C# IronRuby、DLR、范围包含

我想做的是将正在运行的应用程序的AppDomain引入加载的（Iron）Ruby脚本

下面是我想要实现的一个例子：

using System;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using IronRuby;

namespace Testing
{
    public class MainClass
    {
        public MainClass() { }
        public override string ToString() { return "Hello World"; }
        public static void Main()
        {
            ScriptEngine engine = IronRuby.Ruby.CreateEngine();
            ScriptScope scope = engine.CreateScope();
            String code = "p Testing::MainClass.new.to_str";
            ScriptSource script = engine.CreateScriptSourceFromString(code, SourceCodeKind.SingleStatement);
            script.Compile();
            script.Execute(scope);
        }
    }
}

当然，代码不起作用，因为IronRuby引擎中没有加载AppDomain或作用域（我不确定实际是什么）

所以问题是，如何使代码工作（打印“Hello World！”）？

现在，我们可以在运行时加载程序集：

using System;
using System.Reflection;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using IronRuby;

namespace Testing
{
    public class MainClass
    {
        public MainClass() { }
        public override string ToString() { return "Hello World"; }
        public static void Main()
        {
            ScriptEngine engine = IronRuby.Ruby.CreateEngine();
            engine.Runtime.LoadAssembly(Assembly.LoadFile(Assembly.GetExecutingAssembly().Location));
            ScriptScope scope = engine.CreateScope();
            String code = "p Testing::MainClass.new";
            ScriptSource script = engine.CreateScriptSourceFromString(code, SourceCodeKind.SingleStatement);
            script.Execute(scope);
        }
    }
}

能否更新此示例以与Windows Phone Visual Studio 2012兼容？因为我在C#Windows Phone项目中尝试使用IronRuby时会出错。
