    MVC v4.10.1 IoC with Unity

    Hi,

    I am just trying to use dependency injection with Unity base on this docu: https://github.com/umbraco/Umbraco4Docs/blob/master/Documentation/Reference/Mvc/using-ioc.md

    Within the SurfaceController class only the default constructor gets called so the dependency resolving never takes place. The YOD says: System.MissingMethodException: No parameterless constructor defined for this object.
    What is missing here?

    Btw: I have installed the Unity.Mvc3 package and try to register a simple test class with in Unity
    This does basically something like documented here http://www.codeproject.com/Articles/118881/Dependency-Injection-in-MVC-3-Was-Made-Easier
    and works fine in a plain VStudion MVC3 project.

    Yours,
    Dirk

    I found a solution for my problem. The new way to hook into the application start seems to be implementing the IApplicationEventHandler like so:

    namespace MvcUmb410plus
{
    public class MyApplication : Umbraco.Web.IApplicationEventHandler
    {

 #region IApplicationEventHandler Member


        public void OnApplicationStarted(UmbracoApplication httpApplication, Umbraco.Core.ApplicationContext applicationContext)
        {
            Bootstrapper.Initialise();
        }

        public void OnApplicationInitialized(UmbracoApplication httpApplication, Umbraco.Core.ApplicationContext applicationContext)
        {
        }

        public void OnApplicationStarting(UmbracoApplication httpApplication, Umbraco.Core.ApplicationContext applicationContext)
        {
        }

 #endregion
    }

    //public class MyApplication : Umbraco.Web.UmbracoApplication
    //{
    //  protected override void OnApplicationStarted(object sender, EventArgs e)
    //  {
    //    base.OnApplicationStarted(sender, e);
    //    Bootstrapper.Initialise();
    //  }

    //}
}

    Well, its just another example of missing something...

    The documentation does work. The only thing I have missed was to chnage the inherits clause / parameter in the global.asax like so:

    <%@ Application Codebehind="Global.asax.cs" Inherits="MyProject.MyApplication" Language="C#" %>

    Did you have also the problem that the OnApplicationInitialized, OnApplicationStarting & OnApplicationStarted runs twice? If i put a debugger on the project i see two hits on the same code..
