Hello
i tried using System.Windows.Forms; in my code but it show me an error.
What is wrong, because i want to create the form application using my namespace.
Is it possible to do?
Thanks for help.

$code = @"
using System;
using System.Windows.Forms;
namespace HelloWorld
{
public class Program
{
public static void Main(){
Console.WriteLine("Hello world!");
}
}
}
"@

Add-Type -TypeDefinition $code -Language CSharp
iex "[HelloWorld.Program]::Main()"

I am not familiar with Powershell but I tried your code. For the C# code you have you do not need System.Windows.Forms. So I removed the using for it and then the code works.

Why are you trying to write C# code inside of Powershell? Download the free Visual Studio Community edition and use it to build GUI C# apps. It will be so much easier to develop and test.
