There are many report engines out there for .NET like Crystal, List & Labels, etc.
What report engine are SF users working with?
At this point I need to start looking a reporting tool and want to use something that can work well with SF and if possible re-use the BO classes in my SF project.
Thanks!
Every user will likely give you their own opinion on why the use the engine they're using; and all of the engines have features that make them worthwhile, so don't just jump on one until you look at at least a couple of them.
