From  msdn     When you created the project  you made the wrong choice of application   type  When asked whether your project was a console application or a   windows application or a DLL or a static library  you made the wrong   chose windows application  wrong choice        Go back  start over again  go to File -  New -  Project -  Win32   Console Application -  name your app -  click next -  click   application settings       For the application type  make sure Console Application is selected    this step is the vital step        The main for a windows application is called WinMain  for a DLL is   called DllMain  for a  NET application is called   Main cli  array     and a static library doesn t have a   main  Only in a console app is main called main

I have faced this particular error when I didn t defined the main   function  Check if the main   function exists or check the name of the function letter by letter as Timothy described above or check if the file where the main function is located is included to your project
