备注:WindowsFormsSynchronizationContext是Winform程序中用得很多的SynchronizationContext，在我们的SCF代码里则使用了另一个子类DispatcherSynchronizationContext.

这也是WPF程序默认的

private void Button_Click(object sender, RoutedEventArgs e)
?????? {
?????????? var context = SynchronizationContext.Current;
?????????? Debug.Assert(context is DispatcherSynchronizationContext);
?????? }
