Try
  Dim first as Integer
and
  Dim second as Integer

and check the IL code again.

In VB.Net, if you do not specify the type, you get the default Object type, which needs to be boxed. Recall in the earlier incarnations of VB, you have Variant.. In some sense, it is analogous.

and you should see the boxing is gone.

Ah..... the joys of late type-binding. I remember having an "easy" programming experience the first time I started my development career with VB, then having a short tough period of cold turkey getting into the habit of explicit type casting when switching to C#.
