Why is MAIN method always declared as Static in Windows Console Application

While understanding the basic concept of inheritance in internet, i came across a piece of code.

I've seen many people using public static void main().Why dont they simply use public void main() ??What's the advantage of using static here ?

Public class BaseClass
{
    Public BaseClass ()
    {
        Console.WriteLine ("Base Class Constructor executed");
    }
                                 
    Public void Write ()
    {
        Console.WriteLine ("Write method in Base Class executed");
    }
}
                                 
Public class ChildClass: BaseClass
{
                                 
    Public ChildClass ()
    {
        Console.WriteLine("Child Class Constructor executed");
    }
   
    Public static void Main ()
    {
        ChildClass CC = new ChildClass ();
        CC.Write ();
    }
}
