I need some kind of abstract class as WinRT component. I want to make several WinRT components, which will contain the same functions (with different implementations). I would use abstract class and subclasses, but this construct seems to be forbidden for
WinRT (why?). So I am trying to use interfaces, but this does not work too, compiler always throws internal error while importing the second component from assembly.
It also throws warning C4945 (symbol has already been imported from another assembly - related to the interface).
Any idea how to solve this? Thanks.
