Specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider

I got this error when i was trying to browse the WCF data Services. The resolution for this issue was to define the connection string for database defined in in app.config file to the web.config file of the web application.

In Nutshell , below is my scnerio :

Project 1 : Contains the .edmx and app.config file

Project 2 : Contains the .SVC referencing entity model defined in project 1 and web.config file

Resolution :

Copy the Db connection defined in app.config to web.config under configuration section .
