To make the keyboard ShiftLocked upon first load (so that the first character is uppercase and all subsequent characters are lowercase) I call these lines in _Loaded event:

virtualKeyboard.SendKey(MindFusion.UI.Wpf.Key.Shift);
virtualKeyboard.ForceUpdateLayout(); 

When using the virtual keyboard via touch, this works great. VKB is all uppercase, I tap a letter and it's displayed correctly AND the virtual keyboard switches to all lowercase.

But when using an external keyboard, it never leaves the ShiftLocked state after the first character is entered on the keyboard. If I type the number keys on the keyboard, they come out like (!, @, #, $) as if I was holding shift down the entire time.

Any ideas?

Yes.  I upgraded from a very old FPS.VirtualKeyboard control to the latest MindFusion control which I recently purchased.  The FPS version was 3.2.3.0.

That being said, I had to refactor a lot of code to integrate the MindFusion VKB,  so it's possible I broke something.  I just don't see how to make this work like it used to.
