Your first C# Program Tutorial
Description
Let's start by compiling and running the simplest possible C# program.
Source Code
Type the following into a text editor, and save it as First.cs.
using System; /*from w w w. ja v a2s. co m*/
public class MyFirstClass
{
static void Main()
{
Console.WriteLine("Hello from java2s.com.");
Console.ReadLine();

}
}

You can compile this program by simply running the C#
command - line compiler ( csc.exe ) against the
