+# Evaluation - Workflow Eval
+
+This sample demonstrates evaluating a multi-agent workflow with per-agent breakdown.
+
+## What this sample demonstrates
+
+- Building a two-agent workflow (planner → executor)
+- Running the workflow and collecting events
+- Using `run.EvaluateAsync()` to evaluate the completed run
+- Per-agent sub-results via `results.SubResults`
+- Combining `FunctionEvaluator.Create` with `EvalChecks.KeywordCheck`
+
+## Prerequisites
+
+- .NET 10 SDK or later
+- Azure CLI installed and authenticated (`az login`)
+
+Set the following environment variables:
+
+```powershell
+$env:AZURE_AI_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project"
+$env:AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
+```
+
+## Run the sample
+
+```powershell
+cd dotnet/samples/03-workflows/Evaluation
+dotnet run --project .\Evaluation_WorkflowEval

-# Hosted-Invocations-EchoAgent
-
-A minimal echo agent hosted as a Foundry Hosted Agent using the **Invocations protocol**. The agent reads the request body as plain text, passes it through a custom `EchoAIAgent`, and writes the echoed text back in the response. No LLM or Azure credentials are required.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
-
-## Configuration
-
-Copy the template:
-
-```bash
-cp .env.example .env
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/invocations/Hosted-Invocations-EchoAgent
-dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-```bash
-curl -X POST http://localhost:8088/invocations \
-  -H "Content-Type: text/plain" \
-  -d "Hello, world!"
-```
-
-Expected response:
-
-```
-Echo: Hello, world!
-```
-
-## Running with Docker
-
-Since this project uses `ProjectReference`, the standard `Dockerfile` cannot resolve dependencies outside this folder. Use `Dockerfile.contributor` which takes a pre-published output.
-
-### 1. Publish for the container runtime (Linux Alpine)
-
-```bash
-dotnet publish -c Debug -f net10.0 -r linux-musl-x64 --self-contained false -o out
-```
-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-invocations-echo-agent .
-```
-
-### 3. Run the container
-
-```bash
-docker run --rm -p 8088:8088 hosted-invocations-echo-agent
-```
-
-### 4. Test it
-
-```bash
-curl -X POST http://localhost:8088/invocations \
-  -H "Content-Type: text/plain" \
-  -d "Hello from Docker!"
-```
-
-## NuGet package users
-
-If you are consuming the Agent Framework as a NuGet package (not building from source), use the standard `Dockerfile` instead of `Dockerfile.contributor`. See the commented section in `Hosted-Invocations-EchoAgent.csproj` for the `PackageReference` alternative.

-# Hosted-ChatClientAgent
-
-A simple general-purpose AI assistant hosted as a Foundry Hosted Agent using the Agent Framework instance hosting pattern. The agent is created inline via `AIProjectClient.AsAIAgent(model, instructions)` and served using the Responses protocol.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a deployed model (e.g., `gpt-4o`)
- Azure CLI logged in (`az login`)
-
-## Configuration
-
-Copy the template and fill in your project endpoint:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env` and set your Azure AI Foundry project endpoint:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-ASPNETCORE_URLS=http://+:8088
-ASPNETCORE_ENVIRONMENT=Development
-AZURE_AI_MODEL_DEPLOYMENT_NAME=gpt-4o
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-ChatClientAgent
-dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "Hello!"
-```
-
-Or with curl (specifying the agent name explicitly):
-
-```bash
-curl -X POST http://localhost:8088/responses \
-  -H "Content-Type: application/json" \
-  -d '{"input": "Hello!", "model": "hosted-chat-client-agent"}'
-```
-
-## Running with Docker
-
-Since this project uses `ProjectReference`, the standard `Dockerfile` cannot resolve dependencies outside this folder. Use `Dockerfile.contributor` which takes a pre-published output.
-
-### 1. Publish for the container runtime (Linux Alpine)
-
-```bash
-dotnet publish -c Debug -f net10.0 -r linux-musl-x64 --self-contained false -o out
-```
-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-chat-client-agent .
-```
-
-### 3. Run the container
-
-Generate a bearer token on your host and pass it to the container:
-
-```bash
-# Generate token (expires in ~1 hour)
-export AZURE_BEARER_TOKEN=$(az account get-access-token --resource https://ai.azure.com --query accessToken -o tsv)
-
-# Run with token
-docker run --rm -p 8088:8088 \
-  -e AGENT_NAME=hosted-chat-client-agent \
-  -e AZURE_BEARER_TOKEN=$AZURE_BEARER_TOKEN \
-  --env-file .env \
-  hosted-chat-client-agent
-```
-
-> **Note:** `AGENT_NAME` is passed via `-e` to simulate the platform injection. `AZURE_BEARER_TOKEN` provides Azure credentials to the container (tokens expire after ~1 hour). The `.env` file provides the remaining configuration.
-
-### 4. Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "Hello!"
-```
-
-Or with curl (specifying the agent name explicitly):
-
-```bash
-curl -X POST http://localhost:8088/responses \
-  -H "Content-Type: application/json" \
-  -d '{"input": "Hello!", "model": "hosted-chat-client-agent"}'
-```
-
-## NuGet package users
-
-If you are consuming the Agent Framework as a NuGet package (not building from source), use the standard `Dockerfile` instead of `Dockerfile.contributor` — it performs a full `dotnet restore` and `dotnet publish` inside the container. See the commented section in `HostedChatClientAgent.csproj` for the `PackageReference` alternative.

-# Hosted-FoundryAgent
-
-A hosted agent that delegates to a **Foundry-managed agent definition**. Instead of defining the model, instructions, and tools inline in code, this sample retrieves an existing agent registered in the Foundry platform via `AIProjectClient.AsAIAgent(agentRecord)` and hosts it using the Responses protocol.
-
-This is the **Foundry hosting** pattern — the agent's behavior is configured in the platform (via Foundry UI, CLI, or API), and this server simply wraps and serves it.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a **registered agent** (created via Foundry UI, CLI, or API)
- Azure CLI logged in (`az login`)
-
-## Configuration
-
-Copy the template and fill in your project endpoint:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env` and set your Azure AI Foundry project endpoint:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-ASPNETCORE_URLS=http://+:8088
-ASPNETCORE_ENVIRONMENT=Development
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-You also need to set `AGENT_NAME` — the name of the Foundry-managed agent to host. This is injected automatically by the Foundry platform when deployed. For local development, pass it as an environment variable.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-FoundryAgent
-AGENT_NAME=<your-agent-name> dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "Hello!"
-```
-
-Or with curl (specifying the agent name explicitly):
-
-```bash
-curl -X POST http://localhost:8088/responses \
-  -H "Content-Type: application/json" \

-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-foundry-agent .
-```
-
-### 3. Run the container
-
-Generate a bearer token on your host and pass it to the container:
-
-```bash
-# Generate token (expires in ~1 hour)
-export AZURE_BEARER_TOKEN=$(az account get-access-token --resource https://ai.azure.com --query accessToken -o tsv)
-
-# Run with token
-docker run --rm -p 8088:8088 \
-  -e AGENT_NAME=<your-agent-name> \
-  -e AZURE_BEARER_TOKEN=$AZURE_BEARER_TOKEN \

-## How it differs from Hosted-ChatClientAgent
-
-| | Hosted-ChatClientAgent | Hosted-FoundryAgent |
-|---|---|---|
-| **Agent definition** | Inline in code (`AsAIAgent(model, instructions)`) | Managed in Foundry platform (`AsAIAgent(agentRecord)`) |
-| **Model/instructions** | Set in `Program.cs` | Set in Foundry UI/CLI/API |
-| **Tools** | Defined in code | Configured in the platform |
-| **Use case** | Full control over agent behavior | Platform-managed agent with centralized config |

-# Hosted-LocalTools
-
-A hosted agent with **local C# function tools** for hotel search. Demonstrates how to define and wire local tools that the LLM can invoke — a key advantage of code-based hosted agents over prompt agents.
-
-The agent specializes in finding hotels in Seattle, with a `GetAvailableHotels` tool that searches a mock hotel database by dates and budget.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a deployed model (e.g., `gpt-4o`)
- Azure CLI logged in (`az login`)
-
-## Configuration
-
-Copy the template and fill in your project endpoint:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env` and set your Azure AI Foundry project endpoint:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-ASPNETCORE_URLS=http://+:8088
-ASPNETCORE_ENVIRONMENT=Development
-AZURE_AI_MODEL_DEPLOYMENT_NAME=gpt-4o
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-LocalTools
-AGENT_NAME=hosted-local-tools dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "Find me a hotel in Seattle for Dec 20-25 under $200/night"
-```
-
-Or with curl:
-
-```bash
-curl -X POST http://localhost:8088/responses \
-  -H "Content-Type: application/json" \
-  -d '{"input": "Find me a hotel in Seattle for Dec 20-25 under $200/night", "model": "hosted-local-tools"}'
-```
-
-## Running with Docker
-
-Since this project uses `ProjectReference`, use `Dockerfile.contributor` which takes a pre-published output.
-
-### 1. Publish for the container runtime (Linux Alpine)
-
-```bash
-dotnet publish -c Debug -f net10.0 -r linux-musl-x64 --self-contained false -o out
-```
-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-local-tools .
-```
-
-### 3. Run the container
-
-Generate a bearer token on your host and pass it to the container:
-
-```bash
-# Generate token (expires in ~1 hour)
-export AZURE_BEARER_TOKEN=$(az account get-access-token --resource https://ai.azure.com --query accessToken -o tsv)
-
-# Run with token
-docker run --rm -p 8088:8088 \
-  -e AGENT_NAME=hosted-local-tools \
-  -e AZURE_BEARER_TOKEN=$AZURE_BEARER_TOKEN \
-  --env-file .env \
-  hosted-local-tools
-```
-
-### 4. Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "What hotels are available in Seattle for next weekend?"
-```
-
-## How local tools work
-
-The agent has a single tool `GetAvailableHotels` defined as a C# method with `[Description]` attributes. The LLM decides when to call it based on the user's request:
-
-| Parameter | Type | Description |
-|-----------|------|-------------|
-| `checkInDate` | string | Check-in date (YYYY-MM-DD) |
-| `checkOutDate` | string | Check-out date (YYYY-MM-DD) |
-| `maxPrice` | int | Max price per night in USD (default: 500) |
-
-The tool searches a mock database of 6 Seattle hotels and returns formatted results with name, location, rating, and pricing.
-
-## NuGet package users
-
-If you are consuming the Agent Framework as a NuGet package (not building from source), use the standard `Dockerfile` instead of `Dockerfile.contributor`. See the commented section in `HostedLocalTools.csproj` for the `PackageReference` alternative.

-# Hosted-McpTools
-
-A hosted agent demonstrating **two layers of MCP (Model Context Protocol) tool integration**:
-
-1. **Client-side MCP (GitHub)** — The agent connects directly to the GitHub MCP server via `McpClient`, discovers tools, and handles tool invocations locally within the agent process.
-
-2. **Server-side MCP (Microsoft Learn)** — The agent declares a `HostedMcpServerTool` which delegates tool discovery and invocation to the LLM provider (Azure OpenAI Responses API). The provider calls the MCP server on behalf of the agent with no local connection needed.
-
-## How the two MCP patterns differ
-
-| | Client-side MCP | Server-side MCP |
-|---|---|---|
-| **Connection** | Agent connects to MCP server directly | LLM provider connects to MCP server |
-| **Tool invocation** | Handled by the agent process | Handled by the Responses API |
-| **Auth** | Agent manages credentials (e.g., GitHub PAT) | Provider manages credentials |
-| **Use case** | Custom/private MCP servers, fine-grained control | Public MCP servers, simpler setup |
-| **Example** | GitHub (`McpClient` + `HttpClientTransport`) | Microsoft Learn (`HostedMcpServerTool`) |
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a deployed model (e.g., `gpt-4o`)
- Azure CLI logged in (`az login`)
- A **GitHub Personal Access Token** (create at https://github.com/settings/tokens)
-
-## Configuration
-
-Copy the template and fill in your values:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env`:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-AZURE_AI_MODEL_DEPLOYMENT_NAME=gpt-4o
-GITHUB_PAT=ghp_your_token_here
-```
-
-## Running directly (contributors)
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-McpTools
-dotnet run
-```
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-# Uses GitHub MCP (client-side)
-azd ai agent invoke --local "Search for the agent-framework repository on GitHub"
-
-# Uses Microsoft Learn MCP (server-side)
-azd ai agent invoke --local "How do I create an Azure storage account using az cli?"
-```
-
-## Running with Docker
-
-### 1. Publish for the container runtime

-# Hosted-TextRag
-
-A hosted agent with **Retrieval Augmented Generation (RAG)** capabilities using `TextSearchProvider`. The agent grounds its answers in product documentation by running a search before each model invocation, then citing the source in its response.
-
-This sample demonstrates how to add knowledge grounding to a hosted agent without requiring an external search index — using a mock search function that can be replaced with Azure AI Search or any other provider.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a deployed model (e.g., `gpt-4o`)
- Azure CLI logged in (`az login`)
-
-## Configuration
-
-Copy the template and fill in your project endpoint:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env` and set your Azure AI Foundry project endpoint:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-ASPNETCORE_URLS=http://+:8088
-ASPNETCORE_ENVIRONMENT=Development
-AZURE_AI_MODEL_DEPLOYMENT_NAME=gpt-4o
-AZURE_BEARER_TOKEN=
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-TextRag
-AGENT_NAME=hosted-text-rag dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "What is your return policy?"
-azd ai agent invoke --local "How long does shipping take?"
-azd ai agent invoke --local "How do I clean my tent?"
-```
-
-Or with curl:
-
-```bash
-curl -X POST http://localhost:8088/responses \
-  -H "Content-Type: application/json" \
-  -d '{"input": "What is your return policy?", "model": "hosted-text-rag"}'
-```
-
-## Running with Docker
-
-Since this project uses `ProjectReference`, use `Dockerfile.contributor` which takes a pre-published output.
-
-### 1. Publish for the container runtime (Linux Alpine)
-
-```bash
-dotnet publish -c Debug -f net10.0 -r linux-musl-x64 --self-contained false -o out
-```
-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-text-rag .
-```
-
-### 3. Run the container
-
-Generate a bearer token on your host and pass it to the container:
-
-```bash
-# Generate token (expires in ~1 hour)
-export AZURE_BEARER_TOKEN=$(az account get-access-token --resource https://ai.azure.com --query accessToken -o tsv)
-
-# Run with token
-docker run --rm -p 8088:8088 \
-  -e AGENT_NAME=hosted-text-rag \
-  -e AZURE_BEARER_TOKEN=$AZURE_BEARER_TOKEN \
-  --env-file .env \
-  hosted-text-rag
-```
-
-### 4. Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "What is your return policy?"
-```
-
-## How RAG works in this sample
-
-The `TextSearchProvider` runs a mock search **before each model invocation**:
-
-| User query contains | Search result injected |
-|---|---|
-| "return" or "refund" | Contoso Outdoors Return Policy |
-| "shipping" | Contoso Outdoors Shipping Guide |
-| "tent" or "fabric" | TrailRunner Tent Care Instructions |
-
-The model receives the search results as additional context and cites the source in its response. In production, replace `MockSearchAsync` with a call to Azure AI Search or your preferred search provider.
-
-## NuGet package users
-
-If you are consuming the Agent Framework as a NuGet package (not building from source), use the standard `Dockerfile` instead of `Dockerfile.contributor`. See the commented section in `HostedTextRag.csproj` for the `PackageReference` alternative.
