Entity Framework 4.1 default eager loading

I'm using Entity Framework 4.1 code first approach.

I want to make eager loading as my the dafault configuration, and by that avoid using the Include extension method in each fetching query.

I did as recomended in MSDN, changing the simple lazy property at the DbContext constructor:

public class EMarketContext : DbContext
{
    public EMarketContext()
    {
        // Change the default lazy loading to eager loading
        this.Configuration.LazyLoadingEnabled = false; 
    }
}

unfortunately, this approach is not working. I have to use the Include method to perform eager loading in each query. Any ideas why? Thanks in advance.
