I have a problem in my ASP.NET project created with Entity Framework. I am trying to create the controller, but when I click Add --> Controller
, fill the fields and press Add, it shows me this error:
I created it as an ASP.NET web application -> .NET Framework 4.7.2 -> Web Forms -> Authentication: Individual User Accounts -> MVC & Web API.
I tried rebuilding the solution, creating back the program and anything worked for me. I hope you can help me.
