title: How to launch a winstore app from within another winstore app
body: <p>I am currently building a win-store app for a client, and I can't seem to figure out how to link to another app from within my current app.</p>
  
  <p>I have seen plenty of documentation on how to open the default application from a URI or file type but nothing on opening a specific app.</p>
  
  <p>Currently I am able to open my app with the function below, after adding a protocol to the declarations in my package.appxmanifest, but this isn't the preferred solution since this will not cause the app to open in full screen.</p>
  
  <pre><code>function openApp() {
  
      var options = new Windows.System.LauncherOptions();
      options.preferredApplicationPackageFamilyName = "packageFamilyName";
      options.preferredApplicationDisplayName = "App Display Name";
  
      var uri = new Windows.Foundation.Uri("linktomyapphere:");
  
  
      Windows.System.Launcher.launchUriAsync(uri).then(
          function (e) {},
          function (err) {
              console.log(err);
          });
  </code></pre>
  
  <p>}</p>
