XAF 如何用其他线程更新对象

// Developer Express Code Central Example:
// How to update a View object from another thread.
// 
// It is well known that most Windows Forms are not thread safe, and all changes to
// these controls should run (be marshaled on to) the thread processing windows
// events (the main UI thread). Worker threads are often used to do lengthy
// calculations or process asynchronously messaged events, allowing the UI to react
// to the user while these tasks are operating. This example shows how bypass this
// limitation by updating the object directly in the database, and then refreshing
// the view to reload the current object. This is a little bit tricky, but works
// quite well. Another known workaround, is marshaling actual work to the main UI
// thread, for instance in the main form. You can learn more about this in MSDN,
// Google, etc. For instance, here is a good article:
// http://weblogs.asp.net/justin_rogers/pages/126345.aspx
// 
// You can find sample updates and versions for different programming languages here:
