Example

// Define the Publisher, publication, and databases.
string publicationName = "AdvWorksSalesOrdersMerge";
string publisherName = publisherInstance;
string subscriberName = subscriberInstance;
string subscriptionDbName = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";

//Create connections to the Publisher and Subscriber.
ServerConnection subscriberConn = new ServerConnection(subscriberName);
ServerConnection publisherConn = new ServerConnection(publisherName);

// Create the objects that we need.
MergePublication publication;
MergePullSubscription subscription;

try
{
    // Connect to the Subscriber.
    subscriberConn.Connect();

    // Define the pull subscription.
    subscription = new MergePullSubscription();
    subscription.ConnectionContext = subscriberConn;
    subscription.PublisherName = publisherName;
    subscription.PublicationName = publicationName;
    subscription.PublicationDBName = publicationDbName;

    // Define the publication.
    publication = new MergePublication();
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;
    publication.ConnectionContext = publisherConn;

    // Delete the pull subscription, if it exists.
    if (subscription.IsExistingObject)
