Import VS2019 projects with .NET Core 3.0 Winforms and WPF frameworks

Correction, the NETCoreRuntime setting affects what implicit packages are added by default:

                lPackageNames := case Setting["NETCoreRuntime"]:Value:ToLowerInvariant of
                  "microsoft.netcore.app": new List<String>("Microsoft.NETCore.App.Ref");
                  "microsoft.windowsdesktop.app": new List<String>("Microsoft.NETCore.App.Ref", "Microsoft.WindowsDesktop.App.Ref");
                  "microsoft.aspnetcore.app": new List<String>("Microsoft.NETCore.App.Ref", "Microsoft.ASPNETCore.App.Ref");
                end;

Aside from that, the name goes into the .json files, and its used when debugging to launch the right runtime version. That’s if AFAICT.
