I had blogged about a problem with the new Framework 3.5 SDK installation here . After performing the installation the XAML code editor Intellisense quit working.
I also posted this issue on the SDK Team’s blog. Within an hour of posting on their blog the SDK Team has sprung into action and began working on this issue.
I want to thank Microsoft employees Karin Meier-Magruder, Sean Grimaldi, Chris Hubbard and the rest of the developers who quickly got this issue sorted out and have posted a fix for the problem that you can read here: http://blogs.msdn.com/windowssdk/comments/7850578.aspx
This very simple workaround involves registering one dll using regsvr32. You do not need to repair your Visual Studio 2008 installation.
Have a great day,
Just a grain of sand on the worlds beaches.
