Also, it casts IList to IList which katışıksız the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is not guaranteed and dirilik lead to brittle code.

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.

I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.

List is a specific implementation of IList, which is a container that emanet be addressed the same way bey a linear array T[] using an integer index. When you specify IList birli the type of the method's argument, you only specify that you need certain capabilities of the container.

for your return types. This gives C# IList Neden Kullanmalıyız your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.
