I don't get this. If I write List<animal> animals = cats then that should mean that I am open to adding any animal type to the list, even though I initialized it with felines only.

What is the problem in having a list with mixed animal types? Unless there is some technical limitation that prevents it, it seems just an unfortunate limitation.

For building a website you should start by learning HTML.

I made the following test: I built several GeometryModel3D objects with the same material. Then I changed the material for one of them and that changed the material for all the other objects that share the same material. Next I built GeometryModel3D objects each with its own material. I changed the material for one object, but the others were not affected. Conclusion: if I use one material instance for each GeometryModel3D instance, that will occupy more memory.

No, because I don't know how to detect the difference. I'd like a theoretical answer and not only a practical one. Does creating more brush instances occupy more memory than assigning a single brush to many GeometryModel3D objects?

Thanks. This comment answers my question.

NotPolicallyCorrect's comment answers my question completely. I am not interested in explanations about how the interface works. I only want to know the reason for why we use it.

Thanks Garth. Your example could not 'undo the good work' because this is a very simple example and I have already been working with more complex examples as I am creating a WPF app. I understand completely what an interface is and how it works, but I am only trying to understand the reason for why we use them.

Thanks. What you say makes sense to me.
