Filip 831 Reputation points

Hello everybody.

I tried this:

$code = @"  
using System;  
namespace HelloWorld  
 public class Program  
 public static void Main(){  
 Console.WriteLine("Hello world!");  
Add-Type -TypeDefinition $code -Language CSharp  
iex "[HelloWorld.Program]::Main()"  

It work.
But when I change the "$code" variable script and "add-type" it secend time it show me an error.


Why i can't update secend time my script?
How can i do it?

Thanks for help.

    You have to use another type name because it must be unique within a session and can neither be updated nor removed.
