title: Is RoleProvider not longer available in C# Framework 4.0?
body: <p>I've a Custom <code>RoleProvider</code> created sometime ago, and wanting to change the library to use the .NET Framework 4. Once changed, I am loosing the reference to <code>RoleProvider</code> class. Has something changed since 3.5 for <code>RoleProvider</code>? It seems to have disappeared.</p>
  
  <p>Anyone know the new way to create these in C# 4.0, or do I need to revert back to C# 3.5 and rely on the v2.0 library for <code>System.Web.Security</code>?</p>
  
  <p>Or do I now need to use <code>SqlRoleProvider</code> instead, even though I use a different db than SQL?</p>
