Magento REST API GetProducts returns product with 0 attributes count.

[AjoyDeveloper]

I am using Magento REST api into my asp.net application. I want to download all products from my magentohost server to my asp.net C# application, but attributes count return 0 into products details. My code is shown below...

 var client = new MagentoApi()
             .SetCustomAdminUrlPart(AdminUrlPart)
             .Initialize(StoreUrl, ConsumerKey, ConsumerSerect)
             .AuthenticateAdmin(AdminUserName, AdminPassword);

 var filter = new Magento.RestApi.Models.Filter();                
 filter.PageSize = 100;  
 filter.Page = 0;

 var sCode = Task.Run(async () => await client.GetProducts(filter));
 MagentoApiResponse<IList<Magento.RestApi.Models.Product>> product = sCode.Result;

I have also done all setup into magento server. Please tell me what is the reason.
