Hi MMGhoreishi,

Welcome to the MSDN forum.

What’s your VS version and the project type? If you create a new project and add this controller type, does this issue persists or not.

For the error message, if often relates to the inappropriate target framework of the projects or go to Tools -> Options -> Nuget Package Manager ->Package Manager Setting-> General -> Clear All Nuget Cache(s). If your solution has multiple, please check their target framework and make sure are the same version, clean and rebuilt the solution, then add new controller.

Best regards,

Sara
