one option is to implement an ISubDependencyResolver. within the
resolver parse the sport from the current context, then resolve the
repository.
something like
class ProductRepositoryResolver : ISubDependencyResolver
{
public (ProductRepositoryResolver(IKernel kernel)
{
this.kernel = kernel;
}
public object Resolve(...)
{
var sport = parse_sport_from(HttpContext.Current);
return kernel.Resolve<IProductsRepository>(sport);
}
public bool CanResolve(...)
{
return dependency.TargetType == typeof(IProductsRepository);
}
}
register the subdedepency resolver , then you're components. I would
also recommend the fluent API to register the components, rather than
XML.
