string publicationDbName = "AdventureWorks";

TransPublication publication;

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

    conn.Connect();

    // Set the required properties for the publication.
    publication = new TransPublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;

    // If we can't get the properties for this publication, 
    // throw an application exception.
    if (publication.LoadProperties())
    {
        // Initiate validataion for all subscriptions to this publication.
        publication.ValidatePublication(ValidationOption.RowCountOnly,
            ValidationMethod.ConditionalFast, false);

        // If not already running, start the Distribution Agent at each 
        // Subscriber to synchronize and validate the subscriptions.
