I started writing an application for Windows Phone marketplace, at the time only making sure that the name I gave it wasn't being used by any other app on the marketplace. I just found out that the same name is being used by a, seemingly popular, SourceForge project. Is this a problem? I haven't released my app yet so I could rename it, but I really like the name and would prefer not to unless it is an issue.

I think that you'd probably be safest finding a new name, though if your app and the sourceforge one are sufficiently different that no connection is implied, then I think it'd be alright. Unless the Sourceforge app is trademarked or something like that. In that case you'd definitely want to rename your app.
