For example, int, Guid, string, IPAddress. These are (somewhat loosely) called "primitive types". Objects that are structured to hold multiple values, and where the identity of the object is defined by a key value. For example, Blog, Post, Customer. These are called "entity types". Objects that are structured to hold multiple values, but the object has no key defining identity. For example, Address, Coordinate. Raw SQL queries can now be composed using LINQ operators.
