Agent analysis
The external Microsoft Learn documentation at https://learn.microsoft.com/en-us/agent-framework/agents/providers/azure-openai shows
client.GetResponseClient("gpt-4o-mini")but the correct API (used in all repo samples like dotnet/samples/02-agents/AgentProviders/Agent_With_AzureOpenAIResponses/Program.cs) isclient.GetResponsesClient().AsAIAgent(model: "gpt-4o-mini", ...). The docs source for this page is not in this repository; the fix requires updating the learn.microsoft.com content to use the plural method name without arguments and pass the model to AsAIAgent instead.none1.9.01.9.0[-]Python: .NET: [Bug]: missing method GetResponseClient[/-][+].NET: [Bug]: missing method GetResponseClient[/+]Fix GetResponseClient → GetResponsesClient in Azure OpenAI and OpenAI…
