Roger Barreto de791fb8a9 .Net: Add additional Hosted Agent Samples (#4325)
* Add 3 new hosted agent samples: AgentWithTools, AgentWithLocalTools, AgentThreadAndHITL

- AgentWithTools: Foundry tools (MCP + code interpreter) via UseFoundryTools
- AgentWithLocalTools: Local C# function tool (Seattle hotel search) with AIProjectClient
- AgentThreadAndHITL: Human-in-the-loop with ApprovalRequiredAIFunction and thread persistence

All samples follow agent-framework conventions (net10.0, AzureCliCredential, CPM disabled).
AgentWithTools includes comprehensive README with setup guide and troubleshooting.

* Add root HostedAgents README, replace test_requests.py with .http, update sample READMEs

- Create root README.md with shared prerequisites, Azure AI Foundry setup,
  troubleshooting, and samples index
- Replace test_requests.py with run-requests.http in AgentThreadAndHITL
- Add pointer to root README in all 6 sample READMEs
- Trim AgentWithTools README to concise style

* Fix dotnet format issues in AgentWithLocalTools/Program.cs

- Add UTF-8 BOM (CHARSET)
- Sort System.ClientModel.Primitives import alphabetically (IMPORTS)
- Use target-typed new for AIProjectClient (IDE0090)
- Add internal accessibility modifier to Hotel record (IDE0040)

* Address PR review: align model names and package versions

- Change default model from gpt-4.1-mini to gpt-4o-mini in AgentWithLocalTools
  (Program.cs, agent.yaml, README.md) to match existing samples
- Change README example from gpt-5.2 to gpt-4o-mini in AgentWithTools and root README
- Align AgentWithLocalTools package versions with other samples:
  Azure.AI.AgentServer.AgentFramework beta.6 -> beta.8
  Azure.AI.OpenAI 2.8.0-beta.1 -> 2.7.0-beta.2
  Microsoft.Extensions.AI.OpenAI 10.2.0-preview -> 10.1.1-preview

* Upgrade new samples to latest package versions

- Azure.AI.OpenAI: 2.7.0-beta.2 -> 2.8.0-beta.1
- Microsoft.Extensions.AI.OpenAI: 10.1.1-preview -> 10.3.0

Aligns with AgentWithHostedMCP which uses the latest versions.

* Pin AgentThreadAndHITL to Microsoft.Extensions.AI.OpenAI 10.1.1

Azure.AI.AgentServer.AgentFramework beta.8 was compiled against
Microsoft.Extensions.AI.Abstractions with the single-param
FunctionApprovalRequestContent.CreateResponse(bool). Version 10.3.0
changed the signature to include an optional reason parameter, causing
a binary incompatibility at runtime. Pin to 10.1.1 until the framework
is recompiled against the newer abstractions.

What this sample demonstrates

This sample demonstrates the use of AI agents as executors within a workflow.

This workflow uses three translation agents:

  1. French Agent - translates input text to French
  2. Spanish Agent - translates French text to Spanish
  3. English Agent - translates Spanish text back to English

The agents are connected sequentially, creating a translation chain that demonstrates how AI-powered components can be seamlessly integrated into workflow pipelines.

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

Prerequisites

Before you begin, ensure you have the following prerequisites:

  • .NET 10 SDK or later
  • Azure OpenAI service endpoint and deployment configured
  • Azure CLI installed and authenticated (for Azure credential authentication)

Note: This demo uses Azure CLI credentials for authentication. Make sure you're logged in with az login and have access to the Azure OpenAI resource. For more information, see the Azure CLI documentation.

Set the following environment variables:

$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/" # Replace with your Azure OpenAI resource endpoint
$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
