* .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.

Agent Framework Samples
The agent framework samples are designed to help you get started with building AI-powered agents from various providers.
The Agent Framework supports building agents using various inference and inference-style services.
All these are supported using the single ChatClientAgent class.
The Agent Framework also supports creating proxy agents, that allow accessing remote agents as if they
were local agents. These are supported using various AIAgent subclasses.

Getting Started
Start with 01-get-started/ and work through the numbered files:
- 01_hello_agent — Create and run your first agent
- 02_add_tools — Add function tools
- 03_multi_turn — Multi-turn conversations with
AgentSession - 04_memory — Agent memory with
AIContextProvider - 05_first_workflow — Build a workflow with executors and edges
- 06_host_your_agent — Host your agent via Azure Functions
Additional Samples
Some additional samples of note include:
- Agents: Basic steps to get started with the agent framework.
These samples demonstrate the fundamental concepts and functionalities of the agent framework when using the
AIAgentand can be used with any underlying service that provides anAIAgentimplementation. - Agent Providers: Shows how to create an AIAgent instance for a selection of providers.
- Agent Telemetry: Demo which showcases the integration of OpenTelemetry with the Microsoft Agent Framework using Azure OpenAI and .NET Aspire Dashboard for telemetry visualization.
- Durable Agents - Azure Functions: Samples for using the Microsoft Agent Framework with Azure Functions via the durable task extension.
- Durable Agents - Console Apps: Samples demonstrating durable agents in console applications.
Migration from Semantic Kernel
If you are migrating from Semantic Kernel to the Microsoft Agent Framework, the following resources provide guidance and side-by-side examples to help you transition your existing agents, tools, and orchestration patterns.
The migration samples map Semantic Kernel primitives (such as ChatCompletionAgent and Team orchestrations) to their Agent Framework equivalents (such as ChatClientAgent and workflow builders).
For an in-depth migration guide, see the official migration documentation.
Prerequisites
For prerequisites see each set of samples for their specific requirements.
