Definition of context

An ordered sequence of properties that define an environment for the objects resident inside it. Contexts are created during the activation process for objects that are configured to require certain automatic services such as synchronization, transactions, just-in-time activation, security, and so on. Multiple objects can live inside a context.

A structure in the Entity Framework that represents the entity container that contains a connection to the underlying data source and provides services such as change tracking and identity resolution. A context is represented by an instance of the DbContext or ObjectContext class.
