Hi,@兰树豪 . Welcome Microsoft Q&A.

As Viorel said, you could refer to more information here.

You can also read the statement here.

If you weren't supposed to use the method at all, it wouldn't be public: the intent of that attribute is only to hide the member from mechanisms such as Intellisense and other editor-browsers. You don't typically need to use Dispatcher.CheckAccess() yourself, which is probably why it's marked as non-browsable, but the wisdom of this is something we can only guess at (unless Eric Lippert is watching ;-) In summary: just call Dispatcher. Invoke and don't worry about CheckAccess.
