VB.Net & C# WIndows application exe size

[Ily]

Hi

I have created a simple application in both vb.net and c#

Both apps display a hello in a messagebox in the form load event

When compiled:

the vb exe is 10KB
the C# exe is 20KB

Why the difference?

Illy,

You can see the differences yourself.

ildasm VBApp.exe /out=VBApp.il
ildasm CSharpApp.exe /out=CSharpApp.il

This will disassemble your executables into intermediate language code.
Use any textual comparison tool to see the difference.

Are you sure both are debug/release builds?

If you're using 2005, then the difference is likely due to the hidden files
VB uses to support part of the My namespace functionality (look in the
project directory to see what I mean). You'll see that there are more files
for the VB project: e.g., Application.Designer.vb and ApplicationEvents.vb.
This will be enough to cause the difference in exe size you're seeing.

With a non-trivial application, the difference will be nominal (i.e., about
10k).

Mhm... Accoding to the OP the C# executable is larger than the executable
created with VB:

D'oh!!
I was so sure of the answer, I didn't pay enough attention to the question!
