Exception thrown: 'System.Exception' in mscorlib.ni.dll on UWP App Start
<p>So when I start my UWP application I briefly get a splash screen and then an exception is thrown at:</p>

<blockquote>
  <p>mscorlib.ni.dll!System.RuntimeTypeHandle.GetTypeByName(string name, bool throwOnError, bool ignoreCase, bool reflectionOnly, ref System.Threading.StackCrawlMark stackMark, System.IntPtr pPrivHostBinder, bool loadTypeFromPartialName)
      mscorlib.ni.dll!System.RuntimeType.GetType(string typeName, bool throwOnError, bool ignoreCase, bool reflectionOnly, ref System.Threading.StackCrawlMark stackMark)
      mscorlib.ni.dll!System.Type.GetType(string typeName, bool throwOnError)

<p>There's no futher details other than "Exception thrown: 'System.Exception' in mscorlib.ni.dll".</p>

<p>Running a different UWP app such as the UWP blank template app works fine but this app specifically seems to have this problem.</p>

<p>I can reproduce the problem with a cut down version of my app that if needed can be <a href="https://www.dropbox.com/s/01euipylowpubux/ReproSample.7z?dl=0" rel="nofollow">downloaded here</a>.</p>
