WebAPI:
public IEnumerable PostProducts([FromBody]IEnumerable pList)
{
     return repository.AddProducts(pList);
}
Client
private static async Task> postProducts () // add product collection
{
   HttpClient client = new HttpClient();
   List products = new List();
   Product p1 = new Product();
   p1.Name = "Product4";
   p1.Price = 111.1M;
   p1.Category = "Condiments";
   products.Add(p1);
   Product p2 = new Product();
   p2.Name = "Product5";
   p2.Price = 222.2M;
   p2.Category = "Hardware";
   products.Add(p2);

   // need to add controller method name based on changes to routing in WebApiConfig.cs
   response = await client.PostAsJsonAsync>(serviceUrl + @"/PostProducts", products);

   if (!response.IsSuccessStatusCode)
   {
       Console.WriteLine("ERROR:  Products Not Posted." + response.ReasonPhrase);
       return null;
   }
   products = await response.Content.ReadAsAsync>();

   return products; //
}
