Answer / sivasubramanian.k

A Runtime Callable Wrapper (RCW) is a proxy object
generated by the .NET Common Language Runtime (CLR) in
order to allow a Component Object Model (COM) object to be
accessed from managed code. Although the RCW appears to be
an ordinary object to .NET clients, its primary function is
to marshal calls between a .NET client and a COM object.

For example, a managed application written in C# might make
use of an existing COM library written in C++ or Visual
Basic 6, via RCWs.

The runtime creates exactly one RCW for each COM object,
regardless of the number of references that exist on that
object. The runtime maintains a single RCW per process for
each object. If you create an RCW in one application domain
or apartment, and then pass a reference to another
application domain or apartment, a proxy to the first
object will be used.
