在我的手机设备上调试时出现错误，但在模拟器上却没有。每次从服务器（使用 IIS Express 使用 WCF/Odata 托管）请求数据时，它似乎都会出错。相关代码如下（请注意，所有数据访问都会出现问题）：

public void LoadData()
    {
        IsDataLoaded = false;

        string queryUri = string.Format("Jobs?$filter=ApplicantID eq {0}", 1);
        jobData.LoadAsync(new Uri(queryUri, UriKind.Relative));
        jobData.LoadCompleted += new EventHandler<LoadCompletedEventArgs>(jobData_LoadCompleted);
    }

    void jobData_LoadCompleted(object sender, LoadCompletedEventArgs e)
    {
        if (e.Error != null)
        {
            MessageBox.Show(e.Error.Message);
        }
        else
        {
            if (jobData.Continuation != null)
            {
                jobData.LoadNextPartialSetAsync();
            }
        }

        IsDataLoaded = true;
    }

当我使用模拟器时，一切正常，但是当我使用我的 WP7 设备时，我收到一个很大的错误：处理此请求时发生错误

更好的是，内部异常只是说 NotFound。

甚至堆栈跟踪也没有那么有用：

以前有没有人遇到过这个问题并解决了？
