I have a solution, made up of more than one project, and I have 2 copies of the projects. in one, everything works, in the other, which is identical (using winmerge) it does not work. and it's completely the same. although when run the dll files comes different, but that's because of the time probably. when the projects are swapped in the solution itself it does not work any way.
What should I do? I feel hopeless. I need the one that is not working to work.
