Or you can do it via SharePoint Object Model:

using (SPSite site = new SPSite(siteURL))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    
               SPList list = web.Lists["Test1"];
               SPUserCustomAction action = list.UserCustomActions.Add();
                    action.Title = "I am unique";
                    action.Description = "Sample Unique ECB";
                    action.ImageUrl = "/_layouts/images/workflows.gif";
                    action.Location = "EditControlBlock";
                    action.Sequence = 0;
                    action.Url = "javascript:alert('I am unique');";
                    action.Rights = SPBasePermissions.ManageLists;
                    action.Update();
                }
            }
