I am having a solution that has two projects - data access layer project and mvc project In data access layer i m using entity framework. and there is a reference to data access layer in mvc project. Now when I run the mvc project it says connection string is not there but it is there in app.config of data access layer project. i tried to copy the connection string and put it in web.config of mvc project but again it was not able to find it. So I gave absolute path of the folder containing csdl, ssdl and msl file from data access layer project to web.config. It is working now. But I want to give a relative path. Please tell me how can I give relative path. I am using EF 6. I tried ./ to the root and ~/ and ../ but nothing is working Regards, Manish
