What are some of the common methods to do simple user validation (account login)?
Also, can you have different authentication schemes per area?
Edit
please go to your model folder when you create a internet application with VS 2010. you will see a cs file there. that file holds a sample structure for User Authentication
Remember that : ASP.NET MVC is not a separate framework. it sits on top of ASP.NET so you can use System.Web.Security.Membership class on MVC as well.
Also, check your Account folder inside your view folder. you will some view samples there.
hope this helps.
