Is there a technical limitation to the number of Properties that one Content Type can have? if not an absolute limit, would there be an approximate point where performance would degrade if there were, for example, hundreds of Properties?
Have never stumble upon this questions before. I should ask my self why should I have 100 properties on one type? Would it be a great expericens for editors with hundreds of properties on one type? Probably not. If you need to have a type to story properties I might sugest looking into other solutions for you models like EF for instance.
Regarding you questions though I have not exprienced any performance trouble but then again I have not had any types with hundreds but almost 100 properties though. But maybe someone from episerver can tell if there is a limit?
