Although i have been through this article http://blog.longle.net/2012/09/25/seeding-users-and-roles-with-mvc4-simplemembershipprovider-simpleroleprovider-ef5-codefirst-and-custom-user-properties/
but i dont know is it correct way to use simple membership provider in asp.net mvc4 application.
Moreover, i want to know what is difference between DefaultMembership provider and SimpleMembership Providers
Please take a look into the following article:
In particular, its on supposedly respectable ASP.NET web portal and the title you looking for is "SimpleMembership: The future of membership for ASP.NET".
The article has all the links you need to get started and have all the answers to your question.
Hope this helps.
