It looks like you may be hitting the same error described here: https://developercommunity.visualstudio.com/t/vs-2022-preview-2-the-project-doesnt-know-how-to-r/1491655.

Can you check within the Visual Studio Installer to see if you have "Development tools for .NET". On my Installer it is labeled as "C# and Visual Basic" under the "Development activities"

hi. Keboo.

Are you able to create a new WPF project and have it run?

[TimerOverflow]

oh..
same problem.

Apparently there were no problems when I recently made it with the same template. So I doubted the Material Project. sorry. Apparently there is a problem with my visual studio. thank you
