set path for code generator in Visual Studio

Question

I set the stringPath to the .edmx file like stringPath = @"Solution\Folder\Model.edmx" It works in one solution but not in another. All the text templating code is the same. In the solution where it doesn't work, it trys to find the file here:

.....Microsoft Visual Studio 10.0\Common7\IDE\Solution\Folder\Model.edmx.

I was wondering what was wrong and how to fix this.

thanks,
