I was surprised with one funny stuff in VS 2008 Team Suite. When you try to get latest version by right-click on solution item in Solution Explorer it use file’s info from project files, not simply listing the TFS directories… So that if you checked out some project file for editing and then someone will add new files in this project to TFS you will never get them until project files isn’t up to date. Of cause this issue is not applicable if you have multiple checkouts switched off. So if you in the same trouble, better use Source Control View from Team Explorer pane and then include new files into the project.
