无法打开包含文件：'cpprest/ws_client'：没有这样的文件或目录

Question

I'm working on a project which is using C++ RESTAPI. Im follwing Casablanca tutorial. According to that tutorial I added Casablanca to my C++ project using NuGet package manager. Im using Visual Studio 2015 Enterprise Edition. But when Including following files it shows error on #include <cpprest/ws_client> . I already set the Additional Include directories, and Additional library Directories form project properties as follows.

Additional Include Directory <project_dir>\\packages\\cpprestsdk.v140.windesktop.msvcstl.dyn.rt-dyn.2.9.1\\build\\native\\include

Additional library Directories <project_dir>\\packages\\cpprestsdk.v140.windesktop.msvcstl.dyn.rt-dyn.2.9.1\\lib

I added actual screen shots here. How to fix this?

#include <iostream>
#include <cpprest/http_client.h>
#include <cpprest/filestream.h>
#include <cpprest/http_listener.h>              // HTTP server
#include <cpprest/json.h>                       // JSON library
#include <cpprest/uri.h>                        // URI library
#include <cpprest/ws_client>                    // WebSocket client
#include <cpprest/containerstream.h>            // Async streams backed by STL containers
#include <cpprest/interopstream.h>              // Bridges for integrating Async streams with STL and WinRT streams
#include <cpprest/rawptrstream.h>               // Async streams backed by raw pointer to memory
#include <cpprest/producerconsumerstream.h>     // Async streams for producer consumer scenarios

using namespace utility;                    // Common utilities like string conversions
using namespace web;                        // Common features like URIs.
using namespace web::http;                  // Common HTTP functionality
using namespace web::http::client;          // HTTP client features
using namespace concurrency::streams;       // Asynchronous streams
using namespace web::http::experimental::listener;          // HTTP server
using namespace web::experimental::web_sockets::client;     // WebSockets client
using namespace web::json;                                  // JSON library 

(I tried with visual Studio 2017,2013 also. But result is same.)

您没有正确包含头文件，因此无法解析引用：使用#include <cpprest/ws_client.h>而不是#include <cpprest/ws_client>对您#include <cpprest/ws_client> 。
