UPDATE - 这确实仅在发布版本中失败，但仅在使用LLVM编译器选项时才会失败。为Xamarin创建一个独立的测试用例，我将作为答案发布。
我有一个使用ServiceStack.Common.Monotouch.dll，ServiceStack.Interfaces.Monotouch.dll和ServiceStack.Text.Monotouch.dll的项目。我可以在Simulator / Release＆amp; amp;调试和iPhone / Debug，但是当我在iPhone / Release中构建时，我收到以下错误：
...

如果有必要，我可以组合一个示例项目，但您需要的是Monotouch的最新ServiceStack dll或源代码以及ServiceClient的示例/设计DTO，以便重现这一点。
