FLIR SDK 6 .NET Controller System_Collections_Generics

I am working with a FLIR T530 Camera with USB.  From LabWindows/CVI, I created a .NET Controller to the FLIR ATLAS SDK 6 libraries.  Everything appears working except when calling the function that will discover the USB devices associated with the system.  The Flir_Atlas_Live_Discovery_Discovery_Start_2(handle, time, list, error) has 4 arguments, in which "list" is of type System_Collections_Generic_List_T1.  The "list" returns an address, but there is none of the expected data at that address associated with the USB data structure for each item of the C# List<T>.  So the question is, how is the System_Collections_Generic type handle within the LabWindows?  It is unclear how the allocation of memory is done for generic list type in the LabWindows.  

Here is a simple example of the code.   

From the FLIR.h:

typedef struct __System_Collections_Generic_List_T1 * System_Collections_Generic_List_T1;

From the FLIR.c

System_Collections_Generic_List_T1 list = NULL;
CDotNetHandle hError = NULL; 
Flir_Atlas_Live_Discovery_Discovery InstanceHandle;
Initialize_Flir_Atlas_Live();
Flir_Atlas_Live_Discovery_Discovery__Create(&InstanceHandle, &hError);
Flir_Atlas_Live_Discovery_Discovery_Start_2(InstanceHandle, 10, &list, &hError);
return (0);
