How can I write the Main method
<p>I'm writing a C# program but I don't know where the <code>Main</code> method goes, can someone help me with it?</p>

<pre><code>public abstract class employee
{
    protected int empid;
    protected string empname;
    protected double salarypday;
    public virtual void display(int empid,string empname,double salarypday)
    {
        this.empid = empid;
        this.empname = empname;
        this.salarypday = salarypday;
    }
    public abstract void calsal();
}
public class labassistance : employee
{
    public int labid;
    public void display (int empid,string empname,double salarypday,int labid) :   base(empid,empname,salarypday)
    {

        this.labid = labid;
        Console.WriteLine("lab id is: "+labid);

    }
    public override void calsal()
    {
        double calsalary = (salarypday * 30);
    }
}
</code></pre>
