Question

I am studying the new Async CTP and going through some sample code,

I came across this piece of code:

public async void button1_Click(object sender, EventArgs e) 
{ 
string text = txtInput.Text; 

await ThreadPool.SwitchTo(); // jump to the ThreadPool 

string result = ComputeOutput(text); 
string finalResult = ProcessOutput(result); 

await txtOutput.Dispatcher.SwitchTo(); // jump to the TextBox’s thread 

txtOutput.Text = finalResult; 
}

Please where do I find ThreadPool.SwitchTo? SwithcTo method is not on the ThreadPool class

i have a referece to AsyncCtpLibrary.dll … but no luck

For reference, CharlesO answered his question within the comments above:

OK, found it guys, Summary: Provides
methods for interacting with the
ThreadPool. Remarks: ThreadPoolEx is a
placeholder.

Public Shared Function SwitchTo() As
System.Runtime.CompilerServices.YieldAwaitable
Member of
System.Threading.ThreadPoolEx Summary:
Creates an awaitable that
asynchronously yields to the
ThreadPool when awaited.
