Using Umbraco's service APIs

    Whenever you need to modify an entity that Umbraco stores in the database - there is a service API available for it. This means that you can create, update and delete any of the core Umbraco entities directly from your custom code.

    Accessing the Umbraco services.

    To use the service APIs - you must first access them. This is done through what is know as ApplicationContext which provides access to everything related to the Umbraco application.

    Access via Controller

    If accessing Umbraco services inside your own controller class - then by inheriting from one of Umbraco's base controller classes you get access to all services through Services:

    public class EventController : Umbraco.Web.Mvc.SurfaceController
        public Action PerformAction()
           var content = Services.ContentService.GetById(1234);

    Access via ApplicationEventHandler

    If we for instance subscribe to the ApplicationStarted event - we get access to this context - which then provides a .Services class which contains all the available services

    public class EventHandler : Umbraco.Core.ApplicationEventHandler
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            var c = applicationContext.Services.ContentService.GetById(1234);

    Services available

    There is full api coverage of all Umbraco core entities:
