MembershipProvider in .NET 4.0

Question

How can I add the MembershipProvider class to my .NET 4.0 project in VS 2010 B2?

I want to customize a MembershipProvider, but I cannot without adding this class. Please

Answer 1

The MembershipProvider abstract class is part of the System.Web.ApplicationServices namespace in the .net 4.0 Framework. Add a reference to that assembly and it should solve the issue.
