Does Spark use the Entity Framework?

Does spark use Entity Framework?

No, Spark does not use Entity Framework, but rather it is an alternative to the Entity Framework.
Spark provides a MicroORM which is based on the Active Record pattern. It provides very fast, light-weight, and flexible data access.
If your apps need to run fast, particularly under heavy loads, then Spark will handle this for you. 

Hope this helps.
