My Question is about returning EF entity using WCF service . As wcf required Data Members for returning data. Solution i have to do mapping of entity to WCF data members which is quit hectic. Is there possible solution which reduce my work effort. I tried EntityFramework with WCF - how to return EF entities but available solution have support for vs2010 only.

This is tricky question. You want to pass EF entities through WCF. This is bad in some way, because EF objects are burdened with additional data provided by EF (eg for change tracking purposes). The best way to pass objects through domains in your application is create DTO objects. To do that, you can develop additional mappings (with usage of T4 templates) that create this DTOs based on your existing EF entities.
