Answer 1

A common Error is when you create your Controller File as a class instead of Mvc-/API-Controller file. Even though the code is the same, it won't work.

And make sure you add the Controllers in the startup.cs/program.cs. Example:

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers();
    //or
    services.AddMvc();
}
