Considering SQL support for classes.

Entity Framework has some issues trying to process the Dto's as models. I'm considering adding support via adding [key] attributes to the dto's however this would add Entity Framework as a dependency so would this be acceptable for the master branch?

After looking into this, it seems I could run into plenty of issues including the use of Dictionaries and Lists throughout the Dto's. If anyone else has any ideas they'd be appreciated.

This concerns me, adding dependency of EF into the project would not be good. Riot services also responses Map[string, object] in many api calls, this is translated as Dictionaries in C# and indeed it would have a problem with EF. A possible solution would be to create EF models that derives from each DTO and adding an Id key as a new property for each model. I will investigate further, thank you for mentioning it.

Check out this implementation for getting entities from Riot service and then storing them at RavenDB NoSql Database for later use and caching.
