PrePersistChangeState

Gets or sets the change state of the entity before persisting to the data store.

Declaration
ChangeState PrePersistChangeState { get; set; }
Property Value
Type Description
ChangeState

The change state.
Remarks

This value is typically used in the post processing part of the persist behavior (AfterPersistAsync(Object, IEntityEntry, IDataOperationContext, CancellationToken)) to perform specific tasks depending on the value of ChangeState before persisting to the data store. Outside this behavior this value is not reliable, as the behaviors may trigger multiple persist commands for an entity and this state is typically the value before the last persist command.
