Создать клиент API для приложения Azure API, которое предоставляет и метод загрузки файла

Question

Привет у меня есть приложение Azure API (Asp.net MVC), который предоставляет следующий метод на контроллере

[HttpPost, Route("api/upload")]
        public async Task<IHttpActionResult> Upload()
        {
            if (!Request.Content.IsMimeMultipartContent())
                throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);

            var provider = new MultipartMemoryStreamProvider();
            await Request.Content.ReadAsMultipartAsync(provider);
            foreach (var file in provider.Contents)
            {
                var filename = file.Headers.ContentDisposition.FileName.Trim('\"');
                var buffer = await file.ReadAsByteArrayAsync();
                //Do whatever you want with filename and its binaray data.
            }

            return Ok();
        }

затем я генерирую остальные API-клиент, пока все работает хорошо, но сгенерированный код не запрашивает никаких параметров, так как я могу загрузить файл (ы), это сгенерированные методы на стороне клиента

 /// <param name='operations'>
            /// The operations group for this extension method.
            /// </param>
            public static object Upload(this IValues operations)
            {
                return Task.Factory.StartNew(s => ((IValues)s).UploadAsync(), operations, CancellationToken.None, TaskCreationOptions.None, TaskScheduler.Default).Unwrap().GetAwaiter().GetResult();
            }

            /// <param name='operations'>
            /// The operations group for this extension method.

                tracingParameters.Add("cancellationToken", cancellationToken);

Любой совет, как я могу использовать приведенный выше код для загрузки файлов?
