Introduction to detached entities: Entity Framework Core Essential Training: 2

Entities created outside of a DbContext, or loaded from a different DbContext that has gone out of scope, must be attached to a DbContext before EF can persist changes to the underlying data store. This section covers how the entity operations—Add, Update, and Remove—attach entities as well as the special Attach command. The state that gets assigned to an entity when attached depends on the command used and the values of the primary key or keys.
