title: Is there a way to convert Windows Desktop applications to Universal UWP and Vice Versa?
body: <p>In Visual Studio I am trying to decide which type of application I should start with. I want to make it available to as many devices as I can.</p>
  
  <p>If I make a Windows desktop application (.NET/WPF), I could convert it to a UWP but it only targets desktop applications, which is pointless device-wise.</p>
  
  <p>But if I make a UWP, it would work with Microsoft devices, but not ones running a Windows older than Windows 10. A lot of people still use older versions of Windows, and I would rather make a Windows desktop application than limit the use to a specific version of Windows.</p>
  
  <p>It would also be cool to be able to make it work on other devices like Android.</p>
  
  <p>QUESTIONS: Is there a way to convert a Desktop application to a Universal UWP (with or without the code)? Is there a way to convert a Universal UWP to a Desktop application (or make it run on older Windows machines)? If not, what would be the best application type and why?</p>
  
  <p>Also, is there a different application type I should use instead that I'm not thinking of?</p>
  
  <p>NOTE: Microsoft Project Centennial converts Desktop applications to UWP's, but they only work on desktop machines.</p>
