Regards Documentation: As a fanboy this is hard to say: While there is documentation for everything, the split between .NET Framework 4.x and .NET Core/.NET 5+ is a tough thing. However, especially in the HTTP land, the namespace give away instantly on any sample (System.Web => .NET Framework vs. Microsoft.AspNetCore => .NET Core/.NET 5+). To speed yourself up when you have previous experience: I think the docs.microsoft.com page is not too bad on that.
