You probably have main spelled in lower case. .NET needs it spelled as in the error message above.

I tried "main" , but nothing :(

Of course not, the message tells you that it should be spelled "Main".

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
