VS2013, Win7 (32-bit)

I'm writing a WPF app that utilizes MEF, and one of the modules (the one I'm testing) uses interop services. When I run the app to test the module, the app shuts down with no indication that anything is wrong. I've put try/catch blocks around the code where it stops, and no exceptions are being thrown.

In the IDE's output window, I get the following error:

The program '[37424] BODModules.vshost.exe' has exited with code -1073740791 (0xc0000409).

I've tried turning on debugging of unmanaged code, to no avail.

I have no idea why this is happening.

Anything in the event log?

.. which (googling) suggests it might be strings aren't being handled correctly. BSTR type stuff.

I suppose that kinda makes sense...
I took out the code I thought might be the culprit, and no change...

Any 3rd party library being used? Could be blowing up in a call to that where .NET isn't going to see an exception.

Not in this case, no.
