What happen to SketchFlow and what we should use instead? : <p>What is the new <strong>Microsoft way</strong> of UI prototyping since VS2015 doesn't support SketchFlow projects.  <em>(I'm having hard time to accept that they removed such a useful tool without providing alternative)</em></p>

<blockquote>
  <p>I know we still have <em>PowerPoint StoryBoards</em> for basic UI mock-ups but I would like to use interactive prototypes through Visual Studio.  <em><strong>Therefore please do not suggest alternative products</strong></em></p>
