Title
Body
In F# mantra there seems to be a visceral avoidance of null , Nullable<T> and its ilk. In exchange, we are supposed to instead use option types. To be honest, I don't really see the difference. My understanding of the F# option type is that it allows you to specify a type which can contain any of its normal values, or None . For example, an Option<int> allows all of the values that an int can have, in addition to None . My understanding of the C# nullable types is that it allows you to specify a type which can contain any of its normal values, or null . For example, a Nullable<int> a.k.a int? allows all of the values that an int can have, in addition to null . What's the difference? Do some vocabulary replacement with Nullable and Option , null and None , and you basically have the same thing. What's all the fuss over null about?
