Caliburn.Micro: Async/Await

Caliburn.Micro always had the concept of Coroutines which allowed you to write asynchronous code in a synchronous way.

	using System.Collections.Generic;
	public class ScreenOneViewModel
	{
	public IEnumerable<IResult> GoForward()
	{
	yield return Loader.Show("Downloading...");
	yield return new LoadCatalog("Caliburn.Micro.Coroutines.External.xap");
	yield return Loader.Hide();
	yield return new ShowScreen("ExternalScreen");
	}
	}

Starting from .NET 4.5 with the introduction of the async and await keywords, Microsoft introduced the concept of Coroutines in the language itself.

So if you want to use the same code in Caliburn.Micro with the async syntax, it becomes:

	using System.Collections.Generic;
	public class ScreenOneViewModel
	{
	public async Task GoForward()
	{
	await Loader.Show("Downloading...");
	await new LoadCatalog("Caliburn.Micro.Coroutines.External.xap").LoadAsync();
	await Loader.Hide();
	await ShowScreen("ExternalScreen");
	}
	}
