Workaround for invalid markup problems when developing for Windows Phone

Every time I open up a Windows Phone Project in Visual Studio 2013 I got a lots of  errors in the XAML markup. The designer shows "Invalid markup" and the error list is long. I found a workaround for this:

  1. Open Configuration Manager for your Visual Studio solution
  2. Change platform for the Windows Phone Project to x86
  3. Build the Project and the errors is gone
  4. Open Configuration Manager again and change back to "Any CPU"

After follow above steps it will work until you start Visual Studio again.
