Ok, has anyone had this problem or know how to fix it?
I downloaded VS 2010 beta 2 and installed it, I checked it out. But now when I am editing a xaml file in VS 2008 while I have a c# class window open I lose all intellisense on my classes and it show the usings above saying "A type or namespace 'XXXX' could not be found (are you missing a directive or assembly reference?)"
So I have to build my project and then it all comes back.
You can imagine how unnerving this is.
Any insight?
UPDATE: It seems that the only thing affected was a specific project. The weird thing is that I didn't open that project int vs 2010.
I may never figure this one out. :|
