CS-Script 2.7.0

Autoclass

In this mode the script engine automatically generates wrapper class if the script does not define any class of its own.

This feature is a light weight flavor of the Classless Scripts support. The important difference is that Autoclass support is a native (embedded) feature of the script engine and does not require any external file to work (Clssless Scripts require Alternative Compiler implemented as a separate assembly).
Script.cs:

using System; void Main() {     Console.WriteLine("Hello World!"); }

The script above at runtime willl be interprited as following:

using System; public class ScriptClass {     static void Main()     {         Console.WriteLine("Hello World!");     } }

Note: the /autoclass switch does not interfire with execution of normal class containing scripts.
