Maybe.Sharp

A generic 'option' type for .Net, explicitly representing a value that is either 'something' or 'nothing'.

    PM> Install-Package Maybe.Sharp

Why ?

Yes there are plenty of maybe/option types for .Net, but I couldn't find one that met all my requirements, hence Maybe.Sharp exists.

Features
