[IronPython] DLR 2.0 Beta 1 can't hosting in another AppDomain

[Andy.Tao]

Hi, 
  
 I have written a DLR hosting application, create ScriptRuntime in another AppDomain, DLR throw exception when execute code. the detail code like follow:
  
 public class ScriptProxy : MarshalByRefObject, IScriptProxy
{
    private ScriptEngine m_ScriptEngine;
    private ScriptRuntime m_ScriptRuntime;
     public ScriptProxy()
    {
        ScriptRuntimeSetup runtimeSetup = new ScriptRuntimeSetup(true);
        m_ScriptRuntime = ScriptRuntime.Create(runtimeSetup);
        m_ScriptRuntime.GlobalOptions.DebugMode = true;
        m_ScriptRuntime.GlobalOptions.DynamicStackTraceSupport = true;
         //Default script engine
        m_ScriptEngine = m_ScriptRuntime.GetEngine("python");
    }
}

//=======Client code as follow =====================

 private void Initialize()
{
    Evidence evidence = AppDomain.CurrentDomain.Evidence;
    AppDomainSetup appSetup = new AppDomainSetup();
    appSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory;
    m_ScriptAppDomain = AppDomain.CreateDomain("ScriptProxy", evidence, appSetup);
     m_ScriptAppDomain.Load("ScriptProxy");
    m_RemoteScript = (IScriptProxy)m_ScriptAppDomain.CreateInstanceAndUnwrap("ScriptProxy", "ZuHong.TestMore.Scripting.ScriptProxy");
}


 m_RemoteScript.ExecuteCode(txtScriptSource.Text);
  
 ==========================================
 DLR throw exception when execute code: SourceUnit not marked as SerializableAttribute.
