Remarks

The Add method adds an object to the related end. The related end must be an EntityCollection<TEntity>.

When the source object implements IEntityWithRelationships and is being tracked in the ObjectStateManager, the object being added is also tracked.

The RelatedEnd class explicitly implements the Add method. The EntityCollection<TEntity> class uses this implementation. For more information, see Add.

If the related end is an EntityReference<TEntity> and the Value property of the reference is not null, this method throws an exception.
