Problems with making backup with Firebird package

Question

I'm trying to develop a backup with a firebird database using the firebird package but it gives me an error.

        FbConnectionStringBuilder cs = new FbConnectionStringBuilder();
        cs.UserID = "SYSDBA";
        cs.Password = "masterkey";
        cs.Database = "C:\\Develop\\Database\\DB\\Database.fdb";

        FbBackup backupSvc = new FbBackup();

        backupSvc.ConnectionString = cs.ToString();
        backupSvc.BackupFiles.Add(new FbBackupFile(@"C:\\Develop\\Database\\DB\\Database.fbk", 2048));
        backupSvc.Verbose = true;

        backupSvc.Options = FbBackupFlags.IgnoreLimbo;
        backupSvc.ServiceOutput += new ServiceOutputEventHandler(ServiceOutput);

        backupSvc.Execute();

I cant figure out why I can't compile the following statement: backupSvc.ServiceOutput += new ServiceOutputEventHandler(ServiceOutput);

The errors are:

Error CS0246 The type or namespace name 'ServiceOutputEventHandler' could not be found (are you missing a using directive or an assembly reference?)

and

Error CS0103 The name 'ServiceOutput' does not exist in the current context

Is there anyone who can help?

I found the answer now. My problem is that I have an old version (2.4) of firebird. I upgraded to version 2.9 - and everything works fine. So thank you so much for your assistance. You have all guidet me into the correct direction.
