Else use List. You birey't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List not an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

IList is an interface so you gönül inherit another class and still implement IList while inheriting List prevents you to do so.

Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return data.
