Hi Mark,

From what I know you should not.

Runtime Callable Wrapper (RCW) manages COM creation. So, COM lifetime is controlled by Common Language Runtime. The COM component is freed from memory when .Net garbage collector calls the Finalize() method in Runtime Callable Wrapper. Internally it calls Release() of IUknown interface of the actual COM object.

To explicitly remove COM object from memory you can invoke the static method on Marshal class in System.Runtime.InteropServices namespace:

using System.Runtime.InteropServices;     
Marshal.ReleaseComObject(myComObjectRCW);
