Copilot 7e98b0cd29 .NET: Update HostedAgents samples to Azure.AI.AgentServer.AgentFramework 1.0.0-beta.9 and MEAI 10.3.0 (#4477 )

* Initial plan

* Update HostedAgents samples to Azure.AI.AgentServer.AgentFramework 1.0.0-beta.9 and MEAI 10.3.0

Co-authored-by: rogerbarreto <19890735+rogerbarreto@users.noreply.github.com>

* Fix HostedAgents samples for Microsoft.Agents.AI 1.0.0-rc2 API changes

- Rename CreateAIAgent -> AsAIAgent (AgentThreadAndHITL, AgentWithHostedMCP, AgentWithTextSearchRag)
- Rename AsAgent -> AsAIAgent (AgentsInWorkflows)
- Replace AIContextProviderFactory with AIContextProviders and simplified TextSearchProvider ctor (AgentWithTextSearchRag)
- Update Microsoft.Agents.AI.OpenAI to 1.0.0-rc2 (AgentThreadAndHITL, AgentWithTextSearchRag, AgentWithTools)
- Update Microsoft.Agents.AI.Workflows to 1.0.0-rc2 (AgentsInWorkflows)
- Add Microsoft.Agents.AI 1.0.0-rc2 reference (AgentWithHostedMCP)

* Update HostedAgents samples for beta.9 API changes and add missing projects to slnx

- Use DefaultAzureCredential consistently across all samples
- Add AgentThreadAndHITL, AgentWithLocalTools, AgentWithTools to slnx
- Apply dotnet format

* Remove unnecessary Microsoft.Agents.AI.* package references (transitive from AgentFramework)

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Add DefaultAzureCredential production warning comments to all HostedAgents samples

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Update HostedAgents READMEs to reflect DefaultAzureCredential usage

Replace AzureCliCredential references with DefaultAzureCredential in all
HostedAgents README files to match the actual sample code.

* Replace Microsoft.Extensions.AI.OpenAI with Microsoft.Agents.AI.OpenAI and remove AsIChatClient()

Swap package references from Microsoft.Extensions.AI.OpenAI to
Microsoft.Agents.AI.OpenAI across all 6 HostedAgents samples. This enables
using the AsAIAgent() extension directly on ChatClient/ResponsesClient
(from OpenAI.Chat/OpenAI.Responses namespaces), removing the intermediate
AsIChatClient() call in 3 samples where it was unnecessary.

* Use explicit types and AsAIAgent() extensions across all HostedAgents samples

Replace var with explicit types for clarity in all 6 samples. Replace
new ChatClientAgent() constructor calls with chatClient.AsAIAgent()
extension method in AgentWithLocalTools and AgentsInWorkflows.

What this sample demonstrates

This sample demonstrates how to use Foundry tools with an AI agent via the UseFoundryTools extension. The agent is configured with two tool types: an MCP (Model Context Protocol) connection for fetching Microsoft Learn documentation and a code interpreter for running code when needed.

Key features:

Configuring Foundry tools using UseFoundryTools with MCP and code interpreter
Connecting to an external MCP tool via a Foundry project connection
Using DefaultAzureCredential for Azure authentication
OpenTelemetry instrumentation for both the chat client and agent

For common prerequisites and setup instructions, see the Hosted Agent Samples README.

Prerequisites

In addition to the common prerequisites:

An Azure AI Foundry project with a chat model deployed (e.g., gpt-5.2, gpt-4o-mini)
The Azure AI Developer role assigned on the Foundry resource (includes the agents/write data action required by UseFoundryTools)
An MCP tool connection configured in your Foundry project pointing to https://learn.microsoft.com/api/mcp

Environment Variables

In addition to the common environment variables in the root README:

# Your Azure AI Foundry project endpoint (required by UseFoundryTools)
$env:AZURE_AI_PROJECT_ENDPOINT="https://your-resource.services.ai.azure.com/api/projects/your-project"

# Chat model deployment name (defaults to gpt-4o-mini if not set)
$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"

# The MCP tool connection name (just the name, not the full ARM resource ID)
$env:MCP_TOOL_CONNECTION_ID="SampleMCPTool"

How It Works

An AzureOpenAIClient is created with DefaultAzureCredential and used to get a chat client
The chat client is wrapped with UseFoundryTools which registers two Foundry tool types:
- MCP connection: Connects to an external MCP server (Microsoft Learn) via the project connection name, providing documentation fetch and search capabilities
- Code interpreter: Allows the agent to execute code snippets when needed
UseFoundryTools resolves the connection using AZURE_AI_PROJECT_ENDPOINT internally
A ChatClientAgent is created with instructions guiding it to use the MCP tools for documentation queries
The agent is hosted using RunAIAgentAsync which exposes the OpenAI Responses-compatible API endpoint
