Hinweise

The MergeSubscription class is used with both pull and push subscriptions to a merge publication.

When configuring a Publisher with a remote Distributor, the values supplied for all parameters, including SynchronizationAgentProcessSecurity, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before calling the Create method. For more information, see Verschlüsseln von Verbindungen zu SQL Server.
