Lightspeed Express and Standard

Hi there, Sorry for what might be an obvious answer but what does it mean when the Express and Standard versions have an 8 model class limit and a 30 model class limit respectively? Does this mean that using the standard version, only 30 classes mapped to 30 tables in the backend DB can be generated? Does a runtime exception occur when 30 is exceeded or a compile time error? Or are the Lightspeed Model classes the items you add to a project but can contain any number of table mapping classes? Thanks.

The limit refers to how many classes can be mapped to the backend database, and is enforced by a runtime exception.  For example, if you are using Express edition, when LightSpeed encounters the 9th class that needs to be mapped to a table, it will throw an exception.  Similarly if you are using Standard edition and LightSpeed encounters the 31st class.

Therefore, you can add any number of entity classes to a project, but you can only *use* as many of them as the edition supports.

I'm not sure I've quite understood your final question, but the limit refers to *classes*, not to files or models.  Thus, if you have a .cs file which defines 9 entity classes, or a graphical model that defines 9 entities, that would cause an exception in Express edition (again, at runtime, not compile time).  Does that answer your question?  If not please do follow up.

Yes, thank you. My final question was in regards to my misunderstanding between model class and .lsmodels that you can add to a project. I was unsure if the limitation was on the number of .lsmodels you could add to project but you've answered it in the first part.
