We just released Aspose.Network for .NET v4.4.0.0.

Many new features and enhancements are included in this new version, like sending appointments in email messages. Now you can send an appointment request in email, update the appointment or cancel the appointment. Here is the sample code:

Request Apoinment

       MailMessage msg = new MailMessage();  
        msg.From = "[organizer@aspose.com](mailto:organizer@aspose.com)";  
         
        //attendees for the event  
        MailAddressCollection attendees = new MailAddressCollection();  
        attendees.Add(new MailAddress("[attendee1@aspose.com][1]);  
        attendees.Add(new MailAddress("[attendee2@aspose.com][2]);  
        attendees.Add(new MailAddress("[attendee3@aspose.com][3]);  
        msg.To = attendees;

        DateTime dtstart = new DateTime(2008, 12, 24, 14, 30, 0);

        //create calendar  
        Appointment appoinment= new Appointment(  
            "Room 112",  
            "Product Release meeting",  
            "Product release meeting",  
            dtstart,  
            dtstart.AddHours(1),  
            msg.From[0],  
            attendees);

        string uniqueId = "f6bd236b-a48b-4eb5-a9ec-2177a77bd2f4";  
        appoinment.UniqueId = uniqueId;  
        msg.Subject = "Release Meeting";

        //add the appointmentto mail message  
        msg.AddAlternateView(appoinment.RequestAppointment(0));

Update Appoinment
//set the uniqueid of the appointment
string uniqueId = “f6bd236b-a48b-4eb5-a9ec-2177a77bd2f4”;
appoinment.UniqueId = uniqueId;

        //send appointment with 1 as sequence id  
        msg.AddAlternateView(appoinment.UpdateAppointment(1));

Cancel Appoinment

       //set the uniqueid of the appointment  
       string uniqueId = "f6bd236b-a48b-4eb5-a9ec-2177a77bd2f4";  
       appoinment.UniqueId = uniqueId;

        //send cancel appointment with 2 as the sequence id  
        msg.AddAlternateView(appoinment.CancelAppointment(2));
