C# method "Dispatcher.BeginInvoke" in Windows Phone 8.1 Universal App?

Question

Hello,

I am trying to use the method "Dispatcher.BeginInvoke" in a Windows Phone 8.1 Universal App.

However, "Dispatcher.BeginInvoke" seems not to be existing!

"using System.Windows.Threading;" also does not exist!

I get the error message that the namesepace does not exist and I may be missing a reference assembly.

What shall I do?

I remember that I used this method in past when developing a Windows Phone 8.0 Project with VS 2013.

Now I have VS 2015 RC and a Windows 8.1 Universal App Project (but I am developing the Windows Phone 8.1 part of the project).


What is wrong?

Thanks for any hints!

Best wishes,
Miro

It's similar, but different.

https://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.core.coredispatcher.runasync.aspx?f=255&MSPPError=-2147217396

var dispatcher = Windows.UI.Core.CoreWindow.GetForCurrentThread().Dispatcher;
var ignored = dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
   {
         // update on ui thread
   });

Hope that helps.
