"
+export OPENAI_MODEL="gpt-4.1-mini"
+```
+
+## Running the Sample
+
+### Option 1: Docker Compose (Recommended)
+
+```bash
+cd dotnet/samples/05-end-to-end/AspNetAgentAuthorization
+docker compose up
+```
+
+This starts Keycloak, the AgentService, and the WebClient. Wait for Keycloak to finish importing the realm (you'll see `Running the server` in the logs).
+
+#### Running in GitHub Codespaces
+
+This sample has been built in such a way that it can be run from GitHub Codespaces.
+The Agent Framework repository has a C# specific dev container, named "C# (.NET)", that is configured for Codespaces.
+
+When running in Codespaces, the sample auto-detects the environment via
+`CODESPACE_NAME` and `GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN` and configures
+Keycloak and the web client accordingly. Just make the required ports public:
+
+```bash
+# Make Keycloak and WebClient ports publicly accessible
+gh codespace ports visibility 5002:public 8080:public -c $CODESPACE_NAME
+
+# Start the containers (Codespaces is auto-detected)
+docker compose up
+```
+
+Then open the Codespaces-forwarded URL for port 8080 (shown in the **Ports** tab) in your browser.
+
+### Option 2: Run Locally
+
+1. Start Keycloak:
+ ```bash
+ docker compose up keycloak
+ ```
+
+2. In a new terminal, start the AgentService:
+ ```bash
+ cd Service
+ dotnet run --urls "http://localhost:5001"
+ ```
+
+3. In another terminal, start the WebClient:
+ ```bash
+ cd RazorWebClient
+ dotnet run --urls "http://localhost:8080"
+ ```
+
+## Using the Sample
+
+1. Open `http://localhost:8080` in your browser
+2. Click **Login** — you'll be redirected to Keycloak
+3. Sign in with one of the pre-configured users:
+ - **`testuser` / `password`** — can chat, view expenses, and approve expenses (up to €1,000)
+ - **`viewer` / `password`** — can chat and view expenses, but **cannot approve** them
+4. Try asking the agent:
+ - _"Show me the pending expenses"_ — both users can do this
+ - _"Approve expense #1"_ — only `testuser` can do this; `viewer` will be denied
+ - _"Approve expense #3"_ — even `testuser` will be denied (€4,500 exceeds the €1,000 limit)
+
+## Pre-Configured Keycloak Realm
+
+The `keycloak/dev-realm.json` file auto-provisions:
+
+| Resource | Details |
+|----------|---------|
+| **Realm** | `dev` |
+| **Client: agent-service** | Confidential client (the API audience) |
+| **Client: web-client** | Public client for the Razor app's OIDC login |
+| **Scope: agent.chat** | Required to call the `/chat` endpoint |
+| **Scope: expenses.view** | Required to list pending expenses |
+| **Scope: expenses.approve** | Required to approve expenses |
+| **User: testuser** | Has `agent.chat`, `expenses.view`, and `expenses.approve` scopes |
+| **User: viewer** | Has `agent.chat` and `expenses.view` scopes (no approval) |
+
+### Pre-Seeded Expenses
+
+The service starts with five demo expenses:
+
+| # | Description | Amount | Status |
+|---|-------------|--------|--------|
+| 1 | Conference travel — Berlin | €850 | Pending |
+| 2 | Team dinner — Q4 celebration | €320 | Pending |
+| 3 | Cloud infrastructure — annual renewal | €4,500 | Pending (over limit) |
+| 4 | Office supplies — ergonomic keyboards | €675 | Pending |
+| 5 | Client gift baskets — holiday season | €980 | Pending |
+
+Keycloak admin console: `http://localhost:5002` (login: `admin` / `admin`).
+
+## API Endpoints
+
+### POST /chat (requires `agent.chat` scope)
+
+```bash
+# Get a token for testuser
+TOKEN=$(curl -s -X POST http://localhost:5002/realms/dev/protocol/openid-connect/token \
+ -d "grant_type=password&client_id=web-client&username=testuser&password=password&scope=openid agent.chat expenses.view expenses.approve" \
+ | jq -r '.access_token')
+
+# Chat with the agent
+curl -X POST http://localhost:5001/chat \
+ -H "Authorization: Bearer $TOKEN" \
+ -H "Content-Type: application/json" \
+ -d '{"message": "Show me the pending expenses"}'
+```
+
+## Key Concepts Demonstrated
+
+- **Endpoint-Level Authorization** — The `/chat` endpoint requires the `agent.chat` scope, gating access to the agent itself
+- **Tool-Level Authorization** — Each agent tool checks its own scope (`expenses.view`, `expenses.approve`) at runtime, so different users have different capabilities within the same chat session
+- **Scope-Based Role Mapping** — Keycloak realm roles map to OAuth scopes, allowing administrators to control which users can access which agent capabilities

+# What this sample demonstrates
+
+This sample demonstrates Human-in-the-Loop (HITL) capabilities with thread persistence. The agent wraps function tools with `ApprovalRequiredAIFunction` so that every tool invocation requires explicit user approval before execution. Thread state is maintained across requests using `InMemoryAgentThreadRepository`.
+
+Key features:
+- Requiring human approval before executing function calls
+- Persisting conversation threads across multiple requests
+- Approving or rejecting tool invocations at runtime
+
+> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
+
+## Prerequisites
+
+Before running this sample, ensure you have:
+
+1. .NET 10 SDK installed
+2. An Azure OpenAI endpoint configured
+3. A deployment of a chat model (e.g., gpt-4o-mini)
+4. Azure CLI installed and authenticated (`az login`)
+
+## 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 `ApprovalRequiredAIFunction` to wrap standard AI function tools. When the model decides to call a tool, the wrapper intercepts the invocation and returns a HITL approval request to the caller instead of executing the function immediately.
+
+1. The user sends a message (e.g., "What is the weather in Vancouver?")
+2. The model determines a function call is needed and selects the `GetWeather` tool
+3. `ApprovalRequiredAIFunction` intercepts the call and returns an approval request containing the function name and arguments
+4. The user responds with `approve` or `reject`
+5. If approved, the function executes and the model generates a response using the result
+6. If rejected, the model generates a response without the function result
+
+Thread persistence is handled by `InMemoryAgentThreadRepository`, which stores conversation history keyed by `conversation.id`. This means the HITL flow works across multiple HTTP requests as long as each request includes the same `conversation.id`.
+
+> **Note:** HITL requires a stable `conversation.id` in every request so the agent can correlate the approval response with the original function call. Use the `run-requests.http` file in this directory to test the full approval flow.

+# This sample requires a multi-turn conversation to demonstrate the approval flow:
+# 1. Send a request that triggers a tool call (e.g., asking about the weather)
+# 2. The agent responds with a function_call named "__hosted_agent_adapter_hitl__"
+# containing the call_id and the tool details
+# 3. Send a follow-up request with a function_call_output to approve or reject
+#
+# IMPORTANT: You must use the same conversation.id across all requests in a flow,
+# and update the call_id from step 2 into step 3.

+# What this sample demonstrates
+
+This sample demonstrates how to build a hosted agent that uses local C# function tools — a key advantage of code-based hosted agents over prompt agents. The agent acts as a Seattle travel assistant with a `GetAvailableHotels` tool that simulates querying a hotel availability API.
+
+Key features:
+- Defining local C# functions as agent tools using `AIFunctionFactory`
+- Using `AIProjectClient` to discover the OpenAI connection from the Azure AI Foundry project
+- Building a `ChatClientAgent` with custom instructions and tools
+- Deploying to the Foundry Hosted Agent service
+
+> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
+
+## Prerequisites
+
+Before running this sample, ensure you have:
+
+1. .NET 10 SDK installed
+2. An Azure AI Foundry Project with a chat model deployed (e.g., gpt-4o-mini)
+3. Azure CLI installed and authenticated (`az login`)
+
+## Environment Variables
+
+Set the following environment variables:
+
+```powershell
+# Replace with your Azure AI Foundry project endpoint
+$env:AZURE_AI_PROJECT_ENDPOINT="https://your-project.services.ai.azure.com/api/projects/your-project-name"
+
+# Optional, defaults to gpt-4o-mini
+$env:MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
+```
+
+## How It Works
+
+1. The agent uses `AIProjectClient` to discover the Azure OpenAI connection from the project endpoint
+2. A local C# function `GetAvailableHotels` is registered as a tool using `AIFunctionFactory.Create`
+3. When users ask about hotels, the model invokes the local tool to search simulated hotel data
+4. The tool filters hotels by price and calculates total costs based on the requested dates
+5. Results are returned to the model, which presents them in a conversational format

+# What this sample demonstrates
+
+This sample demonstrates how to use Foundry tools with an AI agent via the `UseFoundryTools` extension. The agent is configured with two tool types: an MCP (Model Context Protocol) connection for fetching Microsoft Learn documentation and a code interpreter for running code when needed.
+
+Key features:
+
+- Configuring Foundry tools using `UseFoundryTools` with MCP and code interpreter
+- Connecting to an external MCP tool via a Foundry project connection
+- Using `AzureCliCredential` for Azure authentication
+- OpenTelemetry instrumentation for both the chat client and agent
+
+> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
+
+## Prerequisites
+
+In addition to the common prerequisites:
+
+1. An **Azure AI Foundry project** with a chat model deployed (e.g., `gpt-5.2`, `gpt-4o-mini`)
+2. The **Azure AI Developer** role assigned on the Foundry resource (includes the `agents/write` data action required by `UseFoundryTools`)
+3. An **MCP tool connection** configured in your Foundry project pointing to `https://learn.microsoft.com/api/mcp`
+
+## Environment Variables
+
+In addition to the common environment variables in the root README:
+
+```powershell
+# Your Azure AI Foundry project endpoint (required by UseFoundryTools)
+$env:AZURE_AI_PROJECT_ENDPOINT="https://your-resource.services.ai.azure.com/api/projects/your-project"
+
+# Chat model deployment name (defaults to gpt-4o-mini if not set)
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
+
+# The MCP tool connection name (just the name, not the full ARM resource ID)
+$env:MCP_TOOL_CONNECTION_ID="SampleMCPTool"
+```
+
+## How It Works
+
+1. An `AzureOpenAIClient` is created with `AzureCliCredential` and used to get a chat client
+2. The chat client is wrapped with `UseFoundryTools` which registers two Foundry tool types:
+ - **MCP connection**: Connects to an external MCP server (Microsoft Learn) via the project connection name, providing documentation fetch and search capabilities
+ - **Code interpreter**: Allows the agent to execute code snippets when needed
+3. `UseFoundryTools` resolves the connection using `AZURE_AI_PROJECT_ENDPOINT` internally
+4. A `ChatClientAgent` is created with instructions guiding it to use the MCP tools for documentation queries
+5. The agent is hosted using `RunAIAgentAsync` which exposes the OpenAI Responses-compatible API endpoint

+# Hosted Agent Samples
+
+These samples demonstrate how to build and host AI agents using the [Azure AI AgentServer SDK](https://learn.microsoft.com/en-us/dotnet/api/overview/azure/ai.agentserver.agentframework-readme). Each sample can be run locally and deployed to Microsoft Foundry as a hosted agent.
+
+## Samples
+
+| Sample | Description |
+|--------|-------------|
+| [`AgentWithTools`](./AgentWithTools/) | Foundry tools (MCP + code interpreter) via `UseFoundryTools` |
+| [`AgentWithLocalTools`](./AgentWithLocalTools/) | Local C# function tool execution (Seattle hotel search) |
+| [`AgentThreadAndHITL`](./AgentThreadAndHITL/) | Human-in-the-loop with `ApprovalRequiredAIFunction` and thread persistence |
+| [`AgentWithHostedMCP`](./AgentWithHostedMCP/) | Hosted MCP server tool (Microsoft Learn search) |
+| [`AgentWithTextSearchRag`](./AgentWithTextSearchRag/) | RAG with `TextSearchProvider` (Contoso Outdoors) |
+| [`AgentsInWorkflows`](./AgentsInWorkflows/) | Sequential workflow pipeline (translation chain) |
+
+## Common Prerequisites
+
+Before running any sample, ensure you have:
+
+1. **.NET 10 SDK** or later — [Download](https://dotnet.microsoft.com/download/dotnet/10.0)
+2. **Azure CLI** installed — [Install guide](https://learn.microsoft.com/cli/azure/install-azure-cli)
+3. **Azure OpenAI** or **Azure AI Foundry project** with a chat model deployed (e.g., `gpt-4o-mini`)
+
+### Authenticate with Azure CLI
+
+All samples use `AzureCliCredential` for authentication. Make sure you're logged in:
+
+```powershell
+az login
+az account show # Verify the correct subscription
+```
+
+### Common Environment Variables
+
+Most samples require one or more of these environment variables:
+
+| Variable | Used By | Description |
+|----------|---------|-------------|
+| `AZURE_OPENAI_ENDPOINT` | Most samples | Your Azure OpenAI resource endpoint URL |
+| `AZURE_OPENAI_DEPLOYMENT_NAME` | Most samples | Chat model deployment name (defaults to `gpt-4o-mini`) |
+| `AZURE_AI_PROJECT_ENDPOINT` | AgentWithTools, AgentWithLocalTools | Azure AI Foundry project endpoint |
+| `MCP_TOOL_CONNECTION_ID` | AgentWithTools | Foundry MCP tool connection name |
+| `MODEL_DEPLOYMENT_NAME` | AgentWithLocalTools | Chat model deployment name (defaults to `gpt-4o-mini`) |
+
+See each sample's README for the specific variables required.
+
+## Azure AI Foundry Setup (for samples that use Foundry)
+
+Some samples (`AgentWithTools`, `AgentWithLocalTools`) connect to an Azure AI Foundry project. If you're using these samples, you'll need additional setup.
+
+### Azure AI Developer Role
+
+The `UseFoundryTools` extension requires the **Azure AI Developer** role on the Cognitive Services resource. Even if you created the project, you may not have this role by default.
+
+```powershell
+az role assignment create `
+ --role "Azure AI Developer" `
+ --assignee "your-email@microsoft.com" `
+ --scope "/subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.CognitiveServices/accounts/{account-name}"
+```
+
+> **Note**: You need **Owner** or **User Access Administrator** permissions on the resource to assign roles. If you don't have this, you may need to request JIT (Just-In-Time) elevated access via [Azure PIM](https://portal.azure.com/#view/Microsoft_Azure_PIMCommon/ActivationMenuBlade/~/aadmigratedresource).
+
+For more details on permissions, see [Azure AI Foundry Permissions](https://aka.ms/FoundryPermissions).
+
+### Creating an MCP Tool Connection
+
+The `AgentWithTools` sample requires an MCP tool connection configured in your Foundry project:
+
+1. Go to the [Azure AI Foundry portal](https://ai.azure.com)
+2. Navigate to your project
+3. Go to **Connected resources** → **+ New connection** → **Model Context Protocol tool**
+4. Fill in:
+ - **Name**: `SampleMCPTool` (or any name you prefer)
+ - **Remote MCP Server endpoint**: `https://learn.microsoft.com/api/mcp`
+ - **Authentication**: `Unauthenticated`
+5. Click **Connect**
+
+The connection **name** (e.g., `SampleMCPTool`) is used as the `MCP_TOOL_CONNECTION_ID` environment variable.
+
+> **Important**: Use only the connection **name**, not the full ARM resource ID.
+
+## Running a Sample
+
+Each sample runs as a standalone hosted agent on `http://localhost:8088/`:
+
+```powershell
+cd
+dotnet run
+```
+
+### Interacting with the Agent
+
+Each sample includes a `run-requests.http` file for testing with the [VS Code REST Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) extension, or you can use PowerShell:
+
+```powershell
+$body = @{ input = "Your question here" } | ConvertTo-Json
+Invoke-RestMethod -Uri "http://localhost:8088/responses" -Method Post -Body $body -ContentType "application/json"
+```
+
+## Deploying to Microsoft Foundry
+
+Each sample includes a `Dockerfile` and `agent.yaml` for deployment. To deploy your agent to Microsoft Foundry, follow the [hosted agents deployment guide](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents).
+
+## Troubleshooting
+
+### `PermissionDenied` — lacks `agents/write` data action
+
+Assign the **Azure AI Developer** role to your user. See [Azure AI Developer Role](#azure-ai-developer-role) above.
+
+### `Project connection ... was not found`
+
+Make sure `MCP_TOOL_CONNECTION_ID` contains only the connection **name** (e.g., `SampleMCPTool`), not the full ARM resource ID path.
+
+### `AZURE_AI_PROJECT_ENDPOINT must be set`
+
+The `UseFoundryTools` extension requires `AZURE_AI_PROJECT_ENDPOINT`. Set it to your Foundry project endpoint (e.g., `https://your-resource.services.ai.azure.com/api/projects/your-project`).
+
+### Multi-framework error when running `dotnet run`
+
+If you see "Your project targets multiple frameworks", specify the framework:
+
+```powershell
+dotnet run --framework net10.0
+```
