c# - How to fix TargetPlatformMinVersion problem in WPF app?

Question

I'm trying to use Windows UI library in my WPF app, and whenever I install Microsoft.UI.Xaml I get the following error.

Microsoft.UI.Xaml nuget package requires TargetPlatformMinVersion >= 10.0.15063.0 (current project is -1)

How to resolve this issue?

My windows SDK version is the latest version downloaded from here.

My OS version is 20H2 and the build number is 19042.685

I tried changing the targeted framework from .NET Core 3, 3.1, and .NET 5.
