This one was driving me crazy for at least a few hours. On a fresh install of VS2008 & Silverlight 3 tools, there was no xaml code highlighting at all, no intellisense, nothing – just like any ordinary text file. Checking the same project on another machine, it was all fine. So I starting disabling/uninstalling all VS plugins (ReSharper, AnkhSVN), but still no luck. Was starting to think I’d have to reinstall VS…
The solution was simple enough – run the VS Command Prompt, and enter:
devenv /resetskippkgs
Problem solved. Apparently a good one to try whenever you lose formatting or Intellisense features.
