Since //Build 2021 where the Azure Functions OpenAPI extension was officially announced as a preview, it's now GA with the full support of .NET 6.

Because Azure Functions runtime supports both in-proc and out-of-proc .NET 6 worker, this extension also supports both.

Throughout this session, I'm going to discuss how this extension works for both workers, and how you can migrate your existing Function app from .NET Core 3.1 or .NET 5 to .NET 6 with minimal code changes.
