.NET: Migrate .NET samples to Foundry-first ProjectResponsesClient by alliscode · Pull Request #4394 · microsoft/agent-framework

alliscode · 2026-03-02T16:14:48Z

Switch all non-declarative .NET samples from AzureOpenAIClient (ChatCompletion) and CRUD PersistentAgentsClient patterns to code-first ProjectResponsesClient from Azure.AI.Projects.OpenAI, mirroring the Python Foundry-first approach.

Changes:

01-get-started (6 samples): Rewritten with ProjectResponsesClient + snippet tags
02-agents/Agents (16 samples): AzureOpenAIClient -> ProjectResponsesClient
02-agents/FoundryAgents: 13 duplicates deleted, 8 unique samples migrated to code-first
Other samples (OpenTelemetry, Memory, RAG, Skills): Migrated to ProjectResponsesClient
03-workflows/FoundryAgent: PersistentAgentsClient -> ProjectResponsesClient
Env vars normalized to AZURE_AI_PROJECT_ENDPOINT + AZURE_AI_MODEL_DEPLOYMENT_NAME
READMEs, AGENTS.md, start-demo.ps1 updated; SAMPLE_GUIDELINES.md created

Pull request overview

This PR migrates the .NET samples to a Foundry-first approach by switching from Azure OpenAI ChatCompletions / CRUD agent patterns to code-first ProjectResponsesClient (Azure.AI.Projects.OpenAI) usage, aligning the .NET samples with the Python “Foundry-first” model.

Changes:

Rewires sample clients/agents to use ProjectResponsesClient + IChatClient / ChatClientAgent, and normalizes environment variables to AZURE_AI_PROJECT_ENDPOINT + AZURE_AI_MODEL_DEPLOYMENT_NAME.
Streamlines FoundryAgents samples by deleting duplicates and focusing the folder on Foundry-specific features (server-side tools, lifecycle/evals).
Updates sample docs and adds dotnet/samples/SAMPLE_GUIDELINES.md (including snippet-tag guidance for doc integration).

Switch all .NET samples from model: prefix on AgentReference (which sends 'placeholder' over the wire via MEAI adapter) to ChatOptions.ModelId pattern. Changes: - All 36 sample Program.cs files updated to use ChatClientAgentOptions with ChatOptions.ModelId = deploymentName instead of defaultAgent: new AgentReference(model:deploymentName) - AGENTS.md and SAMPLE_GUIDELINES.md updated with correct code patterns - dotnet format applied to all changed projects Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

+$env:AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
 ```


The AZURE_AI_PROJECT_ENDPOINT example value is missing the /api/projects/<project> path segment required for Foundry project endpoints. With ProjectResponsesClient, using the base host URL will cause requests to target the wrong endpoint.

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

+$env:AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
 ```


The AZURE_AI_PROJECT_ENDPOINT example is a base host URL, but ProjectResponsesClient expects a full Foundry project endpoint including /api/projects/<project>. As written, users following these instructions are likely to configure a non-working endpoint.
