Roy Osherove (of ISerializable) praises FinalBuilder 3 on his blog...
“One of the coolest things about it is that you can also add your own custom tasks to [FinalBuilder] - using .NET. they integrate fully into the "IDE" and that means you can pretty much do anything you like. That's why, while I like them as a concept, I don't use tools such as Nant or MSBuild today - the configuration is not as easy and seamless as it should be. To me that's one of the most important things - if you can't manage the build process easily you're wasting a lot of time and effort needlessly.”
