        The .NET framework applications can be run on computers that have newer .NET frameworks than what the application was compiled on, but .NET applications are not downgradable. .NET 2.0 applications will not work with .NET 1.1 systems. Visual Studio 2003 can target .NET 1.0 and .NET 1.1 applications, and I believe Visual Studio 'Orcas' will be able to target .NET frameworks 3.5, 3.0,2.0,1.1,1.0 but I could be mistaken.

        Regards, Thomas Stockwell Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning. Visit my homepage Oracle Studios[^]

          It all depends on what you're doing and what methods/namespaces you are using. Sometimes an app written in .NET 2.0 will run on 1.1, and sometimes it won't. When you're using the VS Help file or MSDN, it will say what's compatible with what version of .NET.

            Backward compatibility would be if 2.0 could run a 1.1 application, which it can. How on earth could the 1.1 Framework predict what it's going to need to run the more advanced features of the 2.0 Framework?? I can't!

              :confused: 1.1 apps would run on 2.0. However, please take a note of these breaking changes. http://msdn2.microsoft.com/en-us/netframework/aa570326.aspx[^]
