Handling Mixed Mode Assembly Error in WCF Service Host

Being WCF, I feel the 2nd link might prove useful. The config file for WCF Service host is located at C:\Program Files (x86)Microsoft Visual Studio 10.0Common7IDEWcfSvcHost.exe.config and hence making the change in this config file should fix it.

Hope this helps.
