OWIN DbContext and a single DbContext for all of my Repositories

问题

I am building a ASP.NET MVC application. I'm new to the whole Repositories/Unit Of Work patterns. I'm part way through implementing a generic repository for my EF objects.

I realise that there is an issue with ensuring that you only have a single DbContext per Http request... I'm pretty sure that I can achieve this by creating an instance using OWIN.

    /// <summary>
    /// Configures OWIN
    /// </summary>
    /// <param name="app"></param>
    public void Configuration(IAppBuilder app)
    {
        // Create instance of database context
        app.CreatePerOwinContext<QuizEntitiesDbContext>(GetQuizEntitiesDbContext);
    }

    /// <summary>
    /// Returns an instance of the QuizEntitiesDbContext database context
    /// </summary>
    /// <returns></returns>
    public static QuizEntitiesDbContext GetQuizEntitiesDbContext()
    {
        return new QuizEntitiesDbContext();
    }

Now that seems fine if I want to get that instance within my controller, but really I need to be able to access this instance through my generic repository...

Is there a way that this can be achieved?

I'm also using Ninject dependency injector in my project and I've read that I can get an instance of objects per HTTP request for use in my application, something along the lines of this:

this.kernel.Bind(IMyDbContext).To(MyDbContext).InRequestScope();

Should I be using this/OWIN or both?
Do I need to wrap my DbContext in an interface or something?
