+# GitHub Copilot Instructions
+
+This repository contains both Python and C# code.
+All python code resides under the `python/` directory.
+All C# code resides under the `dotnet/` directory.
+
+The purpose of the code is to provide a framework for building AI agents.
+
+When contributing to this repository, please follow these guidelines:
+
+## C# Code Guidelines
+
+Here are some general guidelines that apply to all code.
+
+- The top of all *.cs files should have a copyright notice: `// Copyright (c) Microsoft. All rights reserved.`
+- All public methods and classes should have XML documentation comments.
+
+### C# Sample Code Guidelines
+
+Sample code is located in the `dotnet/samples` directory.
+
+When adding a new sample, follow these steps:
+
+- The sample should be a standalone .net project in one of the subdirectories of the samples directory.
+- The directory name should be the same as the project name.
+- The directory should contain a README.md file that explains what the sample does and how to run it.
+- The README.md file should follow the same format as other samples.
+- The csproj file should match the directory name.
+- The csproj file should be configured in the same way as other samples.
+- The project should preferably contain a single Program.cs file that contains all the sample code.
+- The sample should be added to the solution file in the samples directory.
+- The sample should be tested to ensure it works as expected.
+- A reference to the new samples should be added to the README.md file in the parent directory of the new sample.
+
+The sample code should follow these guidelines:
+
+- Configuration settings should be read from environment variables, e.g. `var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT") ?? throw new InvalidOperationException("AZURE_OPENAI_ENDPOINT is not set.");`.
+- Environment variables should use upper snake_case naming convention.
+- Secrets should not be hardcoded in the code or committed to the repository.
+- The code should be well-documented with comments explaining the purpose of each step.
+- The code should be simple and to the point, avoiding unnecessary complexity.
+- Prefer inline literals over constants for values that are not reused. For example, use `new ChatClientAgent(chatClient, instructions: "You are a helpful assistant.")` instead of defining a constant for "instructions".
+- Ensure that all private classes are sealed
+- Use the Async suffix on the name of all async methods that return a Task or ValueTask.
+- Prefer defining variables using types rather than var, to help users understand the types involved.
+- Follow the patterns in the samples in the same directories where new samples are being added.
+- The structure of the sample should be as follows:
+  - The top of the Program.cs should have a copyright notice: `// Copyright (c) Microsoft. All rights reserved.`
+  - Then add a comment describing what the sample is demonstrating.
+  - Then add the necessary using statements.
+  - Then add the main code logic.
+  - Finally, add any helper methods or classes at the bottom of the file.
+
+### C# Unit Test Guidelines
+
+Unit tests are located in the `dotnet/tests` directory in projects with a `.UnitTests.csproj` suffix.
+
+Unit tests should follow these guidelines:
+
+- Use `this.` for accessing class members
+- Add Arrange, Act and Assert comments for each test
+- Ensure that all private classes, that are not subclassed, are sealed
+- Use the Async suffix on the name of all async methods
+- Use the Moq library for mocking objects where possible
+- Validate that each test actually tests the target behavior, e.g. we should not have tests that creates a mock, calls the mock and then verifies that the mock was called, without the target code being involved. We also shouldn't have tests that test language features, e.g. something that the compiler would catch anyway.
+- Avoid adding excessive comments to tests. Instead favour clear easy to understand code.
+- Follow the patterns in the unit tests in the same project or classes to which new tests are being added

+# AG-UI Protocol Support for .NET Agent Framework
+
+## Context and Problem Statement
+
+The .NET Agent Framework needed a standardized way to enable communication between AI agents and user-facing applications with support for streaming, real-time updates, and bidirectional communication. Without AG-UI protocol support, .NET agents could not interoperate with the growing ecosystem of AG-UI-compatible frontends and agent frameworks (LangGraph, CrewAI, Pydantic AI, etc.), limiting the framework's adoption and utility.
+
+The AG-UI (Agent-User Interaction) protocol is an open, lightweight, event-based protocol that addresses key challenges in agentic applications including streaming support for long-running agents, event-driven architecture for nondeterministic behavior, and protocol interoperability that complements MCP (tool/context) and A2A (agent-to-agent) protocols.
+
+## Decision Drivers
+
+- Need for streaming communication between agents and client applications
+- Requirement for protocol interoperability with other AI frameworks
+- Support for long-running, multi-turn conversation sessions
+- Real-time UI updates for nondeterministic agent behavior
+- Standardized approach to agent-to-UI communication
+- Framework abstraction to protect consumers from protocol changes
+
+## Considered Options
+
+1. **Implement AG-UI event types as public API surface** - Expose AG-UI event models directly to consumers
+2. **Use custom AIContent types for lifecycle events** - Create new content types (RunStartedContent, RunFinishedContent, RunErrorContent)
+3. **Current approach** - Internal event types with framework-native abstractions
+
+## Decision Outcome
+
+Chosen option: "Current approach with internal event types and framework-native abstractions", because it:
+
+- Protects consumers from protocol changes by keeping AG-UI events internal
+- Maintains framework abstractions through conversion at boundaries
+- Uses existing framework types (AgentRunResponseUpdate, ChatMessage) for public API
+- Focuses on core text streaming functionality
+- Leverages existing properties (ConversationId, ResponseId, ErrorContent) instead of custom types
+- Provides bidirectional client and server support
+
+### Implementation Details
+
+**In Scope:**
+1. **Client-side AG-UI consumption** (`Microsoft.Agents.AI.AGUI` package)
+   - `AGUIAgent` class for connecting to remote AG-UI servers
+   - `AGUIAgentThread` for managing conversation threads
+   - HTTP/SSE streaming support
+   - Event-to-framework type conversion
+
+2. **Server-side AG-UI hosting** (`Microsoft.Agents.AI.Hosting.AGUI.AspNetCore` package)
+   - `MapAGUIAgent` extension method for ASP.NET Core
+   - Server-Sent Events (SSE) response formatting
+   - Framework-to-event type conversion
+   - Agent factory pattern for per-request instantiation
+
+3. **Text streaming events**
+   - Lifecycle events: `RunStarted`, `RunFinished`, `RunError`
+   - Text message events: `TextMessageStart`, `TextMessageContent`, `TextMessageEnd`
+   - Thread and run ID management via `ConversationId` and `ResponseId`
+
+### Key Design Decisions
+
+1. **Event Models as Internal Types** - AG-UI event types are internal with conversion via extension methods; public API uses the existing types in Microsoft.Extensions.AI as those are the abstractions people are familiar with
+
+2. **No Custom Content Types** - Run lifecycle communicated through existing `ChatResponseUpdate` properties (`ConversationId`, `ResponseId`) and standard `ErrorContent` type
+
+3. **Agent Factory Pattern** - `MapAGUIAgent` uses factory function `(messages) => AIAgent` to allow request-specific agent configuration supporting multi-tenancy
+
+4. **Bidirectional Conversion Architecture** - Symmetric conversion logic in shared namespace compiled into both packages for server (`AgentRunResponseUpdate` → AG-UI events) and client (AG-UI events → `AgentRunResponseUpdate`)
+
+5. **Thread Management** - `AGUIAgentThread` stores only `ThreadId` with thread ID communicated via `ConversationId`; applications manage persistence for parity with other implementations and to be compliant with the protocol. Future extensions will support having the server manage the conversation.
+
+6. **Custom JSON Converter** - Uses custom polymorphic deserialization via `BaseEventJsonConverter` instead of built-in System.Text.Json support to handle AG-UI protocol's flexible discriminator positioning
+
+### Consequences
+
+**Positive:**
+- .NET developers can consume AG-UI servers from any framework
+- .NET agents accessible from any AG-UI-compatible client
+- Standardized streaming communication patterns
+- Protected from protocol changes through internal implementation
+- Symmetric conversion logic between client and server
+- Framework-native public API surface
+
+**Negative:**
+- Custom JSON converter required (internal implementation detail)
+- Shared code uses preprocessor directives (`#if ASPNETCORE`)
+- Additional abstraction layer between protocol and public API
+
+**Neutral:**
+- Initial implementation focused on text streaming
+- Applications responsible for thread persistence

 - Subpackage naming should also follow this, so in principle a package name is `<vendor/folder>-<feature/brand>`, so `google-gemini`, `azure-purview`, `microsoft-copilotstudio`, etc. For smaller vendors, where it's less likely to have a multitude of connectors, we can skip the feature/brand part, so `mem0`, `redis`, etc.
 - For Microsoft services we will have two vendor folders, `azure` and `microsoft`, where `azure` contains all Azure services, while `microsoft` contains other Microsoft services, such as Copilot Studio Agents.

+# AG-UI Client and Server Sample
+
+This sample demonstrates how to use the AG-UI (Agent UI) protocol to enable communication between a client application and a remote agent server. The AG-UI protocol provides a standardized way for clients to interact with AI agents.
+
+## Overview
+
+The demonstration has two components:
+
+1. **AGUIServer** - An ASP.NET Core web server that hosts an AI agent and exposes it via the AG-UI protocol
+2. **AGUIClient** - A console application that connects to the AG-UI server and displays streaming updates
+
+> **Warning**
+> The AG-UI protocol is still under development and changing.
+> We will try to keep these samples updated as the protocol evolves.
+
+## Configuring Environment Variables
+
+Configure the required Azure OpenAI environment variables:
+
+```powershell
+$env:AZURE_OPENAI_ENDPOINT="<<your-model-endpoint>>"
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4.1-mini"
+```
+
+> **Note:** This sample uses `DefaultAzureCredential` for authentication. Make sure you're authenticated with Azure (e.g., via `az login`, Visual Studio, or environment variables).
+
+## Running the Sample
+
+### Step 1: Start the AG-UI Server
+
+```bash
+cd AGUIServer
+dotnet build
+dotnet run --urls "http://localhost:5100"
+```
+
+The server will start and listen on `http://localhost:5100`.
+
+### Step 2: Testing with the REST Client (Optional)
+
+Before running the client, you can test the server using the included `.http` file:
+
+1. Open [./AGUIServer/AGUIServer.http](./AGUIServer/AGUIServer.http) in Visual Studio or VS Code with the REST Client extension
+2. Send a test request to verify the server is working
+3. Observe the server-sent events stream in the response
+
+Sample request:
+```http
+POST http://localhost:5100/
+Content-Type: application/json
+
+{
+  "threadId": "thread_123",
+  "runId": "run_456",
+  "messages": [
+    {
+      "role": "user",
+      "content": "What is the capital of France?"
+    }
+  ],
+  "context": {}
+}
+```
+
+### Step 3: Run the AG-UI Client
+
+In a new terminal window:
+
+```bash
+cd AGUIClient
+dotnet run
+```
+
+Optionally, configure a different server URL:
+
+```powershell
+$env:AGUI_SERVER_URL="http://localhost:5100"
+```
+
+### Step 4: Interact with the Agent
+
+1. The client will connect to the AG-UI server
+2. Enter your message at the prompt
+3. Observe the streaming updates with color-coded output:
+   - **Yellow**: Run started notification showing thread and run IDs
+   - **Cyan**: Agent's text response (streamed character by character)
+   - **Green**: Run finished notification
+   - **Red**: Error messages (if any occur)
+4. Type `:q` or `quit` to exit
+
+## Sample Output
+
+```
+AGUIClient> dotnet run
+info: AGUIClient[0]
+      Connecting to AG-UI server at: http://localhost:5100
+
+User (:q or quit to exit): What is the capital of France?
+
+[Run Started - Thread: thread_abc123, Run: run_xyz789]
+The capital of France is Paris. It is known for its rich history, culture, and iconic landmarks such as the Eiffel Tower and the Louvre Museum.
+[Run Finished - Thread: thread_abc123, Run: run_xyz789]
+
+User (:q or quit to exit): Tell me a fun fact about space
+
+[Run Started - Thread: thread_abc123, Run: run_def456]
+Here's a fun fact: A day on Venus is longer than its year! Venus takes about 243 Earth days to rotate once on its axis, but only about 225 Earth days to orbit the Sun.
+[Run Finished - Thread: thread_abc123, Run: run_def456]
+
+User (:q or quit to exit): :q
+```
+
+## How It Works
+
+### Server Side
+
+The `AGUIServer` uses the `MapAGUI` extension method to expose an agent through the AG-UI protocol:
+
+```csharp
+AIAgent agent = new OpenAIClient(apiKey)
+    .GetChatClient(model)
+    .CreateAIAgent(
+        instructions: "You are a helpful assistant.",
+        name: "AGUIAssistant");
+
+app.MapAGUI("/", agent);
+```
+
+This automatically handles:
+- HTTP POST requests with message payloads
+- Converting agent responses to AG-UI event streams
+- Server-sent events (SSE) formatting
+- Thread and run management
+
+### Client Side
+
+The `AGUIClient` uses the `AGUIChatClient` to connect to the remote server:
+
+```csharp
+using HttpClient httpClient = new();
+var chatClient = new AGUIChatClient(
+    httpClient,
+    endpoint: serverUrl,
+    modelId: "agui-client",
+    jsonSerializerOptions: null);
+
+AIAgent agent = chatClient.CreateAIAgent(
+    instructions: null,
+    name: "agui-client",
+    description: "AG-UI Client Agent",
+    tools: []);
+
+bool isFirstUpdate = true;
+AgentRunResponseUpdate? currentUpdate = null;
+
+await foreach (AgentRunResponseUpdate update in agent.RunStreamingAsync(messages, thread))
+{
+    // First update indicates run started
+    if (isFirstUpdate)
+    {
+        Console.WriteLine($"[Run Started - Thread: {update.ConversationId}, Run: {update.ResponseId}]");
+        isFirstUpdate = false;
+    }
+    
+    currentUpdate = update;
+    
+    foreach (AIContent content in update.Contents)
+    {
+        switch (content)
+        {
+            case TextContent textContent:
+                // Display streaming text
+                Console.Write(textContent.Text);
+                break;
+            case ErrorContent errorContent:
+                // Display error notification
+                Console.WriteLine($"[Error: {errorContent.Message}]");
+                break;
+        }
+    }
+}
+
+// Last update indicates run finished
+if (currentUpdate != null)
+{
+    Console.WriteLine($"\n[Run Finished - Thread: {currentUpdate.ConversationId}, Run: {currentUpdate.ResponseId}]");
+}
+```
+
+The `RunStreamingAsync` method:
+1. Sends messages to the server via HTTP POST
+2. Receives server-sent events (SSE) stream
+3. Parses events into `AgentRunResponseUpdate` objects
+4. Yields updates as they arrive for real-time display
+
+## Key Concepts
+
+- **Thread**: Represents a conversation context that persists across multiple runs (accessed via `ConversationId` property)
+- **Run**: A single execution of the agent for a given set of messages (identified by `ResponseId` property)
+- **AgentRunResponseUpdate**: Contains the response data with:
+  - `ResponseId`: The unique run identifier
+  - `ConversationId`: The thread/conversation identifier
+  - `Contents`: Collection of content items (TextContent, ErrorContent, etc.)
+- **Run Lifecycle**: 
+  - The **first** `AgentRunResponseUpdate` in a run indicates the run has started
+  - Subsequent updates contain streaming content as the agent processes
+  - The **last** `AgentRunResponseUpdate` in a run indicates the run has finished
+  - If an error occurs, the update will contain `ErrorContent`

+# What this sample demonstrates
+
+This sample demonstrates how to use TextSearchProvider to add retrieval augmented generation (RAG) capabilities to an AI agent. The provider runs a search against an external knowledge base before each model invocation and injects the results into the model context.
+
+Key features:
+- Configuring TextSearchProvider with custom search behavior
+- Running searches before AI invocations to provide relevant context
+- Managing conversation memory with a rolling window approach
+- Citing source documents in AI responses
+
+## Prerequisites
+
+Before running this sample, ensure you have:
+
+1. An Azure OpenAI endpoint configured
+2. A deployment of a chat model (e.g., gpt-4o-mini)
+3. Azure CLI installed and authenticated
+
+## Environment Variables
+
+Set the following environment variables:
+
+```powershell
+# Replace with your Azure OpenAI endpoint
+$env:AZURE_OPENAI_ENDPOINT="https://your-openai-resource.openai.azure.com/"
+
+# Optional, defaults to gpt-4o-mini
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
+```
+
+## How It Works
+
+The sample uses a mock search function that demonstrates the RAG pattern:
+
+1. When the user asks a question, the TextSearchProvider intercepts it
+2. The search function looks for relevant documents based on the query
+3. Retrieved documents are injected into the model's context
+4. The AI responds using both its training and the provided context
+5. The agent can cite specific source documents in its answers
+
+The mock search function returns pre-defined snippets for demonstration purposes. In a production scenario, you would replace this with actual searches against your knowledge base (e.g., Azure AI Search, vector database, etc.).

+# What this sample demonstrates
+
+This sample demonstrates the use of AI agents as executors within a workflow.
+
+This workflow uses three translation agents:
+1. French Agent - translates input text to French
+2. Spanish Agent - translates French text to Spanish
+3. English Agent - translates Spanish text back to English
+
+The agents are connected sequentially, creating a translation chain that demonstrates how AI-powered components can be seamlessly integrated into workflow pipelines.
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:

+# What this sample demonstrates
+
+This sample demonstrates how to create an Azure AI Agent with the Deep Research Tool, which leverages the o3-deep-research reasoning model to perform comprehensive research on complex topics.
+
+Key features:
+- Configuring and using the Deep Research Tool with Bing grounding
+- Creating a persistent AI agent with deep research capabilities
+- Executing deep research queries and retrieving results
+
+## Prerequisites
+
+Before running this sample, ensure you have:
+
+1. An Azure AI Foundry project set up
+2. A deep research model deployment (e.g., o3-deep-research)
+3. A model deployment (e.g., gpt-4o)
+4. A Bing Connection configured in your Azure AI Foundry project
+5. Azure CLI installed and authenticated
+
+**Important**: Please visit the following documentation for detailed setup instructions:
+- [Deep Research Tool Documentation](https://aka.ms/agents-deep-research)
+- [Research Tool Setup](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/how-to/tools/deep-research#research-tool-setup)
+
+Pay special attention to the purple `Note` boxes in the Azure documentation.
+
+**Note**: The Bing Connection ID must be from the **project**, not the resource. It has the following format:
+
+```
+/subscriptions/<sub_id>/resourceGroups/<rg_name>/providers/<provider_name>/accounts/<account_name>/projects/<project_name>/connections/<connection_name>
+```
+
+## Environment Variables
+
+Set the following environment variables:
+
+```powershell
+# Replace with your Azure AI Foundry project endpoint
+$env:AZURE_FOUNDRY_PROJECT_ENDPOINT="https://your-project.services.ai.azure.com/"
+
+# Replace with your Bing connection ID from the project
+$env:BING_CONNECTION_ID="/subscriptions/.../connections/your-bing-connection"
+
+# Optional, defaults to o3-deep-research
+$env:AZURE_FOUNDRY_PROJECT_DEEP_RESEARCH_DEPLOYMENT_NAME="o3-deep-research"
+
+# Optional, defaults to gpt-4o
+$env:AZURE_FOUNDRY_PROJECT_DEPLOYMENT_NAME="gpt-4o"

+# Agent Framework Retrieval Augmented Generation (RAG) with an external Vector Store with a custom schema
+
+This sample demonstrates how to create and run an agent that uses Retrieval Augmented Generation (RAG) with an external vector store.
+It also uses a custom schema for the documents stored in the vector store.
+This sample uses Qdrant for the vector store, but this can easily be swapped out for any vector store that has a Microsoft.Extensions.VectorStore implementation.
+
+## Prerequisites
+
+- .NET 8.0 SDK or later
+- Azure OpenAI service endpoint
+- Both a chat completion and embedding deployment configured in the Azure OpenAI resource
+- Azure CLI installed and authenticated (for Azure credential authentication)
+- User has the `Cognitive Services OpenAI Contributor` role for the Azure OpenAI resource.
+- An existing Qdrant instance. You can use a managed service or run a local instance using Docker, but the sample assumes the instance is running locally.
+
+**Note**: These samples use Azure OpenAI models. For more information, see [how to deploy Azure OpenAI models with Azure AI Foundry](https://learn.microsoft.com/en-us/azure/ai-foundry/how-to/deploy-models-openai).
+
+**Note**: These samples use Azure CLI credentials for authentication. Make sure you're logged in with `az login` and have access to the Azure OpenAI resource and have the `Cognitive Services OpenAI Contributor` role. For more information, see the [Azure CLI documentation](https://learn.microsoft.com/cli/azure/authenticate-azure-cli-interactively).
+
+## Running the sample from the console
+
+Set the following environment variables:
+
+```powershell
+$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/" # Replace with your Azure OpenAI resource endpoint
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
+$env:AZURE_OPENAI_EMBEDDING_DEPLOYMENT_NAME="text-embedding-3-large"  # Optional, defaults to text-embedding-3-large
+```
+
+If the variables are not set, you will be prompted for the values when running the samples.
+
+To use Qdrant in docker locally, start your Qdrant instance using the default port mappings.
+
+```powershell
+docker run -d --name qdrant -p 6333:6333 -p 6334:6334 qdrant/qdrant:latest
+```
+
+Execute the following command to build the sample:
+
+```powershell
+dotnet build
+```
+
+Execute the following command to run the sample:
+
+```powershell
+dotnet run --no-build
+```
+
+Or just build and run in one step:
+
+```powershell
+dotnet run
+```
+
+## Running the sample from Visual Studio
+
+Open the solution in Visual Studio and set the sample project as the startup project. Then, run the project using the built-in debugger or by pressing `F5`.
+
+You will be prompted for any required environment variables if they are not already set.
