The type name 'MembershipProvider' could not be found in the namespace 'System.Web.Security' Upgrade to ASP.NET4

I received this error after upgrading to ASP.NET 4, "The type name 'MembershipProvider' could not be found in the namespace 'System.Web.Security'. This type has been forwarded to assembly 'System.Web.ApplicationServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' Consider adding a reference to that assembly. ASP.NET4."

You wont believe what I did to fix it... I added the reference that it asked for, System.Web.ApplicationServices.

This has happened since MembershipUser and Other Types in the System.Web.Security Namespace Have Been Moved

    Thank you. I was having a tough time tracking this one down. Most online references indicate that it's in System.Web.Security.
