ASP.NET MVC Page Won't Load and says “The resource cannot be found”

Question

I am having a problem where I try to open my ASP.NET MVC application but I get the ASP.NET error page which says this:

Server Error in \'/\' Applicati

Answer 1

I got the same error while building a MVC application.
In my case it happened because I forgot to add the string "Controller" in my controller name.

Error With

public class ProductType : BaseController
{
    public ProductType()
    {
    }
}

Resolved

public class ProductTypeController : BaseController
{
    public ProductTypeController ()
    {
    }
}
