VS 2003 & VS 2005 together
 

Is it or will it be possible to target VS.2003 projects from one build project and VS 2005 from a separate build project on the same machine?

The scenario is that we will branch our code when we move to VS 2005. We will continue to build existing code for framework 1.1 and VS 2003 but will also need a second build to target the new code base for framework 2.0 & VS 2005 on the same machine.

Will this be possible with Visual Build?

Thanks,
Jim

Yes, that is currently supported. The Make VS.NET action determines the appropriate version of VS.NET to invoke based on the project/solution file version. See the Make VS.NET action help topic for full details.
