MonoTouch 4.2 在设备上运行时不支持 System.ServiceModel.EndpointAddress()（适用于模拟器）

Question

我正在使用 MonoTouch 4.2.1 与 MonoDevelop 2.8 Beta 2 和 XCode 4。我们正在尝试通过 slsvcutil 代理生成器生成的类调用 .Net Web 服务方法。

在 iPhone 模拟器上测试应用时，代码运行正常，我们成功连接到服务器并发送 Web 服务请求。

但是，在设备上测试应用程序（iPhone 4 和 iOS 4.3.5）时，调用 System.ServiceModel.EndpointAddress() 构造函数时应用程序无法连接到服务器。

请注意，它在 MonoTouch 4.0.7 上运行良好。

我们得到错误：

Attempting to JIT compile method 'System.Linq.Enumerable:FirstOrDefault<System.ServiceModel.Description.OperationDescription> (System.Collections.Generic.IEnumerable`1<System.ServiceModel.Description.OperationDescription>,System.Func`2<System.ServiceModel.Description.OperationDescription, bool>)' while running with --aot-only.

下面这行似乎崩溃了：

new System.ServiceModel.EndpointAddress(
      string.Format(System.Globalization.CultureInfo.InvariantCulture, "http://{0}:{1}/Dartfish/RemoteControlServices/",
      address, port)));

错误堆栈：

这似乎不是编译器问题，因为编译器选项应该是“仅链接 SDK 程序集”。 有人知道如何修复此崩溃，或者是否是新的 MonoTouch 限制/上一个 MonoTouch 版本中的错误？

有人知道如何修复此崩溃，或者是否是新的 MonoTouch 上一个 MonoTouch 版本的限制/错误？

您是否尝试过当前版本和/或联系过 MonoTouch 的支持人员？您唯一的问题似乎最好针对 MonoTouch 的支持人员，而不是这里。
