VS Studio 2005 versus 2008 & .NET 2/3

Hi!

We're developing websites with VS 2005 (.NET 2.0) and we want to move on to
.NET 3.X (Not the whole team but the R&D team).

Do we absolutely need to upgrade to Visual Studio 2008 to do that? Is that
the same thing going from 1.X to 2.0?

Will we be able to open .NET 2.0 projects from VS 2008 without conversions
and still be able to open the same projets with VS 2005?

Thank you very much

No, it's a much smaller step than 1.X to 2.0. The conversion from 1.1
to 2.0 involved a completely new project file format, rather than just
a version number change. Also, you couldn't target 1.1 (easily) from
VS2005, so changing IDE automatically changed the target framework.

You won't be able to open VS2005 projects in VS2008 or vice versa, but
you can target .NET 2.0 from VS2008, and you can maintain parallel
project files if you absolutely have to.

No, you do not have to upgrade, but you will have to edit with notepad and
use the command line compiler. :-)

Actually this is less painful than 1.x to 2.0, as you can compile to 2.0 in
VS 2008. You can also leave VS 2005 installed on the machine.

No, but as the major upgrade change is the solution file, you can aim two
solution files at the same project. This works okay for web projects. I have
not really tried with windows projects.
