C# - Add Discriminated Unions and a Maybe / Optional type and F# style records. C# - I'd remove null propogation, I'm sick of seeing code like this now foo?.Bar?.FirstOrDefault(x => x?.Quax?.Something == y?.Something).DoStuff(); We have someone here now who just makes all null reference exceptions go away by appending a ? to every call!!! Drives me nuts.
