ios - 启动 Xamarin iOS 应用程序失败并显示日志消息 "An error occurred searching types for the given assembly"

标签 ios xamarin xamarin.forms

总结

我尝试在 Visual Studio 中基于 Xamarin Forms 开发一个 iOS 应用程序，但我发现当我尝试运行该应用程序时，它无法在我的手机上启动。我有一个有效的 iOS 开发证书，并且我过去能够启动该应用程序，尽管我不确定从那时到现在可能发生了什么变化(我一直在断断续续地研究它)。

我在 Visual Studio 的调试控制台中遇到的错误是 Launch failed. The app '<<app name>>' could not be launched on '<<my iPhone>>'. Please check the logs for more details.

我进一步包含了 Xamarin 日志。

环境

我正在 Windows 10 PC 上的 Visual Studio 中开发我的项目。我在与 Xamarin Mac 代理相同的网络上使用 MacBook Pro，它通过 USB 连接到作为构建目标的 iPhone 6s Plus。

  • Windows 10 64 位
  • Visual Studio 2015 更新 3
  • Xamarin 4.1.1.3
  • Xamarin.Android 6.1.1.1
  • Xamarin.iOS 9.8.1.4
  • 装有 OS X El Capitan 10.11.6 作为 Xamarin Mac 代理的 Macbook Pro
  • XCode 7.3.1(在 Mac 代理上)
  • Mac 代理上的 Xamarin Studio 6.0.2(稳定 channel 无需更新)
  • iPhone 6s Plus(设备目标)

当我尝试执行我的应用程序时，我收到以下错误日志。根本原因似乎是它找不到 C# 类型 System.ComponentModel.Win32Exception :

更新

基于Marcos' response升级到Xamarin 4.1.2.18后我发现我仍然无法调试我的应用程序，但我得到了不同的错误日志输出，已发布 here (因为我无法将其放入此帖子正文中)。

它仍然提示找不到 Win32Exception , 然而。

更新 2

我可以在 Xamarin Studio 中构建和启动在我的 Macbook Pro 上开发的 Xamarin iOS 应用

我可以使用 Windows 机器上的 iOS 模拟器成功启动和调试我的(实际)Xamarin Forms 应用程序(如果我无法解决此错误，这实际上非常有用)。

我无法从我的 Windows 机器上在我的实际 iPhone 上成功启动/调试我的实际 Xamarin Forms 应用。

最佳答案

尝试更新到最新的 alpha 版本是 4.2.0.413 - 安装在 Windows 机器和 Xamarin Mac 主机上

关于ios - 启动 Xamarin iOS 应用程序失败并显示日志消息 "An error occurred searching types for the given assembly"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38818617/
