Question

I have configured Ninject 2 in an ASP.NET 4.0 project (not MVC) however when I deploy the project to an IIS host it crashes with the following:

System.NullReferenceException: Object reference not set to an instance of an object.

[NullReferenceException: Object reference not set to an instance of an object.]
   System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30
   System.Web.PipelineStepManager.ResumeSteps(Exception error) +1481
   System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +132
   System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +709

I have tested this again with a vanilla ASP.net Web Application and get the same crash with the following code:

protected override IKernel CreateKernel()
{
    return Container;
}

private IKernel Container
{
    get
    {
        IKernel kernel = new StandardKernel(new SiteModule());
        var module = new OnePerRequestModule();
        module.Init(this);
        return kernel;
    }
}

Has anyone else got Ninject working with ASP.net 4?

[UPDATE: 2010.11.03]

After doing some research it appears it may be something to do with the OnePerRequestModule() module, removing this however doesn’t seem to resolve the problem I added it due at the suggestion of this question.

Answer 1

In Ninject 2, you use the Ninject.Web extension (see the complete set here) and dont do any explicit config as you have here around OnePerRequestModule etc.

You don’t do any web.config stuff either IIRC (I’m using the MVC one and you don’t there)
