Greetings,

today before I start working on my application I updated my WinXP. After all updates have been installed my WCF service stop working. There is a following error when I try to open service.svc file in the browser:

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: An error occurred creating the configuration section handler for system.serviceModel/bindings: Could not load type 'System.Security.Authentication.ExtendedProtection.Configuration.ExtendedProtectionPolicyElement' from assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Source Error:

Line 135:               <binding name="MyWSHttpBinding" maxReceivedMessageSize="2147483647">

The colleague of mine tried to run the same service before update and it works fine. He has the same problem after installing updates. Can someone please help me?
