Async Binding Thumbnail Image in UWP
<p>I'm developing internal file manager in my UWP app. I'm showing StorageFolder's content in a GridView with calling this method:</p>

<pre><code>gridView.ItemsSource = await storageFolder.GetItemsAsync();
</code></pre>

<p>Also, I have an item template for visualizing a file/folder item look linked to the the GridView. I have a Image object in this template. I want to bind StorageFolder's thumbnail image to this Image object's <code>Source</code> property. However, <code>GetThumbnailAsync()</code> is an asynchronous method, not a property. How can I do this?</p>
