Well, Depends on which type you are referring to (Which is part of what pains me with nullable ref types, as nice as it is to have) If it's a value type (T), ?

Well, Depends on which type you are referring to (Which is part of what pains me with nullable ref types, as nice as it is to have) If it's a value type (T), ? will make it Nullable<T> and provide the behavior described. Reference types however can always be null, and do not have a .HasValue as exampled above. However newer versions of C# let you declare nullable references on a compiler level, but rather than HasValue/Value you still have to do the null check and instead can bypass via the new deref operator (!)
