Hi all, I'm curious about the KnownType attribute, and when to use it--I'm not terribly clear, after reading the MSDN reference.

Ok, I've come a long way in my quest to authenticate WCF invokers against AD LDS, right now I have ActiveDirectoryMembershipProvider set up so that even the VS2010 Project/ASP.NET configuration tool allows me to create and edit AD LDS users, and does so using a Secure connection (so no username/password needed in web.config), so far so g...

As my hosting provider doesn't support .NET 4, I'm forced to implement that functionality in .NET 3.5. How can I rework the code (which I have re...
