My experience so far of Visual Studio 2022: the good (AI enabled Intellicode, being able to edit and continue during debugging), the bad (some false positive errors, need to revert to Visual Studio 2019 for adding code migrations via Package Manager Console). But overall I like it.

It is relatively easy to remove the use of a Startup.cs file after converting a web project from .NET 5.0 to .NET 6.0. This post shows how I did it.
