已经用Google搜索了几个小时来解决此错误并发现很多人都会收到此错误，但还没有为我自己的案例找到解决方案。
大多数情况下，解决方案是将SubSystem更改为解决方案属性中的相应选项，可以是Console或Windows。但我的设置为windows，这是我的正确选择。
当我创建此解决方案时，我使用了File＆gt;新＆gt;项目＆gt; Win32项目＆gt; （已选择）Windows应用程序＆gt; （选中）空项目
我的字符集设置为Unicode，我认为是默认值。
这是我的代码，main.cpp：

您将WinMain放入C ++命名空间。 WinMain()必须是全局命名空间中的自由函数，而不是应用程序命名空间中的自由函数。
