I have C# Windows Forms application which works with C++/CLI Library. Library class works with camera and has clean-up function ShutDown. Wnen C# client exits, it calls ShutDown function and all works OK:

Camera camera;          // form class member

Form_Load:
    camera = new Camera();

Form_Closing:
    camera.ShutDown();

But when program has unhandled exception, camera.ShutDown function is not called. Result of this is that process remains active and must be killed from Task Manager. How can I call this function in any case?

Camera class has destructor which calls ShutDown, but this destructor is not called in the case of exception.

I think you have to handle yourexceptions with try catch finally block.  In the case of unhandled exception i don't think anything gets called

I don't want to handle all exceptions, I handle only exceptions which I expect to happen. Bugs in the program must remain unhandled. My problem is that class instance is not destroyed after unhandled exception.

Does the app actually crash when you have an unhandled exception? or does it continue

It looks exactly like my case. The bad news are that there is nothing to do with this.
