The Microsoft identity team released a CTP package for WIF back in 2011 adding support for the SAML 2.0 authentication protocol.

Unfortunately the link to the Microsoft Connect site is dead. Since most WIF functionality has been moved into .NET 4.5 System.IdentityModel namespace, I was hoping to find the Saml2AuthenticationModule
class there. However, I cannot find that class anywhere in the identity model assemblies.
Does anyone knows what happened to the SAML 2.0 support classes? Where they migrated to .NET 4.5 System.IdentityModel namespace? If not, is the original CTP package available somewhere?
