Please Help me with this problem....

This issue is in the Visual Studio 2012 RTM and Blend for Visual Studio

Answer 1

Try building the application.  If that does not help you might have to do a repair on visual studio 2012

Answer 2

I have tried repairing and reinstalling visual studio but the problem still exists.

Answer 3

Same problem here; After installing the WP8-SDK I get the same message in the designer-window

Edit: Building (and deploying) works - problem exists only in the designer

Answer 4

The CTP of the november-update solves the problem for me:

Answer 5

I also have this issue on VS2012 Pro from my MSDN subscription. I tried repairing my install but no luck. I don't get intellisense with my XAML editor either. Very annoying.

Microsoft, please help.
