Question

我正在尝试使用Microsoft EWS托管API构建iOS应用。我从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，它可以构建并运行良好，但在尝试定位物理设备时，mtouch会失败：

mtouch exited with code 1

我努力地补充道：

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，但当mtouch抱怨原生System.EnterpriseServices.Wrapper.dll时，我放弃了。

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

我也尝试了32位和64位版本的Microsoft.Exchange.WebServices.dll

P.S。我知道我可以在没有Managed EWS API的情况下使用EWS，但是编写和解析所有这些XML请求和响应是非常痛苦的。

Answer 1

MonoTouch的链接器和AOT编译器在完成工作时都需要存在所有依赖项。那个和缺少的符号（类型，方法......）使得从另一个版本的框架重用预先构建的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可以（没有丢失的符号）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），并且使用 JIT （无AOT）。这样就可以忽略缺失的引用/符号......直到它们（可能永远不需要）为止。

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你可以尝试来满足链接器，可以能够删除足够的代码让AOT编译器正常工作。遗憾的是，当事情归结为本机代码时，例如 System.EnterpriseServices.Wrapper.dll ，您的选项会变得更加有限。

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

是否可以使用Microsoft托管的EWS使用MonoTouch构建iPhone应用程序？
