How to enable "Application Timeline" for UWP app?
<p>I'm working on a UWP C# app.  I am running the profiling tool in Visual Studio 2015 (Pro Edition) and taking snapshots.  When I open the report the only option enabled is "Memory Usage", but "Application Timeline" is the information that would be useful to me.  </p>

<p>The docs I found say it should be available, but it is always grayed out.  How do I enable?</p>
