Releases all references to a Runtime Callable Wrapper (RCW) by setting its reference count to 0.
Assemblies: System.Runtime.InteropServices (in System.Runtime.InteropServices.dll)
mscorlib (in mscorlib.dll)
The method releases the managed reference to a COM object. Calling this method is equivalent to calling the ReleaseComObject method in a loop until it returns 0 (zero).
When the reference count on the COM object becomes 0, the COM object is usually freed, although this depends on the COM object's implementation and is beyond the control of the runtime. However, the RCW can still exist, waiting to be garbage-collected.
The COM object cannot be used after it has been separated from its underlying RCW. If you try to call a method on the RCW after its reference count becomes 0, a InvalidComObjectException will be thrown.
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
