What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?
Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does not contain an array, so all of a sudden, we had almost no use of the large object heap.
If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.
Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.
so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.
class Kisi string ad; string soyad; public string Ad get return ad; grup ad = value; public string Soyad get return soyad; takım soyad = value;

This example also tells you that there C# IList Neden Kullanmalıyız may be situations when you need to specify the implementation, derece the interface, in the argument list: In this example, whenever you require a particular access performance characteristic.

The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it katışıksız to use List.
So typically, C# IList Neden Kullanmalıyız your methods should accept and return interfaces for collections. This leaves your own implementation and your C# IList Nerelerde Kullanılıyor callers room to decide on the actual implementation bey required.
additional advantage is that your code is safe from any changes to concrete class birli C# IList Kullanımı you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there bey long as the concrete class inherits from the interface you are using.
