WCF unhandled exception occured during the excution of the current web request

I have a WCF service that is build in VS2008 When I publish the service and run it in IIS (32 bit applications are enabled in application pool) then fine, it works. But when I try debugging the application (platform targets of all the projects are Any CPU), I get the following error:

Common Language Runtime detected an invalid program.

Description: An unhandled exception occurred during the execution of the current web     request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidProgramException: Common Language Runtime detected an invalid program.

The platform your have for development is 32 bit and the platform on which you deploy is 64 bit. Selecting the debug type AnyCPU assembly will JIT to 64 bit code when loaded into 64 bit process and 32 bit when loaded into a 32 bit process. The published assembly / dependent assembly is most probably not compatible for 64 bit and need to be in 32 bit process.

You can read more about choosing the target platform and its impact over here.
