Faking synchronous calls in Silverlight WP7

Question

I\'m porting some code from the full .NET framework to the WP7 version and I\'m running into an issue with synchronous vs async calls.

First I suggest trying to get comfortable with async but if you really want/need to convert an asynchronous call to a synchronous you can use ManualResetEvent to achieve the desired result.

Here is a quick example if usage:

public ManualResetEvent _event = new ManualResetEvent(false);

...
{
    ...
    var wc = new WebClient();
    wc.OpenReadCompleted += new OpenReadCompletedEventHandler(ReadCompleted);
    wc.OpenReadAsync(uri);

    // block until async call is complete
    _event.WaitOne();
}

private static void ReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    ...
    // set event to unblock caller
    _event.Set();
}

Now you code will block on the line _event.WaitOne(); until _event.Set(); is called.

Good Luck!
