One of the new features of Visual Studio 2008 is the ability to target multiple versions of the .Net framework with your application. I briefly mentioned this my last editorial, but I thought I’d expand on it here and help you understand why this is a very good thing for developers.
One of the problems many people faced with Visual Studio 2005 was that it only allowed you to develop .Net 2.0 applications. The benefits of moving to .Net 2.0 from 1.1 are pretty obvious (check out the guided tour for details), but the issue people had was that they still had to develop and support their old applications which meant that the new IDE would have to wait until they either upgraded or they started a new project.
This will also mean that if you want to upgrade your p roject from .Net 2.0 to .Net 3.0 or 3.5 you can do this simply by changing the target framework version in the project properties. This doesn’t mean that there wont be upgrade issues to think about, but at least you don’t have to change tools and upgrade your projects to see what happens when you upgrade to the latest framework – which should make the upgrade process significantly easier.
Unfortunately if you are on .Net 1.1 or 1.0 you’ll still need to move to .Net 2.0 (which you could do on Visual Studio 2005 today) before you can take advantage of Visual Studio 2008, but we are working hard to make it easier for you to get the latest tools and move your applications through the upgrade process.
