For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

The total number of interface IDs contained in the interfaces specified by template parameters I0 through I9.

static const unsigned long IidCount = Details::InterfaceTraits<I0>::IidCount + Details::InterfaceTraits<I1>::IidCount + Details::InterfaceTraits<I2>::IidCount + Details::InterfaceTraits<I3>::IidCount + Details::InterfaceTraits<I4>::IidCount + Details::InterfaceTraits<I5>::IidCount + Details::InterfaceTraits<I6>::IidCount + Details::InterfaceTraits<I7>::IidCount + Details::InterfaceTraits<I8>::IidCount + Details::InterfaceTraits<I9>::IidCount;  

The total number of interface IDs.
