Can I easily upgrade my VS2003 projects to VS2005?

I appreciate that VS2005 uses dotnet framework 2.0 whereas VS2003 uses dotnet framework 1.1 but is there a tool to upgrade/convert my old VB.Net apps written in VS 2003 to VS 2005?

    you can open the VS2003 project/solution using VS 2005, and that should do the conversion for you.  There may be a few minor manual fixes that you might need to make, but otherwise the upgrade should be fairly painless.

    Try it, and see for yourself.

    I'm just agreeing with what Arthur said. I have heard that ASP.NET apps are sometimes more troublesome, but I have converted Winforms apps and was able to simultaneously build in both 2003 and 2005 by keeping to the old features and keeping the project and solution files separated - those appear to be the only files that are not compatible between the two versions of VS.

    The answer for where to go for a new copy and what it'll cost you depends substantially on 1) where you live, 2) whether or not you're a student, and 3) which edition of VS you want.

    Froogle ( can give you lots of options, but if you're not in the U.S., you may have difficulty sorting through what's there to find who will ship to you. Personally, I (in the U.S.) most often get software at (which also often has older versions of software, useful when you don't need or want the latest and most expensive).

    The academic version is a fraction of the price for non-students. I picked up the academic version of VS 2003 when I took a VB class at a community college, and found that the discount on VS virtually paid for the cost of the class.

    The Standard edition is much cheaper than the Professional edition (and both of them will cut $100 or so off the price if you get an Upgrade version, which you qualify for if you have a legit copy of VB 2003). For the differences in what you get between the different editions, see
