Commenti

Il gestore della logica di business deve essere registrato nel server di distribuzione e nel Sottoscrittore nel caso di una sottoscrizione pull. Tuttavia, l'assembly che implementa il gestore della logica di business deve essere installato solo nel server in cui viene eseguito il agente di merge.

Il <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> metodo può essere chiamato solo dai membri del ruolo predefinito del sysadmin server e dai membri del ruolo predefinito del db_owner database

La chiamata <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> equivale all'esecuzione di sp_registercustomresolver.
