[StoreLoader("sample")]
private static (IStore Store, IStateStore StateStore) Loader(Uri storeUri)
{
    NameValueCollection query = HttpUtility.ParseQueryString(storeUri.Query);
    int cache = query.GetInt32("cache", 128);
    var store = new SampleStore(storeUri.LocalPath, cache);
    var stateStore = new SampleStateStore(storeUri.LocalPath, cache);
    return (store, stateStore);
