Initialization system

You can develop your own initialization module, see Initialization.

The initialization system consists of the following:

A discovery mechanism to determine which modules should be part of the initialization process.
A dependency sorting algorithm that decides the order of execution.
An execution engine that executes the modules.
Handling of re-execution of initialization modules (by hooking into ASP.NET) in the occurrence of exceptions during startup.
The EPiServer.Framework.Initialization namespace, which resides in the assembly EPiServer.Framework.

Sample initialization module

The following sample initialization module takes a dependency to the EPiServer.Commerce.Initialization.InitializationModule and registers catalog content routes.

using System.Web.Routing;
using EPiServer.Framework;
using EPiServer.Commerce.Routing;
using EPiServer.Framework.Initialization;

namespace CodeSamples.EPiServer.Commerce.Catalog
  {
    [ModuleDependency(typeof(global::EPiServer.Commerce.Initialization.InitializationModule))]
    public class RegisterRoutingModuleSample : IInitializableModule
      {
        public void Initialize(InitializationEngine context)
          {
            MapRoutes(RouteTable.Routes);
          }
        private static void MapRoutes(RouteCollection routes)
          {
            CatalogRouteHelper.MapDefaultHierarchialRouter(routes, true);
          }
        public void Uninitialize(InitializationEngine context) { /*uninitialize*/}
        public void Preload(string[] parameters) { }
      }
  }
