# What this sample demonstrates
This sample demonstrates a **key advantage of code-based hosted agents**:
- **Multi-agent workflows** - Orchestrate multiple agents working together
Code-based agents can execute **any C# code** you write. This sample includes a Writer-Reviewer workflow where two agents collaborate: a Writer creates content and a Reviewer provides feedback.
The agent is hosted using the [Azure AI AgentServer SDK](https://www.nuget.org/packages/Azure.AI.AgentServer.AgentFramework/) and can be deployed to Microsoft Foundry.
## How It Works
### Multi-Agent Workflow
In [Program.cs](Program.cs), the sample creates two agents using `AIProjectClient.CreateAIAgentAsync()` from the [Microsoft.Agents.AI.AzureAI](https://www.nuget.org/packages/Microsoft.Agents.AI.AzureAI/) package:
- **Writer** - An agent that creates and edits content based on feedback
- **Reviewer** - An agent that provides actionable feedback on the content
The `WorkflowBuilder` from the [Microsoft.Agents.AI.Workflows](https://www.nuget.org/packages/Microsoft.Agents.AI.Workflows/) package connects these agents in a sequential flow:
1. The Writer receives the initial request and generates content
2. The Reviewer evaluates the content and provides feedback
3. Both agent responses are output to the user
### Agent Hosting
The agent is hosted using the [Azure AI AgentServer SDK](https://www.nuget.org/packages/Azure.AI.AgentServer.AgentFramework/),
which provisions a REST API endpoint compatible with the OpenAI Responses protocol.
## Running the Agent Locally
### Prerequisites
Before running this sample, ensure you have:
1. **Azure AI Foundry Project**
- Project created.
- Chat model deployed (e.g., `gpt-4o` or `gpt-4.1`)
- Note your project endpoint URL and model deployment name
> **Note**: You can right-click the project in the Microsoft Foundry VS Code extension and select `Copy Project Endpoint URL` to get the endpoint.
2. **Azure CLI**
- Installed and authenticated
- Run `az login` and verify with `az account show`
- Your identity needs the **Azure AI Developer** role on the Foundry resource (for `agents/write` data action required by `CreateAIAgentAsync`)
3. **.NET 10.0 SDK or later**
- Verify your version: `dotnet --version`
- Download from [https://dotnet.microsoft.com/download](https://dotnet.microsoft.com/download)
### Environment Variables
Set the following environment variables:
**PowerShell:**
```powershell
# Replace with your actual values
$env:AZURE_AI_PROJECT_ENDPOINT="https://<your-resource>.services.ai.azure.com/api/projects/<your-project>"
$env:MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
```
**Bash:**
```bash
export AZURE_AI_PROJECT_ENDPOINT="https://<your-resource>.services.ai.azure.com/api/projects/<your-project>"
export MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
```
### Running the Sample
To run the agent, execute the following command in your terminal:
```bash
dotnet restore
dotnet build
dotnet run
```
This will start the hosted agent locally on `http://localhost:8088/`.
### Interacting with the Agent
**VS Code:**
1. Open the Visual Studio Code Command Palette and execute the `Microsoft Foundry: Open Container Agent Playground Locally` command.
2. Execute the following commands to start the containerized hosted agent.
```bash
dotnet restore
dotnet build
dotnet run
```
3. Submit a request to the agent through the playground interface. For example, you may enter a prompt such as: "Create a slogan for a new electric SUV that is affordable and fun to drive."
4. Review the agent's response in the playground interface.
> **Note**: Open the local playground before starting the container agent to ensure the visualization functions correctly.
**PowerShell (Windows):**
```powershell
$body = @{
input = "Create a slogan for a new electric SUV that is affordable and fun to drive"
stream = $false
} | ConvertTo-Json
Invoke-RestMethod -Uri http://localhost:8088/responses -Method Post -Body $body -ContentType "application/json"
```
**Bash/curl (Linux/macOS):**
```bash
curl -sS -H "Content-Type: application/json" -X POST http://localhost:8088/responses \
-d '{"input": "Create a slogan for a new electric SUV that is affordable and fun to drive","stream":false}'
```
You can also use the `run-requests.http` file in this directory with the VS Code REST Client extension.
The Writer agent will generate content based on your prompt, and the Reviewer agent will provide feedback on the output.
## Deploying the Agent to Microsoft Foundry
**Preparation (required)**
Please check the environment_variables section in [agent.yaml](agent.yaml) and ensure the variables there are set in your target Microsoft Foundry Project.
To deploy the hosted agent:
1. Open the VS Code Command Palette and run the `Microsoft Foundry: Deploy Hosted Agent` command.
2. Follow the interactive deployment prompts. The extension will help you select or create the container files it needs.
3. After deployment completes, the hosted agent appears under the `Hosted Agents (Preview)` section of the extension tree. You can select the agent there to view details and test it using the integrated playground.
**What the deploy flow does for you:**
- Creates or obtains an Azure Container Registry for the target project.
- Builds and pushes a container image from your workspace (the build packages the workspace respecting `.dockerignore`).
- Creates an agent version in Microsoft Foundry using the built image. If a `.env` file exists at the workspace root, the extension will parse it and include its key/value pairs as the hosted agent's environment variables in the create request (these variables will be available to the agent runtime).
- Starts the agent container on the project's capability host. If the capability host is not provisioned, the extension will prompt you to enable it and will guide you through creating it.
## MSI Configuration in the Azure Portal
This sample requires the Microsoft Foundry Project to authenticate using a Managed Identity when running remotely in Azure. Grant the project's managed identity the required permissions by assigning the built-in [Azure AI User](https://aka.ms/foundry-ext-project-role) role.
To configure the Managed Identity:
1. In the Azure Portal, open the Foundry Project.
2. Select "Access control (IAM)" from the left-hand menu.
3. Click "Add" and choose "Add role assignment".
4. In the role selection, search for and select "Azure AI User", then click "Next".
5. For "Assign access to", choose "Managed identity".
6. Click "Select members", locate the managed identity associated with your Foundry Project (you can search by the project name), then click "Select".
7. Click "Review + assign" to complete the assignment.
8. Allow a few minutes for the role assignment to propagate before running the application.

# What this sample demonstrates
This sample demonstrates a **key advantage of code-based hosted agents**:
- **Local C# tool execution** - Run custom C# methods as agent tools
Code-based agents can execute **any C# code** you write. This sample includes a Seattle Hotel Agent with a `GetAvailableHotels` tool that searches for available hotels based on check-in/check-out dates and budget preferences.
The agent is hosted using the [Azure AI AgentServer SDK](https://learn.microsoft.com/en-us/dotnet/api/overview/azure/ai.agentserver.agentframework-readme) and can be deployed to Microsoft Foundry.
## How It Works
### Local Tools Integration
In [Program.cs](Program.cs), the agent uses `AIProjectClient.CreateAIAgentAsync()` from the [Microsoft.Agents.AI.AzureAI](https://www.nuget.org/packages/Microsoft.Agents.AI.AzureAI/) package to create a Foundry agent with a local C# method (`GetAvailableHotels`) that simulates a hotel availability API. This demonstrates how code-based agents can execute custom server-side logic that prompt agents cannot access.
The tool accepts:
- **checkInDate** - Check-in date in YYYY-MM-DD format
- **checkOutDate** - Check-out date in YYYY-MM-DD format
- **maxPrice** - Maximum price per night in USD (optional, defaults to $500)
### Agent Hosting
The agent is hosted using the [Azure AI AgentServer SDK](https://learn.microsoft.com/en-us/dotnet/api/overview/azure/ai.agentserver.agentframework-readme),
which provisions a REST API endpoint compatible with the OpenAI Responses protocol.
## Running the Agent Locally
### Prerequisites
Before running this sample, ensure you have:
1. **Azure AI Foundry Project**
- Project created.
- Chat model deployed (e.g., `gpt-4o` or `gpt-4.1`)
- Note your project endpoint URL and model deployment name
2. **Azure CLI**
- Installed and authenticated
- Run `az login` and verify with `az account show`
- Your identity needs the **Azure AI Developer** role on the Foundry resource (for `agents/write` data action required by `CreateAIAgentAsync`)
3. **.NET 10.0 SDK or later**
- Verify your version: `dotnet --version`
- Download from [https://dotnet.microsoft.com/download](https://dotnet.microsoft.com/download)
### Environment Variables
Set the following environment variables (matching `agent.yaml`):
- `AZURE_AI_PROJECT_ENDPOINT` - Your Azure AI Foundry project endpoint URL (required)
- `MODEL_DEPLOYMENT_NAME` - The deployment name for your chat model (defaults to `gpt-4o-mini`)
**PowerShell:**
```powershell
# Replace with your actual values
$env:AZURE_AI_PROJECT_ENDPOINT="https://<your-resource>.services.ai.azure.com/api/projects/<your-project>"
$env:MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
```
**Bash:**
```bash
export AZURE_AI_PROJECT_ENDPOINT="https://<your-resource>.services.ai.azure.com/api/projects/<your-project>"
export MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
```
### Running the Sample
To run the agent, execute the following command in your terminal:
```bash
dotnet restore
dotnet build
dotnet run
```
This will start the hosted agent locally on `http://localhost:8088/`.
### Interacting with the Agent
**VS Code:**
1. Open the Visual Studio Code Command Palette and execute the `Microsoft Foundry: Open Container Agent Playground Locally` command.
2. Execute the following commands to start the containerized hosted agent.
```bash
dotnet restore
dotnet build
dotnet run
```
3. Submit a request to the agent through the playground interface. For example, you may enter a prompt such as: "I need a hotel in Seattle from 2025-03-15 to 2025-03-18, budget under $200 per night."
4. The agent will use the GetAvailableHotels tool to search for available hotels matching your criteria.
> **Note**: Open the local playground before starting the container agent to ensure the visualization functions correctly.
**PowerShell (Windows):**
```powershell
$body = @{
input = "I need a hotel in Seattle from 2025-03-15 to 2025-03-18, budget under `$200 per night"
stream = $false
} | ConvertTo-Json
Invoke-RestMethod -Uri http://localhost:8088/responses -Method Post -Body $body -ContentType "application/json"
```
**Bash/curl (Linux/macOS):**
```bash
curl -sS -H "Content-Type: application/json" -X POST http://localhost:8088/responses \
-d '{"input": "Find me hotels in Seattle for March 20-23, 2025 under $200 per night","stream":false}'
```
You can also use the `run-requests.http` file in this directory with the VS Code REST Client extension.
The agent will use the `GetAvailableHotels` tool to search for available hotels matching your criteria.
## Deploying the Agent to Microsoft Foundry
**Preparation (required)**
Please check the environment_variables section in [agent.yaml](agent.yaml) and ensure the variables there are set in your target Microsoft Foundry Project.
To deploy the hosted agent:
1. Open the VS Code Command Palette and run the `Microsoft Foundry: Deploy Hosted Agent` command.
2. Follow the interactive deployment prompts. The extension will help you select or create the container files it needs.
3. After deployment completes, the hosted agent appears under the `Hosted Agents (Preview)` section of the extension tree. You can select the agent there to view details and test it using the integrated playground.
**What the deploy flow does for you:**
- Creates or obtains an Azure Container Registry for the target project.
- Builds and pushes a container image from your workspace (the build packages the workspace respecting `.dockerignore`).
- Creates an agent version in Microsoft Foundry using the built image. If a `.env` file exists at the workspace root, the extension will parse it and include its key/value pairs as the hosted agent's environment variables in the create request (these variables will be available to the agent runtime).
- Starts the agent container on the project's capability host. If the capability host is not provisioned, the extension will prompt you to enable it and will guide you through creating it.
## MSI Configuration in the Azure Portal
This sample requires the Microsoft Foundry Project to authenticate using a Managed Identity when running remotely in Azure. Grant the project's managed identity the required permissions by assigning the built-in [Azure AI User](https://aka.ms/foundry-ext-project-role) role.
To configure the Managed Identity:
1. In the Azure Portal, open the Foundry Project.
2. Select "Access control (IAM)" from the left-hand menu.
3. Click "Add" and choose "Add role assignment".
4. In the role selection, search for and select "Azure AI User", then click "Next".
5. For "Assign access to", choose "Managed identity".
6. Click "Select members", locate the managed identity associated with your Foundry Project (you can search by the project name), then click "Select".
7. Click "Review + assign" to complete the assignment.
8. Allow a few minutes for the role assignment to propagate before running the application.
