Why Lists are not lowered to a while loop
Read OriginalThis technical article analyzes C# compilation, explaining why the 'foreach' loop over a List<T> is not lowered to a simple array-indexing while loop like it is for arrays. It details the versioning safeguard that prevents collection modification during enumeration and discusses why similar optimizations aren't applied to IReadOnlyList<T> due to complexity and lack of O(1) indexer guarantees.
