I'm just starting with playing with indicator development, I still know just about jack, or thereabouts. So, all I've done so far with CodeSite is prove it works, stuck a "initialize" log message in the initialize event and that kind of stuff. Happy to know that a trusty tool will be available.
SmartInspect is a similar product, though, I've not used it. I presume it would also work with Ninja.
Just thought I'd mention it, for anybody maybe interested.
