title: VS 2015 RC - Xaml designer won't load when trying to create windows 10 universal apps in Windows 8
body: <p>I've started working on Windows 10 IoT apps, and I'm baffled by the following issue XAML designer won't load when trying to create Windows 10 universal apps in Windows 8 VS 2015 RC. Upon comparing the blank project XAML for Windows 8 applications to the new blank project XAMLfor windows, they appear to be identical.</p>
  
  <p>Except when I double click my Windows 10 Mainpage.xmal I only see the code and the show designer button doesn't do anything.</p>
