Execute C# in PowerShell: errors with " using System.XML "

Question

Hi , I'm trying to execute C# code in Power Shell 2.0 .
My problem is for the references  at the beginning of the code:
$code = @"
using System;
using System.Collections;
using System.IO;
using System.Linq;
using System.Xml;
using System.Xml.Linq;
   public class Program
        static void Main()
        {  /* the code wich works*/
Add-Type  -TypeDefinition $code -Language "CSharpVersion3"
Powershell give me an error saying that " The type or namespace Linq doesn't exist" , and the same for Xml. I have Visual studio express 2013 .
How can add or import correctly those references? or what is my error?

Hi Rebegg,
As this issue is related to Visual Studio, I suggest you create a new thread on Visual Studio forum, more experts will assist you with this issue.

In addition, about this issue, you have to add your  assemblies to your PowerShellsession before you can reference them to you C# Code, you can use the script like:
$Assem = (
...add referenced assemblies here...
$Source = @"
...add C# source code here...
Add-Type -ReferencedAssemblies $Assem -TypeDefinition $Source -Language CSharp
