Visual Studio 2017 为我的多平台 xamarin 应用报告此错误

Question

有人帮助我解决这个问题 4 天了，当我的应用程序开始报告此错误“此调试引擎不支持异常条件。条件将被忽略”时，它运行得非常好。它没有找到一些 dll.so 包，我尝试删除 bin 和 debug 文件夹，并重建应用程序，我还重新安装并安装了 Visual Studio，格式化我的 PC 并进行了全新安装，但均无济于事。当我尝试在 gitlab 的项目 Repo 中从不同的用户运行相同的应用程序时，也会出现同样的情况。我尝试了不同的模拟器，现在使用我的手机，但仍然是 mp 解决方案。

This debug engine does not support exception conditions. The condition(s) will be ignored.

Answer 1

在我的情况下，关闭 Visual Studio，删除 obj 和构建文件夹，然后再次构建后，问题就消失了。在 Visual Studio 中使用清理和重建选项不起作用，因此 Visual Studio 中的 Xamarin 似乎没有进行正确的清理/重建。

这是对时间的重大浪费，因为它从断点开始，只是在我不知道为什么的情况下没有按预期命中。消息This debug engine does not support exception conditions. The condition(s) will be ignored. 很容易错过，因为启动过程中日志中有很多噪音。
