Hi all I am succssfully developing an active website on Vista using VS2008 and ASP 3.5 . It runs beautifully in www.root Currently I have access to a remote asp website running on Windows Server 2003 with .Net Framework 2.0. Not much joy when I copy in a 'built' version of the website and I suspect I need to to understand the followng issues in the VS2008 prospectus quoted below "Visual Studio 2008 also provides developers with the ability to target multiple versions of the .NET Framework from within the same development environment. Developers will be able to build applications that target the .NET Framework 2.0, 3.0 or 3.5, meaning that they can support a wide variety of projects in the same environment.. Where can I find the meterial which will enable me to understand the limitations and implementation of this facility. It doesn't seem to crop up in the Wrox ASP .Net 3.5 Manual which I am using as my bible Roger Stenson
