Recursive references in the projects

This is the most stupid thing i have ever seen in development. Few years ago there was a project from the client. Project was live already and required some major changes for it. Customer sent me a source and once i started to work, i found about 5 recursive references like: project1 references to the project2 and project2 references to the project1. This is very big problem with development, it means something wrong with architecture. I have moved required methods to the separate project and it fixed 4 recursive references. But 1 recursive reference still exists. This issue did not allow to compile project. Fix was easy: need to set in the properties of the reference "Copy Local" = false.

Hope this helps!
