Xamarin Profiler 无法连接和来自 VS2015 的运行 iOS 应用程序

Question

我正在尝试分析 iOS 应用程序以诊断内存泄漏。当我尝试从 Visual Studio 运行 Xamarin Profiler 时，应用程序可以编译并部署到设备上，但是在加载 Profiler 并且我 select 监视哪些位时它会暂停然后报告 "Sorry, something went wrong trying to run ***"。日志输出如下：

我正在运行使用完全更新的企业版 Visual Studio 2015 U3 和 Windows 8.1 上的最新稳定 Xamarin 工具，以及 Xamarin Studio 上的最新稳定工具MacBook Pro 运行ning OSX 10.11.5，以及最新的 Xamarin Profiler。我的测试设备是 iPhone 6 Plus 运行ning iOS 9.3.2。设置正常运行良好，完全调试等，没有问题。

欢迎任何帮助！

目前这是一个已知问题。我们确实有一个错误报告，但它是内部的，所以很遗憾我不能分享任何细节。

我建议现在直接在您的 Mac 上试用 Profiler - 或者使用 Instruments:
