Answer 1

What version of MVC? What version of Visual Studio? Is this an old project or a fresh one.

If it's a relatively new project, it may be easier to create a new shell solution with the authentication you desire - then pull in your models, controllers and views from the old solution.

If it's a VS2013 MVC 5 project, you may be missing the

public partial class Startup

class in your root on the application.

If you create a new empty solution, you can compare what's there and what should be in yours.

HOWEVER.... you need to first read up on Simplemembership....

Deleting all files from bin and then rebuilding the solution worked for me
