Adds support for Foundry Toolsets MCP proxy integration in the hosted agent response handler. Toolsets connect at startup via IHostedService, gating the readiness probe per spec §3.1. MCP tools are injected into every request's ChatOptions and OAuth consent errors (-32006) are intercepted and surfaced as mcp_approval_request + incomplete SSE events. New files: - FoundryToolboxOptions.cs: configuration POCO for toolset names and API version - FoundryToolboxBearerTokenHandler.cs: DelegatingHandler with Azure Bearer token auth, Foundry-Features header injection, and 3x exponential backoff on 429/5xx - McpConsentContext.cs: AsyncLocal-based per-request consent state shared between the tool wrapper and the response handler - ConsentAwareMcpClientTool.cs: AIFunction wrapper that catches -32006 errors and signals consent via shared state and linked CancellationTokenSource - FoundryToolboxService.cs: IHostedService that creates McpClient per toolset at startup and exposes cached tools Modified files: - AgentFrameworkResponseHandler.cs: injects toolbox tools into ChatOptions, sets up linked CTS consent interception, emits mcp_approval_request on -32006 - ServiceCollectionExtensions.cs: adds AddFoundryToolboxes(params string[]) extension - Microsoft.Agents.AI.Foundry.csproj: adds ModelContextProtocol and Azure.Identity dependencies under NETCoreApp condition Sample: - Hosted-Toolbox: minimal hosted agent sample using AddFoundryToolboxes

Get Started with Microsoft Agent Framework for C# Developers
Quickstart
Basic Agent - .NET
using Azure.AI.OpenAI;
using Azure.Identity;
using Microsoft.Agents.AI;
using OpenAI.Responses;
var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")!;
var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME")!;
var agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential())
.GetResponsesClient(deploymentName)
.AsAIAgent(name: "HaikuBot", instructions: "You are an upbeat assistant that writes beautifully.");
Console.WriteLine(await agent.RunAsync("Write a haiku about Microsoft Agent Framework."));
