no and no. the work fine side by side. to compile to 2.0 you will
have to upgrade your code to VB2005.

....which means of course that you won't be able to open it in VB2003 any
more, so make a backup before you open your projects in VB2005.

No. If you have VS.NET 2003 installed, you must not uninstall .NET 1.1
because VS.NET 2003 is tied to .NET 1.1. VS.NET 2003 cannot be used to
develop .NET 2.0 applications.

You cannot open the solutions in VS.NET 2003 after upgrading them to VS 2005
any more.

Does this mean that if I develop a vb.net 2003 application it will not run on
computers that have only the 2.0 framework installed?

Also, if I only have 2.0 framework installed, can I still develop
applications using VB.Net 2003 (of course the newer 2.0 framework classes
won't be available)?

IIRC .NET 1.* applications should run on .NET 2.0.

VB.NET 2003 depends on .NET Framework 1.1. So .NET Framework 1.1 must be
installed. You can still develop .NET 1.1 assemblies although .NET
Framework 2.0 is installed.

Thanks. I'm surprised that you can't install and run Vs 2003 IDE with just
the 2.0 framework installed.
