Why does InvokeRequired return false when you'd like it to return true?

I’ve seen a number of developers surprised by InvokeRequired returning false in situations when they know it’s a cross thread call.

The reason is that the underlying window handle associated with the control has not been created yet at the time of the call.

Since InvokeRequired is meant to be used with either BeginInvoke or just Invoke, and neither of these methods can succeed until a windows message pump gets associated with the control, it elects to return false.

It is kinda weird seeing a page where the content is about developing being close to 1 mb in size.
