title: Open UWP app from website
body: <p>Let's start with the background. We are building an app on iOS / Android / Windows where we'll use Firebase Dynamic Links to share content between users (the link looks like this: <a href="https://xya.app.goo.gl?link=.." rel="nofollow noreferrer">https://xya.app.goo.gl?link=..</a>.). On iOS &amp; Android this can launch the app if it is installed or open Play / Store if not installed yet. This also has the advantage of a graceful fallback to our web app. </p>
  
  <p>Now this isn't natively supported on Windows. There are only following options:</p>
  
  <ul>
  <li>Custom URI Schemes (e.g. app://some-link). Not usable because there would be no graceful fallback to our web</li>
  <li>URI handler - since Anniversary Update app can register a handler for regular http URI. Again not usable because we don't own the domain <a href="http://goo.gl" rel="nofollow noreferrer">http://goo.gl</a> which is used for the link</li>
  </ul>
  
  <p>This leads me to only one viable option left - on our web app, detect if user is on Windows. If he is, check if the app is installed and launch it or the Windows Store to let user download it. </p>
  
  <p>Is my thinking correct? If so, how do I launch my app / Store from the web app? It should be possible, it works with Store (when you navigate to Windows Store - e.g. <a href="https://www.microsoft.com/en-gb/store/p/" rel="nofollow noreferrer">https://www.microsoft.com/en-gb/store/p/</a>... - it opens the store app)</p>
  
  <p>Any ideas? I need two thinks - detect if app is installed &amp; launch it</p>
