hi all, am trying to implement multiple languages for my project. 

so am following this article http://jondjones.com/creating-a-multi-language-picker-in-episerver/.

when i am implemented code like above am getting error. the error is 

No default Instance is registered and cannot be automatically determined for type 'EPiServerSites.Business.ContentRepository.IContentRepositoryFactory'

There is no configuration specified for EPiServerSites.Business.ContentRepository.IContentRepositoryFactory

1.) new EpiServerDependencies(*Default of IContentRepositoryFactory*, *Default of ILinkResolverFactory*, *Default of IContextResolverFactory*)
2.) EPiServerSites.Business.EpiServerDependencies
3.) Instance of EPiServerSites.Business.EpiServerDependencies
4.) Container.GetInstance(EPiServerSites.Business.EpiServerDependencies)

 am getting this error at BaseBlockController.

am using StructureMapDependencyResolver which is came predefind.

and both class files are below.

namespace EPiServerSites.Business.ContentRepository
{
    public interface IContentRepositoryFactory
    {
        IContentRepository GetContentRepository();
    }
}
namespace EPiServerSites.Business.ContentRepository
{
    public class ContentRepositoryFactory : IContentRepositoryFactory
    {
        internal Injected ContentRepositoryService;
        public IContentRepository GetContentRepository()
        {
            return ContentRepositoryService.Service;
        }
    }
}
Base block controller is 
 public abstract class BaseBlockController : BlockController
        where TBlockData : BlockData
    {
        private Injected epiServerDependencies;
        private Injected routeHelper;
        [DefaultConstructor]
        public BaseBlockController()
        {
        }
        protected PageData CurrentPage
        {
            get
            {
                return routeHelper.Service.Page;
            }
        }
        protected EpiServerDependencies EpiServerDependencies
        {
            get
            {
                var value = epiServerDependencies.Service;
                value.CurrentPage = CurrentPage;
                return value;
            }
        }
    }
