-# Feature Collections
-
-## Context and Problem Statement
-
-When using agents, we often have cases where we want to pass some arbitrary services or data to an agent or some component in the agent execution stack.
-These services or data are not necessarily known at compile time and can vary by the agent stack that the user has built.
-E.g., there may be an agent decorator or chat client decorator that was added to the stack by the user, and an arbitrary payload needs to be passed to that decorator.
-
-Since these payloads are related to components that are not integral parts of the agent framework, they cannot be added as strongly typed settings to the agent run options.
-However, the payloads could be added to the agent run options as loosely typed 'features', that can be retrieved as needed.
-
-In some cases certain classes of agents may support the same capability, but not all agents do.
-Having the configuration for such a capability on the main abstraction would advertise the functionality to all users, even if their chosen agent does not support it.
-The user may type test for certain agent types, and call overloads on the appropriate agent types, with the strongly typed configuration.
-Having a feature collection though, would be an alternative way of passing such configuration, without needing to type check the agent type.
-All agents that support the functionality would be able to check for the configuration and use it, simplifying the user code.
-If the agent does not support the capability, that configuration would be ignored.
-
-### Sample Scenario 1 - Per Run ChatMessageStore Override for hosting Libraries
-
-We are building an agent hosting library, that can host any agent built using the agent framework.
-Where an agent is not built on a service that uses in-service chat history storage, the hosting library wants to force the agent to use
-the hosting library's chat history storage implementation.
-This chat history storage implementation may be specifically tailored to the type of protocol that the hosting library uses, e.g. conversation id based storage or response id based storage.
-The hosting library does not know what type of agent it is hosting, so it cannot provide a strongly typed parameter on the agent.
-Instead, it adds the chat history storage implementation to a feature collection, and if the agent supports custom chat history storage, it retrieves the implementation from the feature collection and uses it.
-
-```csharp
-// Pseudo-code for an agent hosting library that supports conversation id based hosting.
-public async Task<string> HandleConversationsBasedRequestAsync(AIAgent agent, string conversationId, string userInput)
-{
-    var thread = await this._threadStore.GetOrCreateThread(conversationId);
-
-    // The hosting library can set a per-run chat message store via Features that only applies for that run.
-    // This message store will load and save messages under the conversation id provided.
-    ConversationsChatMessageStore messageStore = new(this._dbClient, conversationId);
-    var response = await agent.RunAsync(
-        userInput,
-        thread,
-        options: new AgentRunOptions()
-        {
-            Features = new AgentFeatureCollection().WithFeature<ChatMessageStore>(messageStore)
-        });
-
-    await this._threadStore.SaveThreadAsync(conversationId, thread);
-    return response.Text;
-}
-
-// Pseudo-code for an agent hosting library that supports response id based hosting.
-public async Task<(string responseMessage, string responseId)> HandleResponseIdBasedRequestAsync(AIAgent agent, string previousResponseId, string userInput)
-{
-    var thread = await this._threadStore.GetOrCreateThreadAsync(previousResponseId);
-
-    // The hosting library can set a per-run chat message store via Features that only applies for that run.
-    // This message store will buffer newly added messages until explicitly saved after the run.
-    ResponsesChatMessageStore messageStore = new(this._dbClient, previousResponseId);
-
-    var response = await agent.RunAsync(
-        userInput,
-        thread,
-        options: new AgentRunOptions()
-        {
-            Features = new AgentFeatureCollection().WithFeature<ChatMessageStore>(messageStore)
-        });
-
-    // Since the message store may not actually have been used at all (if the agent's underlying chat client requires service-based chat history storage),
-    // we may not have anything to save back to the database.
-    // We still want to generate a new response id though, so that we can save the updated thread state under that id.
-    // We should also use the same id to save any buffered messages in the message store if there are any.
-    var newResponseId = this.GenerateResponseId();
-    if (messageStore.HasBufferedMessages)
-    {
-        await messageStore.SaveBufferedMessagesAsync(newResponseId);
-    }
-    
-    // Save the updated thread state under the new response id that was generated by the store.
-    await this._threadStore.SaveThreadAsync(newResponseId, thread);
-    return (response.Text, newResponseId);
-}
-```
-
-### Sample Scenario 2 - Structured output
-
-Currently our base abstraction does not support structured output, since the capability is not supported by all agents.
-For those agents that don't support structured output, we could add an agent decorator that takes the response from the underlying agent, and applies structured output parsing on top of it via an additional LLM call.
-
-If we add structured output configuration as a feature, then any agent that supports structured output could retrieve the configuration from the feature collection and apply it, and where it is not supported, the configuration would simply be ignored.
-
-We could add a simple StructuredOutputAgentFeature that can be added to the list of features and also be used to return the generated structured output.
-
-```csharp
-internal class StructuredOutputAgentFeature
-{
-    public Type? OutputType { get; set; }
-
-    public JsonSerializerOptions? SerializerOptions { get; set; }
-
-    public bool? UseJsonSchemaResponseFormat { get; set; }
-
-    // Contains the result of the structured output parsing request.
-    public ChatResponse? ChatResponse { get; set; }
-}
-```
-
-We can add a simple decorator class that does the chat client invocation.
-
-```csharp
-public class StructuredOutputAgent : DelegatingAIAgent
-{
-    private readonly IChatClient _chatClient;
-    public StructuredOutputAgent(AIAgent innerAgent, IChatClient chatClient)
-        : base(innerAgent)
-    {
-        this._chatClient = Throw.IfNull(chatClient);
-    }
-
-    public override async Task<AgentRunResponse> RunAsync(
-        IEnumerable<ChatMessage> messages,
-        AgentThread? thread = null,
-        AgentRunOptions? options = null,
-        CancellationToken cancellationToken = default)
-    {
-        // Run the inner agent first, to get back the text response we want to convert.
-        var response = await base.RunAsync(messages, thread, options, cancellationToken).ConfigureAwait(false);
-
-        if (options?.Features?.TryGet<StructuredOutputAgentFeature>(out var responseFormatFeature) is true
-            && responseFormatFeature.OutputType is not null)
-        {
-            // Create the chat options to request structured output.
-            ChatOptions chatOptions = new()
-            {
-                ResponseFormat = ChatResponseFormat.ForJsonSchema(responseFormatFeature.OutputType, responseFormatFeature.SerializerOptions)
-            };
-
-            // Invoke the chat client to transform the text output into structured data.
-            // The feature is updated with the result.
-            // The code can be simplified by adding a non-generic structured output GetResponseAsync
-            // overload that takes Type as input.
-            responseFormatFeature.ChatResponse = await this._chatClient.GetResponseAsync(
-                messages: new[]
-                {
-                    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, response.Text)
-                },
-                options: chatOptions,
-                cancellationToken: cancellationToken).ConfigureAwait(false);
-        }
-
-        return response;
-    }
-}
-```
-
-Finally, we can add an extension method on `AIAgent` that can add the feature to the run options and check the feature for the structured output result and add the deserialized result to the response.
-
-```csharp
-public static async Task<AgentRunResponse<T>> RunAsync<T>(
-    this AIAgent agent,
-    IEnumerable<ChatMessage> messages,
-    AgentThread? thread = null,
-    JsonSerializerOptions? serializerOptions = null,
-    AgentRunOptions? options = null,
-    bool? useJsonSchemaResponseFormat = null,
-    CancellationToken cancellationToken = default)
-{
-    // Create the structured output feature.
-    var structuredOutputFeature = new StructuredOutputAgentFeature();
-    structuredOutputFeature.OutputType = typeof(T);
-    structuredOutputFeature.UseJsonSchemaResponseFormat = useJsonSchemaResponseFormat;
-
-    // Run the agent.
-    options ??= new AgentRunOptions();
-    options.Features ??= new AgentFeatureCollection();
-    options.Features.Set(structuredOutputFeature);
-
-    var response = await agent.RunAsync(messages, thread, options, cancellationToken).ConfigureAwait(false);
-
-    // Deserialize the JSON output.
-    if (structuredOutputFeature.ChatResponse is not null)
-    {
-        var typed = new ChatResponse<T>(structuredOutputFeature.ChatResponse, serializerOptions ?? AgentJsonUtilities.DefaultOptions);
-        return new AgentRunResponse<T>(response, typed.Result);
-    }
-
-    throw new InvalidOperationException("No structured output response was generated by the agent.");
-}
-```
-
-We can then use the extension method with any agent that supports structured output or that has
-been decorated with the `StructuredOutputAgent` decorator.
-
-```csharp
-agent = new StructuredOutputAgent(agent, chatClient);
-
-AgentRunResponse<PersonInfo> response = await agent.RunAsync<PersonInfo>([new ChatMessage(
-    ChatRole.User,
-    "Please provide information about John Smith, who is a 35-year-old software engineer.")]);
-```
-
-## Implementation Options
-
-Three options were considered for implementing feature collections:
-
-- **Option 1**: FeatureCollections similar to ASP.NET Core
-- **Option 2**: AdditionalProperties Dictionary
-- **Option 3**: IServiceProvider
-
-Here are some comparisons about their suitability for our use case:
-
-| Criteria         | Feature Collection | Additional Properties | IServiceProvider |
-|------------------|--------------------|-----------------------|------------------|
-|Ease of use       |✅ Good             |❌ Bad                |✅ Good           |
-|User familiarity  |❌ Bad              |✅ Good               |✅ Good           |
-|Type safety       |✅ Good             |❌ Bad                |✅ Good           |
-|Ability to modify registered options when progressing down the stack|✅ Supported|✅ Supported|❌ Not-Supported (IServiceProvider is read-only)|
-|Already available in MEAI stack|❌ No|✅ Yes|❌ No|
-|Ambiguity with existing AdditionalProperties|❌ Yes|✅ No|❌ Yes|
-
-## IServiceProvider
-
-Service Collections and Service Providers provide a very popular way to register and retrieve services by type and could be used as a way to pass features to agents and chat clients.
-
-However, since IServiceProvider is read-only, it is not possible to modify the registered services when progressing down the execution stack.
-E.g. an agent decorator cannot add additional services to the IServiceProvider passed to it when calling into the inner agent.
-
-IServiceProvider also does not expose a way to list all services contained in it, making it difficult to copy services from one provider to another.
-
-This lack of mutability makes IServiceProvider unsuitable for our use case, since we will not be able to use it to build sample scenario 2.
-
-## AdditionalProperties dictionary
-
-The AdditionalProperties dictionary is already available on various options classes in the agent framework as well as in the MEAI stack and
-allows storing arbitrary key/value pairs, where the key is a string and the value is an object.
-
-While FeatureCollection uses Type as a key, AdditionalProperties uses string keys.
-This means that users need to agree on string keys to use for specific features, however it is also possible to use Type.FullName as a key by convention
-to avoid key collisions, which is an easy convention to follow.
-
-Since the value of AdditionalProperties is of type object, users need to cast the value to the expected type when retrieving it, which is also
-a drawback, but when using the convention of using Type.FullName as a key, there is at least a clear expectation of what type to cast to.
-
-```csharp
-// Setting a feature
-options.AdditionalProperties[typeof(MyFeature).FullName] = new MyFeature();
-
-// Retrieving a feature
-if (options.AdditionalProperties.TryGetValue(typeof(MyFeature).FullName, out var featureObj)
-    && featureObj is MyFeature myFeature)
-{
-    // Use myFeature
-}
-```
-
-It would also be possible to add extension methods to simplify setting and getting features from AdditionalProperties.
-Having a base class for features should help make this more feature rich.
-
-```csharp
-// Setting a feature, this can use Type.FullName as the key.
-options.AdditionalProperties
-    .WithFeature(new MyFeature());
-
-// Retrieving a feature, this can use Type.FullName as the key.
-if (options.AdditionalProperties.TryGetFeature<MyFeature>(out var myFeature))
-{
-    // Use myFeature
-}
-```
-
-It would also be possible to add extension methods for a feature to simplify setting and getting features from AdditionalProperties.
-
-```csharp
-// Setting a feature
-options.AdditionalProperties
-    .WithMyFeature(new MyFeature());
-// Retrieving a feature
-if (options.AdditionalProperties.TryGetMyFeature(out var myFeature))
-{
-    // Use myFeature
-}
-```
-
-## Feature Collection
-
-If we choose the feature collection option, we need to decide on the design of the feature collection itself.
-
-### Feature Collections extension points
-
-We need to decide the set of actions that feature collections would be supported for. Here is the suggested list of actions:
-
-**MAAI.AIAgent:**
-
-1. GetNewThread
-    1. E.g. this would allow passing an already existing storage id for the thread to use, or an initialized custom chat message store to use.
-1. DeserializeThread
-    1. E.g. this would allow passing an already existing storage id for the thread to use, or an initialized custom chat message store to use.
-1. Run / RunStreaming
-    1. E.g. this would allow passing an override chat message store just for that run, or a desired schema for a structured output middleware component.
-
-**MEAI.ChatClient:**
-
-1. GetResponse / GetStreamingResponse
-
-### Reconciling with existing AdditionalProperties
-
-If we decide to add feature collections, separately from the existing AdditionalProperties dictionaries, we need to consider how to explain to users when to use each one.
-One possible approach though is to have the one use the other under the hood.
-AdditionalProperties could be stored as a feature in the feature collection.
-
-Users would be able to retrieve additional properties from the feature collection, in addition to retrieving it via a dedicated AdditionalProperties property.
-E.g. `features.Get<AdditionalPropertiesDictionary>()`
-
-One challenge with this approach is that when setting a value in the AdditionalProperties dictionary, the feature collection would need to be created first if it does not already exist.
-
-```csharp
-public class AgentRunOptions
-{
-    public AdditionalPropertiesDictionary? AdditionalProperties { get; set; }
-    public IAgentFeatureCollection? Features { get; set; }
-}
-
-var options = new AgentRunOptions();
-// This would need to create the feature collection first, if it does not already exist.
-options.AdditionalProperties ??= new AdditionalPropertiesDictionary();
-```
-
-Since IAgentFeatureCollection is an interface, AgentRunOptions would need to have a concrete implementation of the interface to create, meaning that the user cannot decide.
-It also means that if the user doesn't realise that AdditionalProperties is implemented using feature collections, they may set a value on AdditionalProperties, and then later overwrite the entire feature collection, losing the AdditionalProperties feature.
-
-Options to avoid these issues:
-
-1. Make `Features` readonly.
-    1. This would prevent the user from overwriting the feature collection after setting AdditionalProperties.
-    1. Since the user cannot set their own implementation of IAgentFeatureCollection, having an interface for it may not be necessary.
-
-### Feature Collection Implementation
-
-We have two options for implementing feature collections:
-
-1. Create our own [IAgentFeatureCollection interface](https://github.com/microsoft/agent-framework/pull/2354/files#diff-9c42f3e60d70a791af9841d9214e038c6de3eebfc10e3997cb4cdffeb2f1246d) and [implementation](https://github.com/microsoft/agent-framework/pull/2354/files#diff-a435cc738baec500b8799f7f58c1538e3bb06c772a208afc2615ff90ada3f4ca).
-2. Reuse the asp.net [IFeatureCollection interface](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/IFeatureCollection.cs) and [implementation](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/FeatureCollection.cs).
-
-#### Roll our own
-
-Advantages:
-
-Creating our own IAgentFeatureCollection interface and implementation has the advantage of being more clearly associated with the agent framework and allows us to
-improve on some of the design decisions made in asp.net core's IFeatureCollection.
-
-Drawbacks:
-
-It would mean a different implementation to maintain and test.
-
-#### Reuse asp.net IFeatureCollection
-
-Advantages:
-
-Reusing the asp.net IFeatureCollection has the advantage of being able to reuse the well-established and tested implementation from asp.net
-core. Users who are using agents in an asp.net core application may be able to pass feature collections from asp.net core to the agent framework directly.
-
-Drawbacks:
-
-While the package name is `Microsoft.Extensions.Features`, the namespaces of the types are `Microsoft.AspNetCore.Http.Features`, which may create confusion for users of agent framework who are not building web applications or services.
-Users may rightly ask: Why do I need to use a class from asp.net core when I'm not building a web application / service?
-
-The current design has some design issues that would be good to avoid.  E.g. it does not distinguish between a feature being "not set" and "null". Get returns both as null and there is no tryget method.
-Since the [default implementation](https://github.com/dotnet/aspnetcore/blob/main/src/Extensions/Features/src/FeatureCollection.cs) also supports value types, it throws for null values of value types.
-A TryGet method would be more appropriate.
-
-## Feature Layering
-
-One possible scenario when adding support for feature collections is to allow layering of features by scope.
-
-The following levels of scope could be supported:
-
-1. Application - Application wide features that apply to all agents / chat clients
-2. Artifact (Agent / ChatClient) - Features that apply to all runs of a specific agent or chat client instance
-3. Action (GetNewThread / Run / GetResponse) - Feature that apply to a single action only
-
-When retrieving a feature from the collection, the search would start from the most specific scope (Action) and progress to the least specific scope (Application), returning the first matching feature found.
-
-Introducing layering adds some challenges:
-
-- There may be multiple feature collections at the same scope level, e.g. an Agent that uses a ChatClient where both have their own feature collections.
-  - Do we layer the agent feature collection over the chat client feature collection (Application -> ChatClient -> Agent -> Run), or only use the agent feature collection in the agent (Application -> Agent -> Run), and the chat client feature collection in the chat client (Application -> ChatClient -> Run)?
-- The appropriate base feature collection may change when progressing down the stack, e.g. when an Agent calls a ChatClient, the action feature collection stays the same, but the artifact feature collection changes.
-- Who creates the feature collection hierarchy?
-  - Since the hierarchy changes as it progresses down the execution stack, and the caller can only pass in the action level feature collection, the callee needs to combine it with its own artifact level feature collection and the application level feature collection. Each action will need to build the appropriate feature collection hierarchy, at the start of its execution.
-- For Artifact level features, it seems odd to pass them in as a bag of untyped features, when we are constructing a known artifact type and therefore can have typed settings.
-  - E.g. today we have a strongly typed setting on ChatClientAgentOptions to configure a ChatMessageStore for the agent.
-- To avoid global statics for application level features, the user would need to pass in the application level feature collection to each artifact that they create.
-  - This would be very odd if the user also already has to strongly typed settings for each feature that they want to set at the artifact level.
-
-### Layering Options
-
-1. No layering - only a single feature collection is supported per action (the caller can still create a layered collection if desired, but the callee does not do any layering automatically).
-    1. Fallback is to any features configured on the artifact via strongly typed settings.
-1. Full layering - support layering at all levels (Application -> Artifact -> Action).
-    1. Only apply applicable artifact level features when calling into that artifact.
-    1. Apply upstream artifact features when calling into downstream artifacts, e.g. Feature hierarchy in ChatClientAgent would be `Application -> Agent -> Run` and in ChatClient would be `Application -> ChatClient -> Agent -> Run` or `Application -> Agent -> ChatClient -> Run`
-    1. The user needs to provide the application level feature collection to each artifact that they create and artifact features are passed via strongly typed settings.
-
-### Accessing application level features Options
-
-We need to consider how application level features would be accessed if supported.
-
-1. The user provides the application level feature collection to each artifact that the user constructs
-    1. Passing the application level feature collection to each artifact is tedious for the user.
-1. There is a static application level feature collection that can be accessed globally.
-    1. Statics create issues with testing and isolation.
-
-## Decisions

-# Single Agent Sample
-
-This sample demonstrates how to use the durable agents extension to create a simple console app that hosts a single AI agent and provides interactive conversation via stdin/stdout.
-
-## Key Concepts Demonstrated
-
-- Using the Microsoft Agent Framework to define a simple AI agent with a name and instructions.
-- Registering durable agents with the console app and running them interactively.
-- Conversation management (via threads) for isolated interactions.
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/01_SingleAgent
-dotnet run --framework net10.0
-```
-
-The app will prompt you for input. You can interact with the Joker agent:
-
-```text
-=== Single Agent Console Sample ===
-Enter a message for the Joker agent (or 'exit' to quit):
-
-You: Tell me a joke about a pirate.
-Joker: Why don't pirates ever learn the alphabet? Because they always get stuck at "C"!
-
-You: Now explain the joke.
-Joker: The joke plays on the word "sea" (C), which pirates are famously associated with...
-
-You: exit
-```
-
-## Scriptable Usage
-
-You can also pipe input to the app for scriptable usage:
-
-```bash
-echo "Tell me a joke about a pirate." | dotnet run
-```
-
-The app will read from stdin, process the input, and write the response to stdout.
-
-## Viewing Agent State
-
-You can view the state of the agent in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can view the state of the Joker agent, including its conversation history and current state
-
-The agent maintains conversation state across multiple interactions, and you can inspect this state in the dashboard to understand how the durable agents extension manages conversation context.

-# Single Agent Orchestration Sample
-
-This sample demonstrates how to use the durable agents extension to create a simple console app that orchestrates sequential calls to a single AI agent using the same conversation thread for context continuity.
-
-## Key Concepts Demonstrated
-
-- Orchestrating multiple interactions with the same agent in a deterministic order
-- Using the same `AgentThread` across multiple calls to maintain conversational context
-- Durable orchestration with automatic checkpointing and resumption from failures
-- Waiting for orchestration completion using `WaitForInstanceCompletionAsync`
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/02_AgentOrchestration_Chaining
-dotnet run --framework net10.0
-```
-
-The app will start the orchestration, wait for it to complete, and display the result:
-
-```text
-=== Single Agent Orchestration Chaining Sample ===
-Starting orchestration...
-
-Orchestration started with instance ID: 86313f1d45fb42eeb50b1852626bf3ff
-Waiting for completion...
-
-✓ Orchestration completed successfully!
-
-Result: Learning serves as the key, opening doors to boundless opportunities and a brighter future.
-```
-
-The orchestration will proceed to run the WriterAgent twice in sequence:
-
-1. First, it writes an inspirational sentence about learning
-2. Then, it refines the initial output using the same conversation thread
-
-## Viewing Orchestration State
-
-You can view the state of the orchestration in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Orchestrations**: View the orchestration instance, including its runtime status, input, output, and execution history
-   - **Agents**: View the state of the WriterAgent, including conversation history maintained across the orchestration steps
-
-The orchestration instance ID is displayed in the console output. You can use this ID to find the specific orchestration in the dashboard and inspect its execution details, including the sequence of agent calls and their results.

-# Multi-Agent Concurrent Orchestration Sample
-
-This sample demonstrates how to use the durable agents extension to create a console app that orchestrates concurrent execution of multiple AI agents using durable orchestration.
-
-## Key Concepts Demonstrated
-
-- Running multiple agents concurrently in a single orchestration
-- Using `Task.WhenAll` to wait for concurrent agent executions
-- Combining results from multiple agents into a single response
-- Waiting for orchestration completion using `WaitForInstanceCompletionAsync`
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/03_AgentOrchestration_Concurrency
-dotnet run --framework net10.0
-```
-
-The app will prompt you for a question:
-
-```text
-=== Multi-Agent Concurrent Orchestration Sample ===
-Enter a question for the agents:
-
-What is temperature?
-```
-
-The orchestration will run both agents concurrently and display their responses:
-
-```text
-Orchestration started with instance ID: 86313f1d45fb42eeb50b1852626bf3ff
-Waiting for completion...
-
-✓ Orchestration completed successfully!
-
-Physicist's response:
-Temperature is a measure of the average kinetic energy of particles in a system...
-
-Chemist's response:
-From a chemistry perspective, temperature is crucial for chemical reactions...
-```
-
-Both agents run in parallel, and the orchestration waits for both to complete before returning the combined results.
-
-## Viewing Orchestration State
-
-You can view the state of the orchestration in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Orchestrations**: View the orchestration instance, including its runtime status, input, output, and execution history
-   - **Agents**: View the state of both the PhysicistAgent and ChemistAgent, including their individual conversation histories
-
-The orchestration instance ID is displayed in the console output. You can use this ID to find the specific orchestration in the dashboard and inspect how the concurrent agent executions were coordinated, including the timing of when each agent started and completed.
-
-## Scriptable Usage
-
-You can also pipe input to the app:
-
-```bash
-echo "What is temperature?" | dotnet run
-```

-# Multi-Agent Conditional Orchestration Sample
-
-This sample demonstrates how to use the durable agents extension to create a console app that orchestrates multiple AI agents with conditional logic based on the results of previous agent interactions.
-
-## Key Concepts Demonstrated
-
-- Multi-agent orchestration with conditional branching
-- Using agent responses to determine workflow paths
-- Activity functions for non-agent operations
-- Waiting for orchestration completion using `WaitForInstanceCompletionAsync`
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/04_AgentOrchestration_Conditionals
-dotnet run --framework net10.0
-```
-
-The app will prompt you for email content. You can test both legitimate emails and spam emails:
-
-### Testing with a Legitimate Email
-
-```text
-=== Multi-Agent Conditional Orchestration Sample ===
-Enter email content:
-
-Hi John, I hope you're doing well. I wanted to follow up on our meeting yesterday about the quarterly report. Could you please send me the updated figures by Friday? Thanks!
-```
-
-The orchestration will analyze the email and display the result:
-
-```text
-Orchestration started with instance ID: 86313f1d45fb42eeb50b1852626bf3ff
-Waiting for completion...
-
-✓ Orchestration completed successfully!
-
-Result: Email sent: Thank you for your email. I'll prepare the updated figures...
-```
-
-### Testing with a Spam Email
-
-```text
-=== Multi-Agent Conditional Orchestration Sample ===
-Enter email content:
-
-URGENT! You've won $1,000,000! Click here now to claim your prize! Limited time offer! Don't miss out!
-```
-
-The orchestration will detect it as spam and display:
-
-```text
-Orchestration started with instance ID: 86313f1d45fb42eeb50b1852626bf3ff
-Waiting for completion...
-
-✓ Orchestration completed successfully!
-
-Result: Email marked as spam: Contains suspicious claims about winning money and urgent action requests...
-```
-
-## Scriptable Usage
-
-You can also pipe email content to the app:
-
-```bash
-# Test with a legitimate email
-echo "Hi John, I hope you're doing well..." | dotnet run
-
-# Test with a spam email
-echo "URGENT! You've won $1,000,000! Click here now!" | dotnet run
-```
-
-The orchestration will proceed as follows:
-
-1. The SpamDetectionAgent analyzes the email to determine if it's spam
-2. Based on the result:
-   - If spam: The orchestration calls the `HandleSpamEmail` activity function
-   - If not spam: The EmailAssistantAgent drafts a response, then the `SendEmail` activity function is called
-
-## Viewing Orchestration State
-
-You can view the state of the orchestration in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Orchestrations**: View the orchestration instance, including its runtime status, input, output, and execution history
-   - **Agents**: View the state of both the SpamDetectionAgent and EmailAssistantAgent
-
-The orchestration instance ID is displayed in the console output. You can use this ID to find the specific orchestration in the dashboard and inspect the conditional branching logic, including which path was taken based on the spam detection result.

-# Human-in-the-Loop Orchestration Sample
-
-This sample demonstrates how to use the durable agents extension to create a console app that implements a human-in-the-loop workflow using durable orchestration, including interactive approval prompts.
-
-## Key Concepts Demonstrated
-
-- Human-in-the-loop workflows with durable orchestration
-- External event handling for human approval/rejection
-- Timeout handling for approval requests
-- Iterative content refinement based on human feedback
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/05_AgentOrchestration_HITL
-dotnet run --framework net10.0
-```
-
-The app will prompt you for input:
-
-```text
-=== Human-in-the-Loop Orchestration Sample ===
-Enter topic for content generation:
-
-The Future of Artificial Intelligence
-
-Max review attempts (default: 3):
-3
-Approval timeout in hours (default: 72):
-72
-```
-
-The orchestration will generate content and prompt you for approval:
-
-```text
-Orchestration started with instance ID: 86313f1d45fb42eeb50b1852626bf3ff
-
-=== NOTIFICATION: Content Ready for Review ===
-Title: The Future of Artificial Intelligence
-
-Content:
-[Generated content appears here]
-
-Please review the content above and provide your approval.
-
-Content is ready for review. Check the logs above for details.
-Approve? (y/n): n
-Feedback (optional): Please add more details about the ethical implications.
-```
-
-The orchestration will incorporate your feedback and regenerate the content. Once approved, it will publish and complete.
-
-## Viewing Orchestration State
-
-You can view the state of the orchestration in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Orchestrations**: View the orchestration instance, including its runtime status, custom status (which shows approval state), input, output, and execution history
-   - **Agents**: View the state of the WriterAgent, including conversation history
-
-The orchestration instance ID is displayed in the console output. You can use this ID to find the specific orchestration in the dashboard and inspect:
-
-- The custom status field, which shows the current state of the approval workflow
-- When the orchestration is waiting for external events
-- The iteration count and feedback history
-- The final published content

-# Long Running Tools Sample
-
-This sample demonstrates how to use the durable agents extension to create a console app with agents that have long running tools. This sample builds on the [05_AgentOrchestration_HITL](../05_AgentOrchestration_HITL) sample by adding a publisher agent that can start and manage content generation workflows. A key difference is that the publisher agent knows the IDs of the workflows it starts, so it can check the status of the workflows and approve or reject them without being explicitly given the context (instance IDs, etc).
-
-## Key Concepts Demonstrated
-
-The same key concepts as the [05_AgentOrchestration_HITL](../05_AgentOrchestration_HITL) sample are demonstrated, but with the following additional concepts:
-
-- **Long running tools**: Using `DurableAgentContext.Current` to start orchestrations from tool calls
-- **Multi-agent orchestration**: Agents can start and manage workflows that orchestrate other agents
-- **Human-in-the-loop (with delegation)**: The agent acts as an intermediary between the human and the workflow. The human remains in the loop, but delegates to the agent to start the workflow and approve or reject the content.
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/06_LongRunningTools
-dotnet run --framework net10.0
-```
-
-The app will prompt you for input. You can interact with the Publisher agent:
-
-```text
-=== Long Running Tools Sample ===
-Enter a topic for the Publisher agent to write about (or 'exit' to quit):
-
-You: Start a content generation workflow for the topic 'The Future of Artificial Intelligence'
-Publisher: The content generation workflow for the topic "The Future of Artificial Intelligence" has been successfully started, and the instance ID is **6a04276e8d824d8d941e1dc4142cc254**. If you need any further assistance or updates on the workflow, feel free to ask!
-```
-
-Behind the scenes, the publisher agent will:
-
-1. Start the content generation workflow via a tool call
-2. The workflow will generate initial content using the Writer agent and wait for human approval, which will be visible in the terminal
-
-Once the workflow is waiting for human approval, you can send approval or rejection by prompting the publisher agent accordingly.
-
-> [!NOTE]
-> You must press Enter after each message to continue the conversation. The sample is set up this way because the workflow is running in the background and may write to the console asynchronously.
-
-To tell the agent to rewrite the content with feedback, you can prompt it to reject the content with feedback.
-
-```text
-You: Reject the content with feedback: The article needs more technical depth and better examples.
-Publisher: The content has been successfully rejected with the feedback: "The article needs more technical depth and better examples." The workflow will now generate new content based on this feedback.
-```
-
-Once you're satisfied with the content, you can approve it for publishing.
-
-```text
-You: Approve the content
-Publisher: The content has been successfully approved for publishing. If you need any more assistance or have further requests, feel free to let me know!
-```
-
-Once the workflow has completed, you can get the status by prompting the publisher agent to give you the status.
-
-```text
-You: Get the status of the workflow you previously started
-Publisher: The status of the workflow with instance ID **6a04276e8d824d8d941e1dc4142cc254** is as follows:
-
-- **Execution Status:** Completed
-- **Created At:** December 22, 2025, 23:08:13 UTC
-- **Last Updated At:** December 22, 2025, 23:09:59 UTC
-- **Workflow Status:** 
-  - Message: Content published successfully at December 22, 2025, 23:09:59 UTC
-  - Human Feedback: Approved
-```
-
-## Viewing Agent and Orchestration State
-
-You can view the state of both the agent and the orchestrations it starts in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Agents**: View the state of the Publisher agent, including its conversation history and tool call history
-   - **Orchestrations**: View the content generation orchestration instances that were started by the agent via tool calls, including their runtime status, custom status, input, output, and execution history
-
-When the publisher agent starts a workflow, the orchestration instance ID is included in the agent's response. You can use this ID to find the specific orchestration in the dashboard and inspect:
-
-- The orchestration's execution progress
-- When it's waiting for human approval (visible in custom status)
-- The content generation workflow state
-- The WriterAgent state within the orchestration
-
-This demonstrates how agents can manage long-running workflows and how you can monitor both the agent's state and the workflows it orchestrates.

-# Reliable Streaming with Redis
-
-This sample demonstrates how to implement reliable streaming for durable agents using Redis Streams as a message broker. It enables clients to disconnect and reconnect to ongoing agent responses without losing messages, inspired by [OpenAI's background mode](https://platform.openai.com/docs/guides/background) for the Responses API.
-
-## Key Concepts Demonstrated
-
-- **Reliable message delivery**: Agent responses are persisted to Redis Streams, allowing clients to resume from any point
-- **Real-time streaming**: Chunks are printed to stdout as they arrive (like `tail -f`)
-- **Cursor-based resumption**: Each chunk includes an entry ID that can be used to resume the stream
-- **Fire-and-forget agent invocation**: The agent runs in the background while the client streams from Redis
-
-## Environment Setup
-
-See the [README.md](../README.md) file in the parent directory for more information on how to configure the environment, including how to install and run common sample dependencies.
-
-### Additional Requirements: Redis
-
-This sample requires a Redis instance. Start a local Redis instance using Docker:
-
-```bash
-docker run -d --name redis -p 6379:6379 redis:latest
-```
-
-To verify Redis is running:
-
-```bash
-docker ps | grep redis
-```
-
-## Running the Sample
-
-With the environment setup, you can run the sample:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/07_ReliableStreaming
-dotnet run --framework net10.0
-```
-
-The app will prompt you for a travel planning request:
-
-```text
-=== Reliable Streaming Sample ===
-Enter a travel planning request (or 'exit' to quit):
-
-You: Plan a 7-day trip to Tokyo, Japan for next month. Include daily activities, restaurant recommendations, and tips for getting around.
-```
-
-The agent's response will stream to your console in real-time as chunks arrive from Redis:
-
-```text
-Starting new conversation: @dafx-travelplanner@a1b2c3d4e5f67890abcdef1234567890
-Press [Enter] to interrupt the stream.
-
-TravelPlanner: # 7-Day Tokyo Adventure
-
-## Day 1: Arrival and Exploration
-...
-```
-
-### Demonstrating Stream Interruption and Resumption
-
-This is the key feature of reliable streaming. Follow these steps to see it in action:
-
-1. **Start a stream**: Run the app and enter a travel planning request
-2. **Note the conversation ID**: The conversation ID is displayed at the start of the stream (e.g., `Starting new conversation: @dafx-travelplanner@a1b2c3d4e5f67890abcdef1234567890`)
-3. **Interrupt the stream**: While the agent is still generating text, press **`Enter`** to interrupt. The agent continues running in the background - your messages are being saved to Redis.
-4. **Resume the stream**: Press **`Enter`** again to reconnect and resume the stream from the last cursor position. The app will automatically resume from where it left off.
-
-```text
-Starting new conversation: @dafx-travelplanner@a1b2c3d4e5f67890abcdef1234567890
-Press [Enter] to interrupt the stream.
-
-TravelPlanner: # 7-Day Tokyo Adventure
-
-## Day 1: Arrival and Exploration
-[Streaming content...]
-
-[Press Enter to interrupt]
-Stream cancelled. Press [Enter] to reconnect and resume the stream from the last cursor.
-Last cursor: 1734567890123-0
-
-[Press Enter to resume]
-Resuming conversation: @dafx-travelplanner@a1b2c3d4e5f67890abcdef1234567890 from cursor: 1734567890123-0
-
-[Stream continues from where it left off...]
-```
-
-## Viewing Agent State
-
-You can view the state of the agent in the Durable Task Scheduler dashboard:
-
-1. Open your browser and navigate to `http://localhost:8082`
-2. In the dashboard, you can see:
-   - **Agents**: View the state of the TravelPlanner agent, including conversation history and current state
-   - **Orchestrations**: View any orchestrations that may have been triggered by the agent
-
-The conversation ID displayed in the console output (shown as "Starting new conversation: {conversationId}") corresponds to the agent's conversation thread. You can use this to identify the agent in the dashboard and inspect:
-
-- The agent's conversation state
-- Tool calls made by the agent (weather and events lookups)
-- The streaming response state
-
-Note that while the console app streams responses from Redis, the agent state in DTS shows the underlying durable agent execution, including all tool calls and conversation context.

-
-### Data Flow
-
-1. **Client sends prompt**: The console app reads the prompt from stdin and generates a new agent thread.
-
-2. **Agent invoked**: The durable agent is signaled to run the travel planner agent. This is fire-and-forget from the console app's perspective.
-
-3. **Responses captured**: As the agent generates responses, the `RedisStreamResponseHandler` (implementing `IAgentResponseHandler`) extracts the text from each `AgentRunResponseUpdate` and publishes it to a Redis Stream keyed by the agent session's conversation ID.
-
-4. **Client polls Redis**: The console app streams events by polling the Redis Stream and printing chunks to stdout as they arrive.
-
-5. **Resumption**: If the client interrupts the stream (e.g., by pressing Enter in the sample), it can resume from the last cursor position by providing the conversation ID and cursor to the call to resume the stream.
-
-## Message Delivery Guarantees
-
-This sample provides **at-least-once delivery** with the following characteristics:
-
-- **Durability**: Messages are persisted to Redis Streams with configurable TTL (default: 10 minutes).
-- **Ordering**: Messages are delivered in order within a session.
-- **Real-time**: Chunks are printed as soon as they arrive from Redis.
-
-### Important Considerations
-
-- **No exactly-once delivery**: If a client disconnects exactly when receiving a message, it may receive that message again upon resumption. Clients should handle duplicate messages idempotently.
-- **TTL expiration**: Streams expire after the configured TTL. Clients cannot resume streams that have expired.
-- **Redis guarantees**: Redis streams are backed by Redis persistence mechanisms (RDB/AOF). Ensure your Redis instance is configured for durability as needed.
-
-## Configuration
-
-| Environment Variable | Description | Default |
-|---------------------|-------------|---------|
-| `REDIS_CONNECTION_STRING` | Redis connection string | `localhost:6379` |
-| `REDIS_STREAM_TTL_MINUTES` | How long streams are retained after last write | `10` |
-| `AZURE_OPENAI_ENDPOINT` | Azure OpenAI endpoint URL | (required) |
-| `AZURE_OPENAI_DEPLOYMENT` | Azure OpenAI deployment name | (required) |
-| `AZURE_OPENAI_KEY` | API key (optional, uses Azure CLI auth if not set) | (optional) |
-
-## Cleanup
-
-To stop and remove the Redis Docker containers:
-
-```bash
-docker stop redis
-docker rm redis
-```

-# Console App Samples
-
-This directory contains samples for console app hosting of durable agents. These samples use standard I/O (stdin/stdout) for interaction, making them both interactive and scriptable.
-
-- **[01_SingleAgent](01_SingleAgent)**: A sample that demonstrates how to host a single conversational agent in a console app and interact with it via stdin/stdout.
-- **[02_AgentOrchestration_Chaining](02_AgentOrchestration_Chaining)**: A sample that demonstrates how to host a single conversational agent in a console app and invoke it using a durable orchestration.
-- **[03_AgentOrchestration_Concurrency](03_AgentOrchestration_Concurrency)**: A sample that demonstrates how to host multiple agents in a console app and run them concurrently using a durable orchestration.
-- **[04_AgentOrchestration_Conditionals](04_AgentOrchestration_Conditionals)**: A sample that demonstrates how to host multiple agents in a console app and run them sequentially using a durable orchestration with conditionals.
-- **[05_AgentOrchestration_HITL](05_AgentOrchestration_HITL)**: A sample that demonstrates how to implement a human-in-the-loop workflow using durable orchestration, including interactive approval prompts.
-- **[06_LongRunningTools](06_LongRunningTools)**: A sample that demonstrates how agents can start and interact with durable orchestrations from tool calls to enable long-running tool scenarios.
-- **[07_ReliableStreaming](07_ReliableStreaming)**: A sample that demonstrates how to implement reliable streaming for durable agents using Redis Streams, enabling clients to disconnect and reconnect without losing messages.
-
-## Running the Samples
-
-These samples are designed to be run locally in a cloned repository.
-
-### Prerequisites
-
-The following prerequisites are required to run the samples:
-
-- [.NET 10.0 SDK or later](https://dotnet.microsoft.com/download/dotnet)
-- [Azure CLI](https://learn.microsoft.com/cli/azure/install-azure-cli) installed and authenticated (`az login`) or an API key for the Azure OpenAI service
-- [Azure OpenAI Service](https://learn.microsoft.com/azure/ai-services/openai/how-to/create-resource) with a deployed model (gpt-4o-mini or better is recommended)
-- [Durable Task Scheduler](https://learn.microsoft.com/azure/azure-functions/durable/durable-task-scheduler/develop-with-durable-task-scheduler) (local emulator or Azure-hosted)
-- [Docker](https://docs.docker.com/get-docker/) installed if running the Durable Task Scheduler emulator locally
-- [Redis](https://redis.io/) (for sample 07 only) - can be run locally using Docker
-
-### Configuring RBAC Permissions for Azure OpenAI
-
-These samples are configured to use the Azure OpenAI service with RBAC permissions to access the model. You'll need to configure the RBAC permissions for the Azure OpenAI service to allow the console app to access the model.
-
-Below is an example of how to configure the RBAC permissions for the Azure OpenAI service to allow the current user to access the model.
-
-Bash (Linux/macOS/WSL):
-
-```bash
-az role assignment create \
-    --assignee "yourname@contoso.com" \
-    --role "Cognitive Services OpenAI User" \
-    --scope /subscriptions/<your-subscription-id>/resourceGroups/<your-resource-group-name>/providers/Microsoft.CognitiveServices/accounts/<your-openai-resource-name>
-```
-
-PowerShell:
-
-```powershell
-az role assignment create `
-    --assignee "yourname@contoso.com" `
-    --role "Cognitive Services OpenAI User" `
-    --scope /subscriptions/<your-subscription-id>/resourceGroups/<your-resource-group-name>/providers/Microsoft.CognitiveServices/accounts/<your-openai-resource-name>
-```
-
-More information on how to configure RBAC permissions for Azure OpenAI can be found in the [Azure OpenAI documentation](https://learn.microsoft.com/azure/ai-services/openai/how-to/create-resource?pivots=cli).
-
-### Setting an API key for the Azure OpenAI service
-
-As an alternative to configuring Azure RBAC permissions, you can set an API key for the Azure OpenAI service by setting the `AZURE_OPENAI_KEY` environment variable.
-
-Bash (Linux/macOS/WSL):
-
-```bash
-export AZURE_OPENAI_KEY="your-api-key"
-```
-
-PowerShell:
-
-```powershell
-$env:AZURE_OPENAI_KEY="your-api-key"
-```
-
-### Start Durable Task Scheduler
-
-Most samples use the Durable Task Scheduler (DTS) to support hosted agents and durable orchestrations. DTS also allows you to view the status of orchestrations and their inputs and outputs from a web UI.
-
-To run the Durable Task Scheduler locally, you can use the following `docker` command:
-
-```bash
-docker run -d --name dts-emulator -p 8080:8080 -p 8082:8082 mcr.microsoft.com/dts/dts-emulator:latest
-```
-
-The DTS dashboard will be available at `http://localhost:8080`.
-
-### Environment Configuration
-
-Each sample reads configuration from environment variables. You'll need to set the following environment variables:
-
-```bash
-export AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/"
-export AZURE_OPENAI_DEPLOYMENT="your-deployment-name"
-```
-
-### Running the Console Apps
-
-Navigate to the sample directory and run the console app:
-
-```bash
-cd dotnet/samples/DurableAgents/ConsoleApps/01_SingleAgent
-dotnet run --framework net10.0
-```
-
-> [!NOTE]
-> The `--framework` option is required to specify the target framework for the console app because the samples are designed to support multiple target frameworks. If you are using a different target framework, you can specify it with the `--framework` option.
-
-The app will prompt you for input via stdin.
-
-### Viewing the sample output
-
-The console app output is displayed directly in the terminal where you ran `dotnet run`. Agent responses are printed to stdout with subtle color coding for better readability.
-
-You can also see the state of agents and orchestrations in the Durable Task Scheduler dashboard at `http://localhost:8082`.
