The method is used to apply changes that were made to objects outside the ObjectContext, such as detached objects that are received by a Web service. The method copies the scalar values from the supplied object into the object in the ObjectContext that has the same key. You can use the EntityKey of the detached object to retrieve an instance of this object from the data source. For more information, see How to: Return a Specific Object Using its Key (Entity Framework). Any values that differ from the original values of the object are marked as modified. Note, the method does not apply the current values to the related objects of currentEntity.
If you have a graph with the current values and want to apply the original values, call ApplyOriginalValues<TEntity> method.
