使用Microsoft託管的EWS，可以使用MonoTouch構建iPhone應用程序嗎？

Question

我正在嘗試使用Microsoft EWS託管API來構建iOS應用程序。我已經從http://www.microsoft.com/download/en/details.aspx?id=13480下載了msi，並將該DLL複製到解決方案文件夾下。 建立用於模擬器，它建立並運行良好，但努力的目標物理設備時，mTouch觸摸失敗：

我努力補充說：

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

用的不是成長的感覺在正確的軌道上，但當mtouch抱怨本機System.EnterpriseServices.Wrapper.dll，我放棄了。

我試着玩項目選項/ iPhone生成SDK和鏈接器選項。

我也試過Microsoft.Exchange.WebServices.dll

的32位和64位版本

附：我知道我可以在不使用託管EWS API的情況下使用EWS，但編寫和解析所有這些XML請求和響應非常痛苦。

MonoTouch的鏈接器和AOT編譯器在工作時都需要所有的依賴關係。那些缺少的符號（類型，方法...）使得從另一個版本的框架中重用預構建的二進制文件變得困難（但並非完全不可能）。

它也解釋了爲什麼有時候（不會丟失符號）在模擬器上工作。默認情況下，模擬器版本設置爲「不要鏈接」（無鏈接器）和JIT（不使用AOT）。這可以讓遺漏的引用/符號不被注意到......直到它們（可能從未）被需要。

您可以關閉設備構建的鏈接器 - 但這對AOT編譯器不起作用。 OTOH你可以嘗試以滿足鏈接器，它可以可能能夠刪除足夠的代碼，讓AOT編譯器正常工作。遺憾的是，當事情歸結爲本地代碼時，如System.EnterpriseServices.Wrapper.dll，您的選擇變得更加有限。

您不能在MonoTouch上使用Windows DLL--它不是爲iOS架構編譯的。你必須有一個專門爲MonoTouch編譯的DLL，或者如果你有源代碼，你可以自己構建它。
