• Is it wrong to use the Dispatcher within my ViewModel? 3 answers
• 在我的ViewModel中使用Dispatcher是错误的吗？ 3个答案

There is a background thread in the viewmodel. It is trying to set a usercontrol property there which is being binded to the view. In simpler terms, accessing a UI thread from a non UI thread. What are the ways to establish this?

viewmodel中有一个后台线程。它正在尝试在那里设置一个绑定到视图的usercontrol属性。简单来说，从非UI线程访问UI线程。有什么办法来建立这个？

Thanks in advance.

提前致谢。
