My mistake. Thanks for catching that. I just checked in the fix.
There are three different project versions in the tree (.Net3.5SP1/VS2008, 3.5SP1/2010, 4.0/2010). Depending on how I am or anyone else is working on the project the other two versions don't get updated and have sometimes fallen out of sync.
Usually I fix it up right away but I didn't notice this one.
Once Visual Studio 2010 is readily available I'll drop the 2008 version of the project and this won't happen as much anymore.
