The server caches the exception for you and if you call the end operation completion method for your async call it will throw any exceptions that occured.

private void go_Click(object sender, EventArgs e)
{
    client.BeginDoMyStuff(myValue, new AsyncCallback(OnEndDoMyStuff), null);
}

public void OnEndDoMyStuff(IAsyncResult asyncResult)
{
    this.Invoke(new MethodInvoker(delegate() { 
        // This will throw if we have had an error
        client.EndDoMyStuff(asyncResult);
    }));
}
