I just discovered that you may also use the AppDomain.SetData but this is only one way From Host Domain to Child Domain.

static void RunInChildDomain()
{
     AppDomain childDomain = AppDomain.CreateDomain("friendlyName");
     string parameterValue = "notmii";
     childDomain.SetData("parameter", parameterValue);
     childDomain.DoCallBack(PrintName);
}

static void PrintName()
{
     string Name = Convert.ToString(AppDomain.CurrentDomain.GetData("parameter"));
     Console.WriteLine(Name);
}

You can also create exception driven communication between child and host appdomain by using AppDomain.FirstChanceException event :)
