VS2019 New Projects are limited to .Net Core

Question

I'm trying to add a WPF User Control Library to my existing .NET Framework 4.7 Winforms solution to add a little WPF Interoperability. The new project is defaulted to the target framework ".NET Core 3.1" and the only other options are ".NET Core 3.0" and ".NET 5.0". All the other projects in this solution are set to ".NET Framework 4.7" so I think that's why I'm having some issues. Can't I create a new project targeted to ".NET Framework 4.7" even if I can't change a .NET Core project to it? It's the same even if I create a new winforms project.

You should choose WPF User Control Library (.NET Framework) to create WPF User Control Library project which target platform is .NET Framework. In Visual Studio 2019 , it looks like below picture shown:

If you choose WPF User Control Library (.NET) , the new project will target .NET Core platform. It is not recommended to covert .NET Core to .NET Framework, but the reverse conversion is possible, for more details about it, you can refer to the blog: Migrating a Sample WPF App to .NET Core 3 (Part 1)
