What is change tracker in Entity Framework?

By delinquency Entity Framework traces alterations of the filled entities throughout the lifespan of the context. A change tracker traces alteration when one adds new records, deletes or updates the existing records. It offers one all the details and information regarding updated entities being traced by the context and all the alterations are collected by the Dbcontext level.

Hence, the change tracker offers access to alter tracking operations and information for entity instances of the context which is being traced. Instances of these classes are usually taken from change tracker and which are not developed to be directly created in one's application codes.
