How to use WebClient to call remote webservice from C# Bpmonline class?



When we code that :



            HttpClient client = new HttpClient();

            client.BaseAddress = new Uri(UrlMiddleware);

            client.DefaultRequestHeaders.Accept.Clear();

            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpResponseMessage response = client.GetAsync("api/customers").Result;


Bpm online can't "publish" because it send that error:

The type or namespace name 'Http' does not exist in the namespace 'System.Net' (are you missing an assembly reference?)

but i have added using's:

    using System.Net.Http;
    using System.Net.Http.Headers;

Have you a idea please?
