible host. Show host-agnostic patterns (plain orchestration functions, `IServiceCollection` registration) before Azure Functions–specific patterns. Avoid giving the impression that Azure Functions is the only hosting option.
+- **Both languages**: Always include C# and Python examples side by side. Keep them equivalent in functionality.
+- **Callout syntax**: Use GitHub-flavored callouts (`> [!NOTE]`, `> [!IMPORTANT]`, `> [!WARNING]`) rather than bold-text callouts (`> **Note:** ...`).
+- **Line length**: Do not wrap long lines. Rely on text viewers / renderers for line wrapping.
+- **Tables**: Use spaces around pipes in separator rows (`| --- |` not `|---|`).
+- **Code snippets**: Keep them minimal and self-contained. Omit boilerplate (using statements, environment variable reads) unless the snippet is specifically about setup.
+- **Cross-references**: Link to Microsoft Learn for conceptual background (Durable Entities, Durable Task Scheduler, Azure Functions). Link to sibling docs within this directory for feature deep-dives.

+# Durable agents
+
+## Overview
+
+Durable agents extend the standard Microsoft Agent Framework with **durable state management** powered by the Durable Task framework. An ordinary Agent Framework agent runs in-process: its conversation history lives in memory and is lost when the process ends. A durable agent persists conversation history and execution state in external storage so that sessions survive process restarts, failures, and scale-out events.
+
+| Capability | Ordinary agent | Durable agent |
+| --- | --- | --- |
+| Conversation history | In-memory only | Durably persisted |
+| Failure recovery | State lost on crash | Automatically resumed |
+| Multi-instance scale-out | Not supported | Any worker can resume a session |
+| Multi-agent orchestrations | Manual coordination | Deterministic, checkpointed workflows |
+| Human-in-the-loop | Must keep process alive | Can wait days/weeks with zero compute |
+| Hosting | Any process | Console app, Azure Functions, or any Durable Task–compatible host |
+
+> [!NOTE]
+> For a step-by-step tutorial and deployment guidance, see [Azure Functions (Durable)](https://learn.microsoft.com/agent-framework/integrations/azure-functions) on Microsoft Learn.
+
+## How durable agents work
+
+Durable agents are implemented on top of [Durable Entities](https://learn.microsoft.com/azure/azure-functions/durable/durable-functions-entities) (also called "virtual actors"). Each **agent session** maps to one entity instance whose state contains the full conversation history. When you send a message to a durable agent, the following happens:
+
+1. The message is dispatched to the entity identified by an `AgentSessionId` (a composite of the agent name and a unique session key).
+2. The entity loads its persisted `DurableAgentState`, which includes the complete conversation history.
+3. The entity invokes the underlying `AIAgent` with the full conversation history, collects the response, and appends both the request and the response to the state.
+4. The updated state is persisted back to durable storage automatically.
+
+Because the entity framework serializes access to each entity instance, concurrent messages to the same session are processed one at a time, eliminating race conditions.
+
+### Agent session identity
+
+Every durable agent session is identified by an `AgentSessionId`, which has two components:
+
+- **Name** – the registered name of the agent (case-insensitive).
+- **Key** – a unique session key (case-sensitive), typically a GUID.
+
+The session ID is mapped to an underlying Durable Task entity ID with a `dafx-` prefix (e.g., `dafx-joker`). This naming convention is consistent across both .NET and Python implementations.
+
+## Architecture
+
+### .NET
+
+The .NET implementation consists of two NuGet packages:
+
+| Package | Purpose |
+| --- | --- |
+| `Microsoft.Agents.AI.DurableTask` | Core durable agent types: `DurableAIAgent`, `AgentEntity`, `DurableAgentSession`, `AgentSessionId`, `DurableAgentsOptions`, and the state model. |
+| `Microsoft.Agents.AI.Hosting.AzureFunctions` | Azure Functions hosting integration: auto-generated HTTP endpoints, MCP tool triggers, entity function triggers, and the `ConfigureDurableAgents` extension method on `FunctionsApplicationBuilder`. |
+
+Key types:
+
+- **`DurableAIAgent`** – A subclass of `AIAgent` used *inside orchestrations*. Obtained via `context.GetAgent("agentName")`, it routes `RunAsync` calls through the orchestration's entity APIs so that each call is checkpointed.
+- **`DurableAIAgentProxy`** – A subclass of `AIAgent` used *outside orchestrations* (e.g., from HTTP triggers or console apps). It signals the entity via `DurableTaskClient` and polls for the response.
+- **`AgentEntity`** – The `TaskEntity<DurableAgentState>` that hosts the real agent. It loads the registered `AIAgent` by name, wraps it in an `EntityAgentWrapper`, feeds it the full conversation history, and persists the result.
+- **`DurableAgentSession`** – An `AgentSession` subclass that carries the `AgentSessionId`.
+- **`DurableAgentsOptions`** – Builder for registering agents and configuring TTL.
+
+### Python
+
+The core Python implementation is in the `agent-framework-durabletask` package (`python/packages/durabletask`). Azure Functions hosting (including `AgentFunctionApp`) is in the separate `agent-framework-azurefunctions` package (`python/packages/azurefunctions`).
+
+Key types:
+
+- **`DurableAIAgent`** – A generic proxy (`DurableAIAgent[TaskT]`) implementing `SupportsAgentRun`. Returns a `TaskT` from `run()` — either an `AgentResponse` (client context) or a `DurableAgentTask` (orchestration context, must be `yield`ed).
+- **`DurableAIAgentWorker`** – Wraps a `TaskHubGrpcWorker` and registers agents as durable entities via `add_agent()`.
+- **`DurableAIAgentClient`** – Wraps a `TaskHubGrpcClient` for external callers. `get_agent()` returns a `DurableAIAgent[AgentResponse]`.
+- **`DurableAIAgentOrchestrationContext`** – Wraps an `OrchestrationContext` for use inside orchestrations. `get_agent()` returns a `DurableAIAgent[DurableAgentTask]`.
+- **`AgentEntity`** – Platform-agnostic agent execution logic that manages state, invokes the agent, handles streaming, and calls response callbacks.
+
+## Hosting models
+
+### Azure Functions
+
+The recommended production hosting model. A single call to `ConfigureDurableAgents` (C#) or `AgentFunctionApp` (Python) automatically:
+
+- Registers agent entities with the Durable Task worker.
+- Generates HTTP endpoints at `/api/agents/{agentName}/run` for each registered agent.
+- Supports `thread_id` query parameter / JSON field and the `x-ms-thread-id` response header for session continuity.
+- Supports fire-and-forget via the `x-ms-wait-for-response: false` header (returns HTTP 202).
+- Optionally exposes agents as MCP tools.
+
+**C# example:**
+
+```csharp
+using IHost app = FunctionsApplication
+    .CreateBuilder(args)
+    .ConfigureFunctionsWebApplication()
+    .ConfigureDurableAgents(options => options.AddAIAgent(agent))
+    .Build();
+app.Run();
+```
+
+**Python example:**
+
+```python
+app = AgentFunctionApp(agents=[agent])
+```
+
+### Console apps / generic hosts
+
+For self-hosted or non-serverless scenarios, register durable agents via `IServiceCollection.ConfigureDurableAgents` (.NET) or `DurableAIAgentWorker` (Python) with explicit Durable Task worker and client configuration.
+
+**C# example:**
+
+```csharp
+IHost host = Host.CreateDefaultBuilder(args)
+    .ConfigureServices(services =>
+    {
+        services.ConfigureDurableAgents(
+            options => options.AddAIAgent(agent),
+            workerBuilder: b => b.UseDurableTaskScheduler(connectionString),
+            clientBuilder: b => b.UseDurableTaskScheduler(connectionString));
+    })
+    .Build();
+```
+
+**Python example:**
+
+```python
+worker = DurableAIAgentWorker(TaskHubGrpcWorker(host_address="localhost:4001"))
+worker.add_agent(agent)
+worker.start()
+```
+
+## Deterministic multi-agent orchestrations
+
+Durable agents can be composed into deterministic, checkpointed workflows using Durable Task orchestrations. The orchestration framework replays orchestrator code on failure, so completed agent calls are not re-executed.
+
+### Patterns
+
+| Pattern | Description |
+| --- | --- |
+| **Sequential (chaining)** | Call agents one after another, passing outputs forward. |
+| **Parallel (fan-out/fan-in)** | Run multiple agents concurrently and aggregate results. |
+| **Conditional** | Branch orchestration logic based on structured agent output. |
+| **Human-in-the-loop** | Pause for external events (approvals, feedback) with optional timeouts. |
+
+### Using agents in orchestrations
+
+Inside an orchestration function, obtain a `DurableAIAgent` via the orchestration context. Each agent gets its own session (created with `CreateSessionAsync` / `create_session`), and you can call the same agent multiple times on the same session to maintain conversation context across sequential invocations.
+
+**C#:**
+
+```csharp
+static async Task<string> WritingOrchestration(TaskOrchestrationContext context)
+{
+    // Get a durable agent reference — works in any host (console app, Azure Functions, etc.)
+    DurableAIAgent writer = context.GetAgent("WriterAgent");
+
+    // Create a session to maintain conversation context across multiple calls
+    AgentSession session = await writer.CreateSessionAsync();
+
+    // First call: generate an initial draft
+    AgentResponse<TextResponse> draft = await writer.RunAsync<TextResponse>(
+        message: "Write a concise inspirational sentence about learning.",
+        session: session);
+
+    // Second call: refine the draft — the agent sees the full conversation history
+    AgentResponse<TextResponse> refined = await writer.RunAsync<TextResponse>(
+        message: $"Improve this further while keeping it under 25 words: {draft.Result.Text}",
+        session: session);
+
+    return refined.Result.Text;
+}
+```
+
+**Python:**
+
+```python
+def writing_orchestration(context, _):
+    agent_ctx = DurableAIAgentOrchestrationContext(context)
+
+    # Get a durable agent reference — works in any host (standalone worker, Azure Functions, etc.)
+    writer = agent_ctx.get_agent("WriterAgent")
+
+    # Create a session to maintain conversation context across multiple calls
+    session = writer.create_session()
+
+    # First call: generate an initial draft
+    draft = yield writer.run(
+        messages="Write a concise inspirational sentence about learning.",
+        session=session,
+    )
+
+    # Second call: refine the draft — the agent sees the full conversation history
+    refined = yield writer.run(
+        messages=f"Improve this further while keeping it under 25 words: {draft.text}",
+        session=session,
+    )
+
+    return refined.text
+```
+
+> [!IMPORTANT]
+> In .NET, `DurableAIAgent.RunAsync<T>` deliberately avoids `ConfigureAwait(false)` because the Durable Task Framework uses a custom synchronization context — all continuations must run on the orchestration thread.
+
+## Streaming and response callbacks
+
+Durable agents do not support true end-to-end streaming because entity operations are request/response. However, **reliable streaming** is supported via response callbacks:
+
+- **`IAgentResponseHandler`** (.NET) or **`AgentResponseCallbackProtocol`** (Python) – Implement this interface to receive streaming updates as the underlying agent generates them (e.g., push tokens to a Redis Stream for client consumption).
+- The entity still returns the complete `AgentResponse` after the stream is fully consumed.
+- Clients can reconnect and resume reading from a cursor-based stream (e.g., Redis Streams) without losing messages.
+
+See the **Reliable Streaming** samples for a complete implementation using Redis Streams.
+
+## Session TTL (Time-To-Live)
+
+Durable agent sessions support automatic cleanup via configurable TTL. See [Session TTL](durable-agents-ttl.md) for details on configuration, behavior, and best practices.
+
+## Observability
+
+When using the [Durable Task Scheduler](https://learn.microsoft.com/azure/azure-functions/durable/durable-task-scheduler/durable-task-scheduler) as the durable backend, you get built-in observability through its dashboard:
+
+- **Conversation history** – View complete chat history for each agent session.
+- **Orchestration visualization** – See multi-agent execution flows, including parallel branches and conditional logic.
+- **Performance metrics** – Monitor agent response times, token usage, and orchestration duration.
+- **Debugging** – Trace tool invocations and external event handling.
+
+## Samples

+## Build, Test, and Lint Commands
+
+```bash
+# From dotnet/ directory
+dotnet restore --tl:off   # Restore dependencies for all projects
+dotnet build --tl:off     # Build all projects
+dotnet test               # Run all tests
+dotnet format             # Auto-fix formatting for all projects
+
+# Build/test/format a specific project (preferred for isolated/internal changes)
+dotnet build src/Microsoft.Agents.AI.<Package> --tl:off
+dotnet test tests/Microsoft.Agents.AI.<Package>.UnitTests
+dotnet format src/Microsoft.Agents.AI.<Package>
+
+# Run a single test
+dotnet test --filter "FullyQualifiedName~Namespace.TestClassName.TestMethodName"
+
+# Run unit tests only
+dotnet test --filter FullyQualifiedName\~UnitTests
+```
+
+Use `--tl:off` when building to avoid flickering when running commands in the agent.
+
+## Speeding Up Builds and Testing
+
+The full solution is large. Use these shortcuts:
+
+| Change type | What to do |
+|-------------|------------|
+| Isolated/Internal logic | Build only the affected project and its `*.UnitTests` project. Fix issues, then build the full solution and run all unit tests. |
+| Public API surface | Build the full solution and run all unit tests immediately. |
+
+Example: Building a single code project for all target frameworks
+
+```bash
+# From dotnet/ directory
+dotnet build ./src/Microsoft.Agents.AI.Abstractions
+```
+
+Example: Building a single code project for just .NET 10.
+
+```bash
+# From dotnet/ directory
+dotnet build ./src/Microsoft.Agents.AI.Abstractions -f net10.0
+```
+
+Example: Running tests for a single project using .NET 10.
+
+```bash
+# From dotnet/ directory
+dotnet test ./tests/Microsoft.Agents.AI.Abstractions.UnitTests -f net10.0
+```
+
+Example: Running a single test in a specific project using .NET 10.
+Provide the full namespace, class name, and method name for the test you want to run:
+
+```bash
+# From dotnet/ directory
+dotnet test ./tests/Microsoft.Agents.AI.Abstractions.UnitTests -f net10.0 --filter "FullyQualifiedName~Microsoft.Agents.AI.Abstractions.UnitTests.AgentRunOptionsTests.CloningConstructorCopiesProperties"
+```
+
+### Multi-target framework tip
+
+Most projects target multiple .NET frameworks. If the affected code does **not** use `#if` directives for framework-specific logic, pass `-f net10.0` to speed up building and testing.
+
+### Package Restore tip
+
+`dotnet build` will try and restore packages for all projects on each build, which can be slow.
+Unless packages have been changed, or it's the first time building the solution, add `--no-restore` to the build command to skip this step and speed up builds.
+
+Just remember to run `dotnet restore` after pulling changes, making changes to project references, or when building for the first time.
+
+### Testing on Linux tip
+
+Unit tests target both .NET Framework as well as .NET Core. When running on Linux, only the .NET Core tests can be run, as .NET Framework is not supported on Linux.
+
+To run only the .NET Core tests, use the `-f net10.0` option with `dotnet test`.

+name: verify-dotnet-samples
+description: How to build, run and verify the .NET sample projects in the Agent Framework repository. Use this when a user wants to verify that the samples still function as expected.
+---
+
+# Verifying .NET Sample Projects
+
+## Sample Pre-requisites
+
+We should only support verifying samples that:
+1. Use environment variables for configuration.
+2. Have no complex setup requirements, e.g., where multiple applications need to be run together, or where we need to launch a browser, etc.
+
+Always report to the user which samples were run and which were not, and why.
+
+## Verifying a sample
+
+Samples should be verified to ensure that they actually work as intended and that their output matches what is expected.
+For each sample that is run, output should be produced that shows the result and explains the reasoning about what output
+was expected, what was produced, and why it didn't match what the sample was expected to produce.
+
+Steps to verify a sample:
+1. Read the code for the sample
+1. Check what environment variables are required for the sample
+1. Check if each environment variable has been set
+1. If there are any missing, give the user a list of missing environment variables to set and terminate
+1. Summarize what the expected output of the sample should be
+1. Run the sample
+1. Show the user any output from the sample run as it gets produced, so that they can see the run progress
+1. Check the output of the run against expectations
+1. After running all requested samples, produce output for each sample that was verified:
+  1. If expectations were matched, output the following:
+     ```text
+     [Sample Name] Succeeded
+     ```
+  1. If expectations were not matched, output the following:
+     ```text
+     [Sample Name] Failed
+     Actual Output:
+     [What the sample produced]
+     Expected Output:
+     [Explanation of what was expected and why the actual output didn't match expectations]
+     ```
+
+## Environment Variables
+
+Most samples use environment variables to configure settings.
+
+```csharp
+var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT") ?? throw new InvalidOperationException("AZURE_OPENAI_ENDPOINT is not set.");
+var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME") ?? "gpt-4o-mini";
+```
+
+To run a sample, the environment variables should be set first.
+Before running a sample, check whether each environment variable in the sample has a value and
+then give the user a list of environment variables to set.
+
+You can provide the user some examples of how to set the variables like this:
+
+```bash
+export AZURE_OPENAI_ENDPOINT="https://my-openai-instance.openai.azure.com/"
+export AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
+```
+
+To check if a variable has a value use e.g.:
+
+```bash
+echo $AZURE_OPENAI_ENDPOINT
+```
+
+## How to Run a Sample (General Pattern)
+
+```bash
+cd dotnet/samples/<category>/<sample-dir>
+dotnet run
+```
+
+For multi-targeted projects (e.g., Durable console apps), specify the framework:
+
+```bash
+dotnet run --framework net10.0

+- `AIAgent`: The abstract base class that all agents derive from, providing common methods for interacting with an agent.
+- `AgentSession`: The abstract base class that all agent sessions derive from, representing a conversation with an agent.
+- `ChatClientAgent`: An `AIAgent` implementation that uses an `IChatClient` to send messages to an AI provider and receive responses.
+- `IChatClient`: Interface for sending messages to an AI provider and receiving responses. Used by `ChatClientAgent` and implemented by provider-specific packages.
+- `FunctionInvokingChatClient`: Decorator for `IChatClient` that adds function invocation capabilities.
+- `AITool`: Represents a tool that an agent/AI provider can use, with metadata and an execution delegate.
+- `AIFunction`: A specific type of `AITool` that represents a local function the agent/AI provider can call, with parameters and return types defined.
+- `ChatMessage`: Represents a message in a conversation.
+- `AIContent`: Represents content in a message, which can be text, a function call, tool output and more.

 ### External Dependencies

-The framework integrates with `Microsoft.Extensions.AI` and `Microsoft.Extensions.AI.Abstractions` (external NuGet packages) using types like `IChatClient`, `FunctionInvokingChatClient`, `AITool`, and `AIContent`.
