Update Windows 後出現 WCF service errors...

一向 develop 緊既一個 project 今日突然唔work
出左呢個 error...

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'.

由於今日改左唔少野, 所以一時之間都唔知咩事
no idea 之下, google search 一下
立即就知咩事

原來係因為朝早install 左一埋windows update
其中一個update patch 影響到
只要uninstall 左 KB976769v2, reboot 一下, 就解決了~ :)

在此筆記一下, 希望 M$ 快d slove 呢個問題
