![]() ![]() In the above example, entityList is a type of List. or // context.AddRange(std1, std2, computer) Using ( var context = new SchoolContext()) Disconnected entity var std = new Student() The following example demonstrates inserting a new record into the database using the above steps: Attach an entity to DbContext with an appropriate EntityState e.g.The following steps must be performed in order to insert, update or delete records into the DB table using Entity Framework Core in disconnected scenario: The following figure illustrates the CUD operations in disconnected scenario:Īs per the above figure, disconnected entities (entities which are not being tracked by the DbContext) need to be attached to the DbContext with an appropriate EntityState.įor example, Added state for new entities, Modified state for the edited entities and Deleted state for the deleted entities, which will result in an INSERT, UPDATE, or DELETE command in the database when the SaveChanges() method is called. So, you need to attach the disconnected entities to a context with appropriate EntityState in order to perform CUD (Create, Update, Delete) operations to the database. In the disconnected scenario, the DbContext is not aware of disconnected entities because entities were added or modified out of the scope of the current DbContext instance. Saving data in the disconnected scenario is a little bit different than in the connected scenario. Here, you will learn about saving data in the disconnected scenario. You learned about how to save data in the connected scenario. ![]() Next Insert Data in Disconnected Scenario in Entity Framework Core ![]()
