using System.Threading;

class Test
{
    static void Main()
    {
        SecurityContext.Run(SecurityContext.Capture(), 
            new ContextCallback(Callback), "Hello world.");
    }
    static void Callback(object o)
    {
        Console.WriteLine(o);
    }
}

Imports System
Imports System.Security
Imports System.Threading



Class Test
    
    Shared Sub Main() 
        Dim cCallBack As New ContextCallback(AddressOf Callback)
        SecurityContext.Run(SecurityContext.Capture(), cCallBack, "Hello world.")
    End Sub 'Main
    
    Shared Sub Callback(ByVal o As Object)
