Anyone have example C# using QueuedTask.UIScheduler? I have a lot of code that is running in worker thread using QueuedTask.Run but need to somehow dispatch a call to update the gui in the middle of it all. Any examples using UIScheduler or C# .Net would be great.

Arwen,

You can use BeginInvoke to execute on the UI thread.

    <SPAN class="keyword token">private</SPAN> <SPAN class="keyword token">void</SPAN> <SPAN class="token function">onLayersAddRem</SPAN><SPAN class="punctuation token">(</SPAN>LayerEventsArgs obj<SPAN class="punctuation token">)</SPAN>
    <SPAN class="punctuation token">{</SPAN>
      <SPAN class="comment token">//regenerate snaplist when layers are added or removed</SPAN>
      <SPAN class="comment token">//run on UI Thread to sync layersadded event (which runs on background)</SPAN>

    <SPAN class="punctuation token">}</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

In this example I am updating a datagrid in a dockpane from the background thread.
