    DI Registration WithParameter

    Hi all,
    I wish to register an object with DI where one parameter comes from the container, and the other is specified at registration time.

    I have a class for which the constructor takes 2 parameters like so:

    public PriceCache(string relativeDiskCachePath, DynamicsPriceRepository priceRepo)

    In Umbraco 7 I could register that with the DI container like so:

            builder.RegisterType<DynamicsPriceRepository>();
        builder.RegisterType<PriceCache>()
               .WithParameter("relativeDiskCachePath", "~/App_Data/DynamicsCache/Prices")
               // other constructor parameter injected automatically.
               .SingleInstance();

    How would I do this in Umbraco 8?

    I got around it by making the string constructor param a type I could register instead of a string, And registered it like so:

            composition.Register<DynamicsPriceRepository>(Lifetime.Singleton);
        composition.RegisterUnique(new PriceCacheConfiguration(){RelativeDiskCachePath = "~/App_Data/DynamicsCache/Prices" });
        composition.Register<PriceCache>(Lifetime.Singleton);
