/***************************************************************************************************************
 
        BE CAREFUL WHEN MODIFYING THIS FILE. ORDER OF METHODS SHOULD MATCH EXACTLY TO V-TABLE LAYOUT !!!!!
 
        Note that DispId attribute is skipped since we are the only client and DISPIDs are never
        used when .Net component invokes dual interface methods on a COM object since CLR always calls
        through the v-table. TypeLibTypeAttribute is ommitted as well, once again since we are the only client
        All base interface methods must be duplicated on the definition of the derived interface.
        Methods that will not be used (at least at this time) can be replcased with the void Placeholder()
        If method returning the interface that will not be used, in order to prevent the baloon  effect
        simply return object.
 
        [PreserveSig] Can be used when needed in order to get back HRESULT. If not used && FAILED(hr)
                      Exception will be thrown
