In C# you use “null” to indicate a lack of value. This is, in a sense, both too permissive and too restrictive. I covered the “too permissive” aspect, the fact that you can’t ask for a reference that’s not potentially null, in a previous post. In this post I’ll be covering the “too restrictive” aspect, and implementing a reasonable solution in the form of an option type.
