Xamarin.iOS生成中出错：不支持给定路径的格式

在Visual Studio 2015的一个iOS项目中，连接到Mac，我在构建时遇到了这个错误

C:\Program Files x86\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets411,3:错误：不支持给定路径的格式

相同的解决方案复制到Mac版本，并在Visual Studio for Mac preview中正常运行

第411行位置3处的Xamarin.iOS.Common.targets是：

<SmartCopy
    SessionId="$(BuildSessionId)"
    Condition="'$(IsMacEnabled)' == 'true'"
    SourceFiles = "@(_BundleResourceWithOutputPath)"
    DestinationFiles = "@(_BundleResourceWithOutputPath -> '%(OutputPath)')"
/>

---

有人能告诉我问题出在哪里吗？

该错误是由文件名程序文件x86中的空格引起的

解决方法是用正确的转义字符串替换空格

替换%20
