I don't totally disagree with the sentiment of over-architecture being a real sıkıntı. However I think that especially in the case of collections that interfaces really shine.

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.
In addition to the older code that doesn't know about generics, there are also a lot of cases where you know you have a list
then, say, if you had an array and wished to print their type names to the console, you would first have to create a new List and fill it with your types.

Ask those people what they'd like the methods to return. Your C# IList Nerelerde Kullanılıyor question is fundamentally "how do I know what software to write?" You know by getting to know C# IList Neden Kullanmalıyız what problems your customer başmaklık to solve, and writing code that solves their problems.
In most cases, if you are using a List and you think C# IList Kullanımı you could use a narrower interface instead - why not IEnumerable? This is often a better fit if you don't need to add items. If you need to add to the collection, use the concrete type, List.

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. Am I right? Is there a better way to decide when to use the interface or the concrete type?
Returning a read-only C# IList Nerelerde Kullanılıyor interface such bey IEnumerable is often the way to go for data-retrieval methods. Your consumer sevimli project it into a richer type as-needed.

It doesn't affect C# IList Nasıl Kullanılır the signature of the method, and is kaş in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is where his confusion clearly lies.
