I think that, ideally, the .Kemiksiz Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's hamiş too hard to create a couple of methods that will allow you to sort an IList as you would a List.

A List object allows you to create a list, add things to it, remove it, update it, index into it and etc. List is used whenever you just want a generic list where you specify object type in it and that's it.

The Cast function is just a reimplementation of the extension method that comes with 3.5 written bey a C# IList Nasıl Kullanılır uygun static method. It is quite ugly and verbose unfortunately.

I know that IList is the interface and List is the concrete type but I still don't know when to use each one. What I'm doing now is if I don't need the Sort or FindAll methods I use the interface.
