Get an Instance using Ninject

Question

How can I get a single instance using Ninject? Here's my Service Module:

public class ServicesModule : NinjectModule
{
    public override void Load()
    {
        Kernel.Bind<IDocumentServiceApi>().To<DocumentServiceApi>().InRequestScope();
        Kernel.Bind<IConfigurationService>().To<ConfigurationService>().InRequestScope();
        Kernel.Bind<IReportGenerationProcessor>().To<ReportGenerationProcessor>().InRequestScope();
    }
}

I need an instance of IReportGenerationProcessor to fire off a message I am receiving from an Azure Service Bus Queue.

I've seen a lot of different ways, but none have worked for me. I constantly get the error :Object instance not set to an instance of an object.

//I do instantiate this class using new WebJobBase();
public class WebJobBase
    {
        public void ProcessMessage(BrokeredMessage message)
        {
                // Just need an instance of IReportGenerationProcessor here
                var _processor = new ReportGenerationProcessor();
                _processor.ProcessMessage(message);
        }
    }

Here's my IReportGenerationProcessor implementation:

    public interface IReportGenerationProcessor
    {
        DocumentMetaData ProcessMessage(BrokeredMessage message);
    }
    public class ReportGenerationProcessor : IReportGenerationProcessor
    {
        // Go figure these don't work either
        [Inject]
        public IConfigurationService _config { get; set; }
        [Inject]
        public IDocumentServiceApi _docService { get; set; }

        public DocumentMetaData ProcessMessage(BrokeredMessage message)
        {
            var report = message.GetBody<ReportMetaData>();

            //Do some stuff
            return new DocumentMetaData(); // just a place holder
        }
    }

If I can provide more information, please let me know. I'm not too knowledgeable on Ninject.

Okay, so the documentation kind of hinted at this, but they didn't use an Interface and registered .ToSelf().

Basically I needed to instantiate a new StandardKernel with my ServicesModule from above, and call the .Get<>(); method for my registered Interface.

IKernel kernel = new StandardKernel(new ServicesModule());
var processor = kernel.Get<IReportGenerationProcessor>();
processor.ProcessMessage(message);
