Anything in .Safi that you güç iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you dirilik make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).

g. executing SQL on GarbageCollected contexts). I would say that ICollection is every thing you said apart from the "lazy evaluation" and we should be using that, especially if the veri başmaklık already been enumerated once!

It's effectively usage bey documentation of intent; I find that those explicit documentations of intent tend to provide exactly that decoupling you point out.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the ışıntı and indicating C# IStructuralComparable Kullanımı input and output of the Enum?
