title: Error with no line number Cannot find type System.ComponentModel.TypeDescriptionProvider in module System.dll
body: <p>Having an working Univeral solution written in Visual Studio 2013 C#/XAML for WP 8.1 and Windows Store 8.1. Following pretty much Jerry Nixon and Daren may's MVA "Developing Universal Windows Apps with C# and XAML" best practices.</p>
  
  <p>I'm now all of a sudden getting this not trackable compiling error "Cannot find type System.ComponentModel.TypeDescriptionProvider in module System.dll". It only affects WP8.1 and not the Windows Store app which still compiles and runs.</p>
  
  <p>What to do or looking for?</p>
