I don't believe this is a LabVIEW issue. The same thing happens if your class is called from a C# app. The problem lies in the .NET garbage collection. The destructor for a class can't be called directly. The .NET Garbage Collector will call the destructor(s) "as needed". You can, however, explicitly call the Garbage Collector via System.GC.Collect(). What I don't know is if the LabVIEW<->.NET interface will automatically call the Garbage Collector when the references are all closed out.
