在 VS2017 中手动创建 MFC 应用程序

问：

我正在尝试在 VS2017 下编译一个 MFC 应用程序。

我从一个空的 C++ 项目创建了这个应用程序。

#include <afxwin.h>

class CMyApp : public CWinApp
{
public:
    virtual BOOL InitInstance()
    {
        CFrameWnd* pFrame = new CFrameWnd;
        if (!pFrame)
            return FALSE;

        pFrame->Create(NULL, _T("Minimal MFC Application"));
        m_pMainWnd = pFrame;
        pFrame->ShowWindow(SW_SHOW);
        pFrame->UpdateWindow();

        return TRUE;
    }
};

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    CMyApp app;
    AfxWinInit(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
    return app.Run();
}

然后我通过链接添加了 和 。nafxcwd.liblibcmtd.lib

然后我设置

• MyProjet -> Properties -> Configuration Properties -> C/C++ -> Code Generation -> Runtime Library -> Debug = /MDd
• MyProjet -> Properties -> Configuration Properties -> C/C++ -> Code Generation -> Runtime Library -> Release = /MD

现在，我收到以下错误：

1>------ Rebuild All started: Project: Project2, Configuration: Debug Win32 ------
1>Source.cpp
1>_WIN32_WINNT not defined. Defaulting to _WIN32_WINNT_MAXVER (see WinSDKVer.h)
1>nafxcwd.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in libcmtd.lib(delete_scalar.obj)
1>C:\Users\pc\source\repos\Project2\Debug\Project2.exe : fatal error LNK1169: one or more multiply defined symbols found
1>Done building project "Project2.vcxproj" -- FAILED.
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

如何解决此错误？
