Read Original

This technical article examines the concept of mutable value types (structs) in C# and .NET. It explains why they are generally considered problematic due to copy semantics, using examples with DateTime and custom structs. The article also discusses why the .NET framework uses them in specific scenarios, such as in List<T>.Enumerator, primarily for performance optimization.
