Object Service Layer in Entity Framework keeps track of the changes made to the object and updates the database accordingly. In this chapter, we discussed Object Services and saw how it can be used to perform CRUD operations against the EDM. We discussed how we can serialize and deserialize an entity instance. We implemented a sample application that demonstrated how we can detect and resolve concurrency conflicts. We also discussed how we can extend, or inherit, new entities from existing ones and use them in our applications.

In the next chapter of this book, we will take a look at WCF Data Services and learn how we can use them with Entity Framework in our applications.
