VB.NET, nullables and the ternary operator:
Dim i As Integer? = If(True, Nothing, 5)
This took me some time to debug, since I expected i to contain Nothing.
What does i really contain? 0.
This is surprising but actually "correct" behavior: Nothing in VB.NET is not exactly the same as null in CLR: Nothing can either mean null or default(T) for a value type T, depending on the context. In the above case, If infers Integer as the common type of Nothing and 5, so, in this case, Nothing means 0.
