Silverlight Testing Using async await syntax

Hello All,
This is gonna be my first blog post. I intend to blog a bit when I’ve something intresting to share about coding, mostly in C#.
Recently I came a cross an interesting post on the blog of ayende about testing in silverlight. When testing code which makes asynchronous calls microsoft gave us the enqueuecallback method shown below.

 1 [TestMethod]        
 2 [Asynchronous]        
 3 public void OldWay()        
 4 {            
 5     var something = SomeTestTask.DoSomethingAsync();            
 6     EnqueueConditional((() => 
 7         something.IsCompleted || 
 8         something.IsFaulted));            
 9     EnqueueCallback(() =>            
10     {            
11         var another = SomeTestTask.DoSomethingAsync();                
12         EnqueueConditional((() => 
13             another.IsCompleted || 
14             another.IsFaulted));                
15         EnqueueCallback(() =>                
16         {                    
17             EnqueueDelay(100);                    
18             Assert.AreEqual(42, another.Result);                    
19             EnqueueTestComplete();
20         });            
21     });        
22 }

Bennage helped out here as described in his blog post to allow us the following syntax.

 1 [TestMethod]
 2 [Asynchronous]        
 3 public IEnumerable<Task> NewWay()        
 4 {            
 5     var something = SomeTestTask.DoSomethingAsync();
 6     yield return something;            
 7     var another = SomeTestTask.DoSomethingAsync();
 8     yield return another;            
 9     yield return Delay(100);            
10     Assert.AreEqual(42, another.Result);        
11 }

In my opinion this is much better readable. Now microsoft has the new Async CTP library we can however go one step further, by using the the async/await syntax. I’ve made a small modification to the library created by Bennage that allows the syntax below.

1 [TestMethod]
2 [Asynchronous]
3 public async Task AnotherWay()        
4 {
5     await SomeTestTask.DoSomethingAsync();            
6     int result = await SomeTestTask.DoSomethingAsync(); 
7     await Delay(100);            
8     Assert.AreEqual(42, result);        
9 }

The code to do this can be found at github.
