    Great tutorial! Nice advanced (and correct) structure made simple. With so many bad approaches to API tuturials out there, this is the one to follow! Keep the great work and thanks for sharing it...

    8:45 you say an ICollection is only read only - I believe you are referring to IEnumerable, ICollection you can add / remove but only to the end. IList has index so edit anyplace.

    Hi Teddy. With IEnumerable and ICollection, can you use either or is it convention to use one and stick with it? Cheers

    Use IEnumerable when you need to filter data. ICollection has more features like .length and CRUD actions.

    I’ve always found that going the extra and creating your own mappers can save time because you never have to debug them and can always easily change to meet needs

    Hey Teddy, thank you so much for this Tutorial. As an Software Developer that is familiar with the basic concepts of things like DI etc. it is easy to follow. I could imagine, that it could be hard to follow, if you dont have that background knowledge. Maybe you could link Videos that go a little deeper in that concepts in the sections. :) Greets Tilman
