How to show a loading image in UWP?
<p>I am developing an <strong>UWP</strong> application. When user clicks on any control, if that control is taking longer time to execute its tasks I want to show an indication to the user like <strong>Operation is taking a long time, please wait</strong> with Images on the center of the screen.
How can I do that in a UWP aplication? </p>

<p>I think here our UWP is working on Single Thread concept if I am right.<br>
Please give me your suggestion to solve this issue.</p>
