title: "Only a single ContentDialog can be open at any time." error while opening another contentdialog
body: <p>I am using <code>Windows.UI.Xaml.Controls.ContentDialog</code> to show a confirmation. And based on the response from the first dialog I would (or would not) show another dialog. But, when I am trying to open the second content dialog it throws : "Only a single ContentDialog can be open at any time." error. Even though in the UI, first dialog would be closed but somehow I am still not able to open the second dialog. Any idea?</p>
