Please see the following code. I want to make sure I'm implementing async and await correctly. This concept is new to me.
I'm using MVC to consume a Web Api service.

        // GET: Products/ProductsByCategory/5
        public async Task<ActionResult> ProductsByCategory(int id)
        {
            string url = string.Format("{0}api/categories/{1}/products", baseUrl, id);
            Service<GetProductsByCategoryID> service = new Core.Service<GetProductsByCategoryID>(url);
            return PartialView(await service.GetListAsync());
        }

        public async Task<List<T>> GetListAsync()
        {
            using (HttpClient client = new HttpClient())
            {
                client.BaseAddress = new Uri(url);

                return JsonConvert.DeserializeObject<List<T>>(
                    await client.GetStringAsync(url)
                );
            }
        }

P.S.

One thing to note--slightly off-topic--is that HttpClient is designed to be reused for multiple requests. So rather than wrapping your instance in a using you might consider widening the scope of that variable such that you can re-use the single instance across requests.

Thank you for your replies.
Also, thank you for the suggestion regarding HttpClient and being reused. Most of the examples I have seen use the using block.

But now I have located some topics regarding HttpClient and re usability.
