“错误LNK2001：无法解析的外部符号_main”仍然存在

Question

I know similar question is already been made but none of the answers helped me.

I get this error :

MSVCRT.lib(exe_main.obj) : error LNK2001: unresolved external symbol _main

I am using VS17. I created a Wizard Console Application and a Static Lib.

My A.cpp also looks like this

#include <iostream>
#include "A.h"

namespace img{
    int main(int argc, char* argv[]{
        ...
        return 0;
    }
}

I tried changing the Properties of the Project as many suggested but everything looks fine.

根据转换需要在全局名称空间中定义main。
