Hi, Dan Diplo.

Thank you for the response.

It was helpful for me.

Also for solution I used next link

Wrote simple like this:

using Umbraco.Core;
using Umbraco.Web;
using umbraco.BusinessLogic;
using umbraco.cms.businesslogic;
using umbraco.cms.businesslogic.web;

namespace Umbraco.Extensions.EventHandlers
{
    public class RegisterEvents : IApplicationEventHandler
    {
        public void OnApplicationInitialized(UmbracoApplicationBase httpApplication, ApplicationContext applicationContext)
        {            
        }

        public void OnApplicationStarting(UmbracoApplicationBase httpApplication, ApplicationContext applicationContext)
        {
            Document.BeforePublish += Document_BeforePublish;
        }

        public void OnApplicationStarted(UmbracoApplicationBase httpApplication, ApplicationContext applicationContext)
        {
        }

        private void Document_BeforePublish(Document sender, PublishEventArgs e)
        {
            //Custom code
        }
    }
}
