JsonConvert.DeserializeObject（）的System.MethodAccessException

Question

以下代码的JsonConvert.DeserializeObject语句生成异常：

try
{
    string sJOutput = JsonConvert.SerializeObject(dict,
                    new JsonSerializerSettings()
                    {
                        ReferenceLoopHandling = ReferenceLoopHandling.Ignore
                    });
    Debug.WriteLine(sJOutput);
    dict = JsonConvert.DeserializeObject<Dictionary<Guid, MyClass>>(sJOutput);
}
catch (Exception ex)
{
    Debug.WriteLine(ex.Message);
}

例外情况如下：

System.MethodAccessException was caught
  HResult=-2146233072
  Message=Attempt by method 'DynamicClass.lambda_method(System.Runtime.CompilerServices.Closure)' to access method 'System.Xml.Linq.XElement..ctor()' failed.

有人可以提供有关此原因的提示吗？
