title: How to have user prompt dialogs in Windows 8 metro apps?
body: <p>I would like to get some user inputs for my app like Name, DOB, etc from a modal window<br/>
  for this I need a dialog to be displayed which would contain the textboxes and other controls.<br/> 
  Normally in WinForms/WPF I would create a class inherited from the Form/Window class and use the Show/ShowDialog method to present the form to the user <br/>
  How do I achieve this behavior in Windows 8 metro apps using XAML/C# ?<br/>
  I have looked at the <code>MessageDialog</code> class under the <code>Windows.UI.Popups</code> namespace <br/>
  but its for showing only message like the classic MessageBox. <br/>
  I have looked at another <code>CoreWindowFlyout</code> class and also not sure if that can be used for the behavior I am expecting.</p>
