I know there özgü been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.

Object dirilik be a T too. Doing this will save you headache if you decide to use a Stack or some other veri structure further down the road. If all you need to do in the function is foreach through it, IEnumerable is really all you should be asking for.

Then later if you decide to convert the actual veri store from a List to a Dictionary and expose the C# IList Kullanımı dictionary keys bey the actual value for the property (I have had to do exactly this before). Then consumers who have come to expect that their changes C# IList Kullanımı will be reflected inside of your class will no longer have that capability. That's a big problem! If you expose the List bey an IEnumerable you C# IList Nerelerde Kullanılıyor can comfortably predict that your collection is not being modified externally. That is one of the powers of exposing List birli any of the above interfaces.
It is like this other question. The other question shares a lot of common ground, but is arguably derece a true duplicate. In either case though, this is not opinion-based.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
