* Refactor hosted samples to use AIProjectClient.CreateAIAgentAsync

Replace PersistentAgentsClient and manual AzureOpenAIClient setup with
AIProjectClient.CreateAIAgentAsync() from Microsoft.Agents.AI.AzureAI.

- FoundryMultiAgent: Remove Azure.AI.Agents.Persistent, use CreateAIAgentAsync
  for Writer and Reviewer agents with cleanup in finally block
- FoundrySingleAgent: Remove manual GetConnection/AzureOpenAIClient chain,
  use CreateAIAgentAsync with hotel search tool
- Update csproj: add Microsoft.Agents.AI.AzureAI, remove unused packages

* Update READMEs to reflect AIProjectClient.CreateAIAgentAsync usage

- Reference Microsoft.Agents.AI.AzureAI and Microsoft.Agents.AI.Workflows packages
- Add Azure AI Developer role requirement for agents/write data action
- Replace PersistentAgentsClient references

* Add HostedAgents READMEs and Foundry samples to solution

- Create dotnet/samples/05-end-to-end/HostedAgents/README.md with sample index
- Create python/samples/05-end-to-end/hosted_agents/README.md with sample index
- Add FoundryMultiAgent and FoundrySingleAgent to agent-framework-dotnet.slnx

* Fix Python linting: reorder imports before load_dotenv, remove trailing whitespace

* Update uv.lock to match latest package versions

* Exclude dotnet.microsoft.com from link checker

This domain intermittently times out in CI, causing flaky markdown
link check failures unrelated to PR changes.

* Align env vars to AZURE_AI_PROJECT_ENDPOINT and default model to gpt-4o-mini

Addresses PR review feedback:
- Rename PROJECT_ENDPOINT to AZURE_AI_PROJECT_ENDPOINT across all
  Foundry samples (dotnet + python) to match existing samples
- Change default model from gpt-4.1-mini to gpt-4o-mini consistently

* Skip flaky test CreatesWorkflowEndToEndActivities_WithCorrectName_DefaultAsync

Tracked in #4398

* Remove Python foundry samples from PR scope

Python hosted agent samples need further alignment with the azure-ai
package conventions. Removing from this PR to ship .NET samples first.

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 infererence 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.

Sample Structure

Folder Description
01-get-started/ Progressive tutorial: hello agent → hosting
02-agents/ Deep-dive by concept: tools, middleware, providers, orchestrations
03-workflows/ Workflow patterns: sequential, concurrent, state, declarative
04-hosting/ Deployment: Azure Functions, Durable Tasks, A2A
05-end-to-end/ Full applications, evaluation, demos

Getting Started

Start with 01-get-started/ and work through the numbered files:

  1. 01_hello_agent — Create and run your first agent
  2. 02_add_tools — Add function tools
  3. 03_multi_turn — Multi-turn conversations with AgentSession
  4. 04_memory — Agent memory with AIContextProvider
  5. 05_first_workflow — Build a workflow with executors and edges
  6. 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 AIAgent and can be used with any underlying service that provides an AIAgent implementation.
  • 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.
