Compiler Warning (level 4) CS0028 

Error Message

'function declaration' has the wrong signature to be an entry point

The method declaration for Main was invalid: it was declared with an invalid signature. Main must be declared as static and it must return either int or void. For more information, see Main() and Command Line Arguments (C# Programming Guide).

The following sample generates CS0028:

// CS0028.cs
// compile with: /W:4 /warnaserror
public class a
{
    public static double Main(int i)   // CS0028
    // Try the following line instead:
    // public static void Main()
    {
    }
}
