通过SMO访问Azure SQL Server会抛出TransferException

我试图将一个Azure SQL数据库复制到位于同一服务器上的另一个数据库。我正在使用SMO (System.Data.SqlClient)进行此操作。我知道这不是最有效的方法，但是我的意图是利用这个脚本在我的本地SQL服务器上创建我的Azure SQL数据库的预定副本。

这是我的代码(Dev是原始数据库，Dev- mirror是目标数据库):

var serverConnection = new ServerConnection();
        serverConnection.NetworkProtocol = NetworkProtocol.TcpIp;
        serverConnection.ConnectionString = "Server=tcp:mysernamename.database.windows.net,1433;User ID=user@server;Password=password;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;";
        var server = new Server(serverConnection);
        var transfer = new Transfer(server.Databases["Dev"]);
        transfer.CopyAllObjects = true;
        transfer.CopyAllUsers = true;
        transfer.Options.WithDependencies = true;
        transfer.DestinationDatabase = server.Databases["Dev-Mirror"].Name;
        transfer.DestinationServer = server.Name;
        transfer.DestinationLoginSecure = true;
        transfer.CopySchema = true;
        transfer.CopyData = true;
        transfer.Options.ContinueScriptingOnError = true;
        transfer.TransferData();

大约两分钟后，这段代码在执行TransferData之后抛出以下TransferException(但是，到服务器本身的连接成功，并且填充了server实例上的Databases属性):
