使用 Windows.Web.Http.HttpClient 类修补异步请求

我需要做一个PATCH请求与Windows.Web.Http.HttpClient类，并且没有关于如何执行此操作的官方文档。我怎样才能做到这一点？

我找到了如何进行“定制”PATCH与上一个请求System.Net.Http.HttpClient class here，然后摆弄直到我让它在Windows.Web.Http.HttpClient类，像这样：

public async Task<HttpResponseMessage> PatchAsync(HttpClient client, Uri requestUri, IHttpContent iContent) {
    var method = new HttpMethod("PATCH");

    var request = new HttpRequestMessage(method, requestUri) {
        Content = iContent
    };

    HttpResponseMessage response = new HttpResponseMessage();
    // In case you want to set a timeout
    //CancellationToken cancellationToken = new CancellationTokenSource(60).Token;

    try {
         response = await client.SendRequestAsync(request);
         // If you want to use the timeout you set
         //response = await client.SendRequestAsync(request).AsTask(cancellationToken);
    } catch(TaskCanceledException e) {
        Debug.WriteLine("ERROR: " + e.ToString());
    }

    return response;
}
