我正在尝试使用 Microsoft EWS 托管 API 构建 iOS 应用程序。我已经从http://www.microsoft.com/download/en/details.aspx?id=13480下载了 msi，并将 DLL 复制到了解决方案文件夹下。在为模拟器构建时，它构建并运行良好，但在尝试针对物理设备时，mtouch 失败并显示：

mtouch exited with code 1

我认真地补充道：

System.DirectoryServices.dll
System.Configuration.dll
System.Security.dll
System.DirectoryServices.Protocols.dll
System.EnterpriseServices.dll

越来越感觉没有走上正轨，但是当 mtouch 抱怨原生 System.EnterpriseServices.Wrapper.dll 时，我放弃了。

我尝试过使用 Project Options/iPhone build SDK 和 Linker 选项。

我还尝试了 32 位和 64 位版本的 Microsoft.Exchange.WebServices.dll

PS 我知道我可以在没有托管 EWS API 的情况下使用 EWS，但是编写和解析所有这些 XML 请求和响应是如此痛苦。

MonoTouch 的链接器和 AOT 编译器在工作时都需要存在所有依赖项。这一点，以及缺少符号（类型、方法...），使得重用来自另一个版本的框架的预构建二进制文件变得困难（但并非完全不可能）。

它还解释了为什么有时（没有丢失的符号）可以在模拟器上工作。默认情况下，模拟器构建设置为“不链接”（无链接器）并使用JIT（无 AOT）。这允许丢失的引用/符号被忽视......直到它们（可能永远不会）需要。

您可以关闭设备构建的链接器 - 但这对 AOT 编译器没有帮助。OTOH，您可以尝试满足链接器的要求，它可以删除足够多的代码以让 AOT 编译器正常工作。可悲的是，当事情归结为本机代码时，例如System.EnterpriseServices.Wrapper.dll，您的选择变得更加有限。

您不能将 Windows DLL 与 MonoTouch 一起使用 - 它不是针对 iOS 架构编译的。您必须有一个专门为 MonoTouch 编译的 DLL，或者如果您有源代码，您可以自己构建它。
