title: Setting window size on desktop for a Windows 10 UWP app
body: <p>I've just started learning UWP app development on Windows 10 Pro using Visual Studio 2015 Community Edition. I tried to modify the <a href="https://msdn.microsoft.com/library/windows/apps/dn765018.aspx" rel="noreferrer">C# version of the official "Hello, World!" sample</a> by setting the <code>Width</code> and <code>Height</code> attributes of the Page tag in MainPage.xaml.</p>
  
  <p>Interestingly, when I start the app, its size will be different. Moreover, if I resize its window and then restart it, the app seems to remember its previous window size.</p>
  
  <p>Is it possible to force a UWP app to have a predefined window size, at least on desktop PCs?</p>
