I've heard a lot about the amazing-ness of type providers, but no-one seems to know how they work aside from saying something betwen they generate types for you, and they generate intellisense for you.
I'm sure it all makes sense once you go ahead and play with it, but it looks like I'll have to be watching some videos to grok what is really going on.
I think its knowing what's reasonable to expect from them and what's not reasonable i.e. what is static, what is dynamic, if there are artifacts how do they get created, what if the data schema is dirty...
some of these questions I can answer myself just playing around with them, but I think I'd have to be comfortable implementing them before being comfortable using them.
