I would like to know if I use C# instead of Vb.Net for Server components,
will there a performance improvement ?

TIA,

Gary
 
No, it won't. What kind of performance issues are you running into?

Hi Gary,
C# and VB.NET should have identical performance (they're both compiled
to IL)

However, VB.NET has virtual methods by default afaik, C# does not.
Virtual methods are little bit slower.

Frans,
Huh?

VB.NET methods are virtual only if one uses the Overridable or MustOverride
keywords.

Overridable & MustOverride are not the default, hence the methods are not
virtual by default!

Hope this helps

I am a long time VB developer so I'm not one to bash it unnecessarily.
However, I have had the fairly unique experience of decompiling an entire
VB.Net app into C#. VB uses a number of techniques to accomplish various
tasks that i'm sure C# handles natively. I would have a hard time believing
that it doesn't lose some efficiency. Probably only on the order of a couple
percent though.

Are you sure about this? Afaik, VB.NET makes methods virtual by
default, but my knowledge about this may be lacking, I'm not a native VB.NET
developer :) I am aware of the Overridable keyword, and am not sure where
I've read that vb.net methods are virtual. So I can be wrong, that's why I
said 'afaik' :)

Not that I'm a VB.NET developer either, but the MSDN says:

<quote>
Properties and methods are NotOverridable by default.
</quote>

(where NotOverridable means the obvious thing).
 
Frans,
I normally use VB.NET, I am positive about this.

Also Jon confirmed it with a passage from MSDN.

Hope this helps

That's clear enough I think:) I was wrong :)
