Can C# dll's be integrated with a LabWindows project?

Question

Hi,
I've integrated C++ dlls into LabWindows projects before, but recently I've been given a C# project that I would like to use instead of deconstructing the source and reconstructing it in C++.
Is there any way of doing this and if so what are the differences between C++ and C# integration? Or am I looking at a minimum of a C++ wrapper?

Okay, have made progress but I have a question regarding object destruction.
When I create a link to the C# dll I get a .fp, .c, and .h file which I naturally build into my project
At the top of the .h file are listed the following:
// Global Functions
int CVIFUNC Initialize_TB_USB_Comms(void);
int CVIFUNC Close_TB_USB_Comms(void);
// Type: DipoleRxUSB.USBInterfaceExternal
int CVIFUNC DipoleRxUSB_USBInterfaceExternal__Create(
 DipoleRxUSB_USBInterfaceExternal * __instance,
 CDotNetHandle * __exception);
I note that there is no Destructor type call to compliment the Create
In the required functionality I call the Initialise_TB_USB routine, then the Create routine - followed by all the other stuff I need to do, and finally the Close routine.
However I know from experiment that this doesnt destroy the object created by the Create routine, as if I come in again I can still access the previously created objects functions.
So how do I go about destroying the instance of the dll I assume I've created. I have put a default constructor and destructor in the C#, but this doesnt seem to have had any effect.
What am I missing?
