The services namespace provides runtime services, such as email processing, alert management, and task-scheduling.

Services are defined in metadata and can contain properties for configuration. A Service references a component and that component must implement the IServiceInfo interface.

Services can be marked as Singleton. This means that the application context object will create only one instance of the service for the life of the application.

  • DBDocStorageViaMapper - Documents are stored in a database using an IMapper configured on the service.
  • S3DocumentStorage - Documents are ultimately stored in Amazon Simple Storage Service (Amazon S3) with local database caching.

The following example shows how to obtain a reference to the email service and send a message using a template.
 Copy imageCopy
private void Send(IAppContext appContext, string sendToList, string templateName, NameValueCollection nameValues)
    ServiceInfos        svs = appContext.Services;
    IEmailService        mail = (IEmailService)svs.GetServiceInstance("SmtpMail");            
    NetQuarry.Template    tmpl = appContext.Templates[templateName];
    string                body;
    string                subject;

    if (tmpl == null)
        throw new ApplicationException(string.Format(this.TextItems.GetText(IDS_MISSING_TEMPLATE), templateName));

    body = tmpl.Replace(nameValues);
    subject = tmpl.TextItems.GetText("Subject");

        //--- leave the From field empty, it will default to the value configured in the studio
        mail.Send(string.Empty, sendToList, subject, body, true);
    catch(Exception ex)
        //--- log the error then re-throw
        DevLog.LogMessage("XIssue.Send", "sendMailError", ex);
