Edit project file in Visual Studio 2010 using TFS2010

I've got a solution checked out from our TFS2010 system and want to edit the .csproj file itself in native text format (and not via the Project->Properties). Until we introduced TFS2010 I just edited the .csproj file in a simple text editor. How can I edit the project file r开发者_如何学JAVAegarding TFS2010 CheckIn/CheckOut mechanisms?

Many Thanks, Konrad

You can access the project files by right clicking the project in the solution and selecting "Unload Project" then right click on it again and select "Edit MyProject.csproj". To open the project again, right click and select "Reload Project".
