I recently updated my XP machine now I can't run any of my WCF (.NET 3.5) web apps. It crashes when I call var wsHttpBinding = new WSHttpBinding();
with the following exception:
Could not load type 'System.Security.Authentication.ExtendedProtection.ExtendedProtectionPolicy' from assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
I have read this post but it did not help. There are many posts at Microsoft that do not help either.
