Code version tool Subversion might show various version conflicts if you use the repository on multiple machines. This can even happen if no code is changed. In this case it can be quite annoying, as it does not make any sense for the user.
Add the following files or directories to the Subversion Ignore List:
„Bin“ and „obj“ directories only contain the generated .exe files and compilation data, which is regenerated on every rebuild of the project.
The .suo files also do not contain important project data, but change every time you e.g. load the solution and open a .cs file etc.
