Assets file 'D:\a\SharpShell\SharpShell\SharpShell\obj\project.assets.json' doesn't have a target for 'net6.0/win-x64'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project. You may also need to include 'win-x64' in your project's RuntimeIdentifiers.
