Pragmatic editor Susannah Pfalzer interviews authors Jeff Cohen and Brian Eng, asking "what do .NET developers find so compelling about Rails?" Jeff and Brian go on to explain the key differences between the .NET environment and the open source environment of traditional Ruby and Rails, the importance (and adoption) of MVC, unit tests, and differences in development styles. They'll also explain how to use the right tool for the job and take a quick look at IronRuby, and Ruby's interoperability with .NET.
