xaml syntax coloring is not working after installing visual studio 2012

I am facing this issue after installing VS 2012. By some reason XAML editor in VS2012 doesn't show any syntax highlighting. It is just showing black text and even comments are not coming in green.

Its very difficult to understand xaml without syntax highlighting. If you are also facing this issue then below command might help you to fix this issue.

go to run -> type -> devenv /resetuserdata

then press enter.

It will fix the XAML highlighting issue.
