我的项目和网络服务上传到一个iPhone时工作在模拟器，但坠毁的罚款。 它一直工作正常，我从1.1更新的MonoTouch之前。 我能恢复到以前版本的MonoTouch的？ 这里的问题是：
我在使用Web服务的MonoTouch应用程序。 当我将项目导出到Xcode中，我得到一个生成错误，指出：
System.Web.Services.dll.mdb：没有这样的文件或目录
在文件夹资源管理器该文件以红色突出显示，因为没有什么存在。
有没有人有一个工作System.Web.Services.dll为MonoDevelop的和MonoTouch的最新版本？
这是在Xcode中退出错误的堆栈跟踪：

使用您的Web.Services.dll我想我已经找到错误较短的堆栈跟踪。
