Swagger is Going Away in .NET 9!

Summary

The main theme is the removal of Swagger UI as a built-in feature in .NET 9 templates, impacting developers who rely on this out-of-the-box API documentation tool. While Swashbuckle and alternatives like NSwag are still available as packages, developers must now manually integrate them. The practical takeaway is that developers need to be prepared to add Swagger UI functionality themselves when creating new .NET projects going forward.
