Where can i find the ThreadPool.SwitchTo method?

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

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