I’ve read all recommended articles on SynchronizationContext, but there is one small question I did not find an answer for.
In my case I have an event handler that calls a Log() method that outputs text to a TextBox. Log() is called from a WCF service. The event is raised from WCF client instances (threads).
Usually, I check Control.InvokeRequired to be sure I am on the correct thread.

In other words, can I always do a .Post() or .Send() even if I’m already on the correct thread?
