我的项目和 Web 服务在模拟器中运行良好，但在上传到 iPhone 时崩溃。在我从 1.1 更新 Monotouch 之前，它一直运行良好。我可以恢复到早期版本的 Monotouch 吗？这是问题所在：
我有一个使用网络服务的单点触控应用程序。当我将项目导出到 Xcode 时，我收到一个构建错误，指出：
System.Web.Services.dll.mdb: No such file or directory
在文件夹资源管理器中，该文件以红色突出显示，因为那里没有任何内容。
有人有最新版本的 monodevelop 和 monotouch 的可用 System.Web.Services.dll 吗？
这是xCode中退出错误的堆栈跟踪：

使用您的 Web.Services.dll 我想我得到了一个较短的堆栈跟踪错误。
