* .NET: Remove Foundry Toolbox server-side tools support Mirrors the Python cleanup in microsoft/agent-framework#5671. Passing toolbox tools as server-side Responses tools is not the experience we want to support; the hosted-agent MCP toolbox path (HostedMcpToolboxAITool + FoundryToolboxService) remains the supported way to consume Foundry Toolboxes. Removed: - FoundryToolbox static class (GetToolboxVersionAsync / GetToolsAsync / ToAITools / SanitizeAndConvert) - AIProjectClient.GetToolboxToolsAsync extension - Agent_Step25_ToolboxServerSideTools sample (+ slnx entry) - FoundryToolboxTests, TestDataUtil, HttpHandlerAssert, and the toolbox JSON fixtures only those tests referenced - ToolboxHostedAgentTests and ToolboxHostedAgentFixture; the "toolbox" switch arm + CreateToolboxAgent helper in TestContainer; matching README scenario row and bootstrap script entry Kept (MCP path, unchanged): - HostedMcpToolboxAITool, FoundryAITool.CreateHostedMcpToolbox, FoundryAIToolExtensions.CreateHostedMcpToolbox(ToolboxRecord/Version) - FoundryToolboxService, AddFoundryToolboxes, marker injection in AgentFrameworkResponseHandler, InputConverter.ReadMcpToolboxMarkers - Hosted-Toolbox sample, McpToolbox* tests, FoundryToolboxServiceTests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Add Foundry Toolbox MCP sample (Agent_Step25_FoundryToolboxMcp) Adds a non-hosted-agent equivalent of the Python foundry_chat_client_with_toolbox.py sample. The agent connects to a Foundry Toolbox's MCP endpoint via Streamable HTTP, injects a fresh Azure AI bearer token on every request, and discovers the toolbox's tools at runtime via McpClient.ListToolsAsync. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * .NET: Tighten Agent_Step25_FoundryToolboxMcp README/Program comments Drop 'non-hosted agent' framing from README (this sample isn't related to hosted agents) and remove narrative comparison to server-side tools from the Program.cs header comment. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Drop python sample reference from Agent_Step25 README Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Drop incorrect .NET 10 prereq from Agent_Step25 README Toolboxes don't require .NET 10 (Microsoft.Agents.AI.Foundry targets net8.0+); the parent AgentsWithFoundry README already lists the sample SDK prereq. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix Toolsets api-version in Agent_Step25 example endpoint Use 2025-05-01-preview to match FoundryToolboxOptions.ApiVersion. The placeholder 'v1' is not accepted by the Toolsets endpoint.

# Getting started with Foundry Agents
|
|
|
|
These samples demonstrate how to use Microsoft Foundry with Agent Framework.
|
|
|
|
## Quick start
|
|
|
|
The simplest way to create a Foundry agent is using the `FoundryAgent` type directly:
|
|
|
|
```csharp
|
|
FoundryAgent agent = new(
|
|
new Uri(endpoint),
|
|
new AzureCliCredential(),
|
|
model: "gpt-5.4-mini",
|
|
instructions: "You are good at telling jokes.",
|
|
name: "JokerAgent");
|
|
|
|
Console.WriteLine(await agent.RunAsync("Tell me a joke about a pirate."));
|
|
```
|
|
|
|
Or using the `AIProjectClient.AsAIAgent(...)` extensions:
|
|
|
|
```csharp
|
|
AIProjectClient aiProjectClient = new(new Uri(endpoint), new DefaultAzureCredential());
|
|
|
|
FoundryAgent agent = aiProjectClient.AsAIAgent(
|
|
model: deploymentName,
|
|
instructions: "You are good at telling jokes.",
|
|
name: "JokerAgent");
|
|
```
|
|
|
|
## Prerequisites
|
|
|
|
- .NET 10 SDK or later
|
|
- Foundry project endpoint
|
|
- Azure CLI installed and authenticated
|
|
|
|
Set:
|
|
|
|
```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-5.4-mini"
|
|
```
|
|
|
|
Some samples require extra tool-specific environment variables. See each sample for details.
