LoaderLock occurs on shutdown when using DockingManager and Oracle provider

Question

If I use just the Docking Manager or just Oracle, I don''t get any shut down errors, but If I use both of them in the same app, I get multiple errors on shutdown.

Anyone else seeing this behavior?

You might post this on the Tools forum so DockingManager engineers can see it.

This had been fixed for me in an earlier DirectTrac incident, I had just forgotten.

The gist is that if you want to use a Docking manager you need to supply an IComponent to the constructor.  By default, dragging a docking manager onto a form will use the Default constructor (which doesn''t get this parameter).

I created a user control based on the DockingManager and in this control I only provided a constructor that takes the IComponent.  This fixed both the shutdown error and allows me to drag/drop docking controls onto forms.
