Good question. I answer you. The COM is a sort of interface introduced by Microsoft in 1993 that enables microsoft solutions understand and handle external components other than brought with in microsoft integrated developement environment I mean the local or the native libraries. For example when you install the driver or the software of your new mobile phone into your computer some libraries are added to your operating system enables you to manage your new mobile phone through the code those are managed throught Visual studio via COM interface. You ask me how??What happens inside the kitchen?? I answer you the .Net managed code interact with external code using the RCW Runtime Callable Wrapper. This object is created when a .Net Client load a COM component each COM component has his unique RCW that reads every type method ... of the first one even the parameters and error conversion between the COM and the .Net client is covered by the RCW.
