Hi all,
I have a c++ dll and a .net core console application which invokes the c++ library and works fine in windows platform. But now I need to do the same in linux platform. Please help how to invoke the dll in .net core to run in linux platform.

Thanks

What I have tried:

[DllImport(@"C:\..\lib\DLLDemo.dll", EntryPoint = "math_add", CallingConvention = CallingConvention.StdCall)]
       public static extern int Add(int a, int b);
       [DllImport("user32.dll")]
       public static extern int MessageBox(IntPtr hWnd, String text, String caption, int options);
       public static void Main(string[] args)
       {
           int result = Add(14, 54);
           Console.WriteLine("result is {0}", result);
           Console.ReadKey();
       }
