Question

I have a single controller that I want to use for CRUD operations on two different entities which implement the same interface. I’d like for Ninject to give it a different repository based on a query string value in the URL (or maybe a different URL, routed to the same controller). Is this possible? How can I do it?

That’s usually a design smell but you could define the binding like this:

kernel.Bind<IRepo>().ToMethod(ctx => 
{
    var a = HttpContext.Current.Request["a"];
    if (a == "b")
    {
        return new RepoA();
    }

    return new RepoB();
}).InRequestScope();
