Do I have this right...

When I hit the Build command, the program is compiled into Intermediate language.

When I come out of the IDE and run my new program for the first time it is compiled from the IL into Native code.

I can understand the first part, that seems fair enough. But if I examine the EXE's size before and after the native compilation, the size has not changed.

It seems to me that native code would take up less space than IL.

Whats the deal?
