Today 5 AM, i was looking how i could easily migrate some old VS'2008 solution to the VS'11 Beta for testing.

The common upgrade method worked (devenv.exe /upgrade .sln) BUT.....
I used the several vsprop files a.k.a "Visual Studio Property Sheet" to store several properties relative to my computer. Include path to boost, and all the externals library, framework i used were in those files. But for them the upgrade result was a lit bit surprising.

For  each .vsprop file i used, it create a new one call .prop. They was not empty, but they doesn't really contained what i expected. Both .vsprop and .prop are xml file but they have different syntax & schema.

It look like Visual Studio Dev Team didn't automatically translate the old  format into the new.

But it can be easy to fix. As you can browse for those files through the VS Property editor and add all the include you need, all the specific setting you want and that per configuration. Save those file and if you share them across multiple solution, you do it only one times.

I missed the jump from VS'2008 to 2010 and that change is bit weird, but I suppose it lead to a better per project configuration instead of letting user using the old IDE VC++ folder configuration. It comes more easy to share project and 'build' configuration.
