C# Nullable gotcha

Recently I ran into a interesting gotcha will System.Nullable<T>.

Below is some code that was run through the immediate window.

new Nullable<bool>() is bool
false
new Nullable<bool>(false) is bool
true
new Nullable<bool>(false) is Nullable<bool>
true
new Nullable<bool>() is Nullable<bool>
false
