title: VS2010 - How can two or more people edit a use-case file at the same time?
body: <p>I have a solution written in VS2010. I have a modeling project in this solution about use case. What I want is to allow two or more people to be able to edit the file at the same time. Also, I don't want people to overwrite each other. Instead, I'd like VS2010 to merge their changes. Is this possible in VS2010?</p>
