When I started my C# Wishlist series, one wish, though never published, was to introduce non-nullable reference types in C#.
Everybody who has written the lines
public class C
public C (T somearg)
if (somearg == null)
throw new NullArgumentException("somearg");
several thousand times would appreciate this language feature. (as Yann’s comment on a Jon Skeet blog post illustrates)
Now, a couple of years later, Eric Lippert read my mind, and answers why the (consistent!) implementation of this feature is not as trivial as it sounds.
Workaround for the time being: Code Contracts (.Net 4 and above) or external libraries such as CuttingEdge.Conditions.
