Hi all,
I am currently creating an application in VB.Net under Visual studio 2005. I
am having a doubt the whether these application will run under Visual studio
Dot net 2003 or not. Because i have used the methods which are not available

If you mean

"Can I use VS'2003 to edit/debug this application?"

then the answer is No.
Project files are totally incompatible between VS'2003 and VS'2005
(which is why '2005 offers to take a backup of your files before it
"upgrades" them).

If you mean

"Will my application run with /only/ Framework 1.1?"

then, again, the answer is no.
VS'2005-built applications automatically have a run-time dependency on
Framework 2.0. /If/ you'd only used functionality available in
Framework 1.1 then you /might/ be able to do this (I've never tried but
I /think/ it can be done).

HTH,
