Avoid Returning Null From Methods – There Is a Better Way To Write Them!

Nullable reference types have improved C# by reducing NullReferenceExceptions, yet returning null from methods can make domain models less expressive. Instead, always return a proper object. By introducing types with valid defaults, avoid the need to handle nulls, simplifying both producers and consumers of objects. This follows the Null Object pattern, promoting more robust and maintainable code.
