I have built my web site with Visual Studio .Net 2002 and .Net Framework 1.0. Can I expect problems when upgrading to Windows Server 2003 as Web Server?
Windows Server 2003 comes with .Net Framework 1.1, build 4322 pre-installed.
This is the same version that comes with Visual Studio .Net 2003. It is possible
that some of your code will fail on .Net Framework 1.1, as it is more secure,
and you might have to change things to get your code to work. It is also
possible to run .Net Framework 1.0 side-by-side with 1.1, until you have fixed
your code to be 1.1 compatible. Here are some interesting links:

Compatibility Considerations and Version Changes
If you are unsure if your web application will run on Windows Server 2003, download or order the Evaluation Edition from Microsoft and
try it before upgrading.
