WTL 8.1 and Visual Studio 2010 Premium

I have a weird problem with VS 2010 (Premium).

just reinstalled it
added the WTL library files
installed the WTL wizard
created a "dialog" project via the WTL wizard
compiled and run the skeleton successfully
added a button to the dialog
compilation now fails complaining about undefined symbols (the button IDC_xxx)
turned off pre-compiled headers
cleaned solution, recompiled and run successfully
added the "onClick" handler for the button (just by double clicking on the button, no code added)
compilation fails complaining that CUpdateUI is not defined
clean, reanalyze the solution, etc. doesn't solve the issue

If I manually insert #include's (e.g. atlframe.h for CUpdateUI) I can make it work but this defeat the purpose of using VS2010!

What really annoys me is that I havent touched a single line of code, everything has been done through VS which, I hoped, should have cared for consistency!

Is it my fault? WTL fault? VS Fault? Any suggestion on how I could fix this?

Solution

Ok, solved thanks to the awesomeness of Stack Overflow!

It seems there's a bug in the WTL 8.1 Wizard. It doesn't define the WTL_USE_CPP symbol that is needed to make everything work correctly.
