Publication.Create Method

Creates the publication.

Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

public void Create()

ExceptionCondition
ApplicationException

If the publication already exists on the server.

When configuring a Publisher with a remote Distributor, the values supplied for all properties, including SnapshotGenerationAgentProcessSecurity, 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 Encrypting Connections to SQL Server.

The Create method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

Calling the Create method is equivalent to executing sp_addpublication (Transact-SQL) or sp_addmergepublication (Transact-SQL).

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.

This example creates a transactional publication.

			// Create a connection to the Publisher using Windows Authentication.
			ServerConnection conn;
			conn = new ServerConnection(publisherName);

			{
				// Connect to the Publisher.
				conn.Connect();

				// Enable the AdventureWorks database for transactional publishing.
				publicationDb = new ReplicationDatabase(publicationDbName, conn);
