I am trying to create a Windows C# Desktop application.

Any time I attempt to run /debug it I get a "ResolvePackageAssets" error.

I tried with VB.Net and got the same error. I am running Windows10, VS2019 and 2022, Visual Studio Community edition. I have tried targeting .NET versions 5,6, and 8. Version 8 won't display a forms designer.

I know I am doing something drastically wrong. I would appreciate it if you could give me a clue.

What I have tried:

I have reviewed ALL Microsoft help and learn files and couldn't find a mention of the error. I used NuGet Package Manager to download the .NET versions I did not have and tried them with the same result.

I searched my Murach C# book with no success.
