However i though Microsoft has changed all the assembly names from Microsoft.AspNet to Microsoft.AspNetCore to be more specific with .Net Core framework. But i could not find Microsoft.AspNetCore.WebApi.Client

I dont deserve any credit for this. Have a look @danroth27 answer in the following link.

https://github.com/aspnet/Docs/blob/master/ aspnetcore / mvc / controllers / testing / sample / TestingControllersSample / tests / TestingControllersSample.Tests / IntegrationTests / HttpClientExtensions.cs

他使用扩展方法。代码如下。 （从上面的github链接复制）。我在.Net Core 2.0上使用它。

He uses an extension method. Code as below. (Copied from the above github link). I am using it on .Net Core 2.0.

using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace TestingControllersSample.Tests.IntegrationTests
{
    public static class HttpClientExtensions
    {
        public static Task<HttpResponseMessage> PostAsJsonAsync<T>(
            this HttpClient httpClient, string url, T data)
        {
            var dataAsString = JsonConvert.SerializeObject(data);
            var content = new StringContent(dataAsString);
            content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
            return httpClient.PostAsync(url, content);
        }

        public static async Task<T> ReadAsJsonAsync<T>(this HttpContent content)
        {
            var dataAsString = await content.ReadAsStringAsync();
            return JsonConvert.DeserializeObject<T>(dataAsString);
        }
    }
}
