e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you dirilik achieve decoupling but not achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.

By adding on a Where statement you aren't actually doing much of anything, you're just adding an extra filter to the query so that later on, when you actually evaluate the sequence (in this case, when ToList is called) those filters will all be applied.

Önceki C#’ta IEnumerable ve IEnumerator Interfaceleri Nedir? ve Nasıl Kullanılır? mebdelıklı makalemde IEnumerable ve IEnumerator interfaceleri üzerine uzun uzun konuşmuştuk. Bu yürekğimizde ise müntesip interfacelerin asenkron enfrastrüktürda şekillendirildiği C# 8.0 ile gelen yeni hallerini(IAsyncEnumerable ve IAsyncEnumerator) süjeşacağız. Şimdi fevkda adresini C# IEnumerable Kullanımı verdiğim makalemizide referans alarak mevzuyu en temelden geçekırlayarak ele alalım.
