Calling a WCF Service from SQL CLR Stored Procedure

I have created a SQL CLR Stored Procedure which will call a WCF Service. I have managed to get all the correct DLL's loaded into SQL Server to get this to work however I now have following error message:

System.Configuration.Configur开发者_运维问答ationErrorsException: An error occurred creating the configuration section handler for system.serviceModel/extensions: Could not load file or assembly 'System.IdentityModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

I found this posting on the web but I don't know how to update the GAC or whether its actually the fix for the problem: (Invoking a WCF Service from a CLR Trigger)

Look at Niels Berglund's blog post: http://nielsb.wordpress.com/sqlclrwcf/ You can remove the offending line from the machine.config file, or disable the debugging of WCF on the machine with vsdiag_regwcf.exe -u. You will have to recycle SQL once you make the .config file change so that it rejits the app domains.
