Like the title says, we upgraded our VS2008 solution to VS2010 and checked in the updated solution file to SVN. When I update my local SVN with the changes, and open the solution in VS2010, I still get the “upgrade wizard” prompt telling me the solution needs to be upgraded to VS2010 even though the .sln file has already been upgraded. Trying to open it back in VS2008 gives the expected error that the solution is for a newer version of Visual Studio.

Any idea what is causing this and how to fix it so we don’t have to run the upgrade wizard on a solution that’s already been upgraded?

    I am not sure this is the root of your problem, but it is worth trying.
    When a VS2008 project is converted by the wizard (when you convert a solution, the projects get converted as well), a file is created for each project file, with the same name but a different extension: vcxproj instead of vcproj. This file is not versioned by the SVN (since it didn’t exist before the wizard did his thing), so it is missing when you SVN-update your solution on the computer where the wizard didn’t run.

    So, add and commit to the SVN repository all the vcxproj files that were created by the wizard, update the other working copy, and try opening the solution again in VS2010. Btw, the old vcproj files are not needed anymore, so you can remove them from the SVN repository if you are sure no one will need the VS2008 version.
