我正在尝试使用单声道分析器分析Xamarin.Mac应用程序，但遇到错误。该应用在本地构建，用于使用 Visual Studio for Mac 进行调试，并使用 MSBuild CLI 为 App Store 构建。
我试过这个：
-
通过 Visual Studio for Mac 构建应用，其中包含完整的调试信息
-
mono --profile=log "MyApp.app/Contents/MonoBundle/MyApp.exe"
失败了
标准输出：

如何解决此问题？更一般地说，如何使用单声道探查器分析 Xamarin.Mac 应用捆绑包？
相关问题：在 Xamarin.Mac 应用程序捆绑包上运行仪器，它询问如何使用 Mac 版仪器而不是单声道探查器进行分析。

MONO_ENV_OPTIONS
我尝试了菲利普·纳瓦拉的答案
Xamarin.Mac 具有特定的启动序列，并嵌入了特定版本的 Mono 运行时。通过直接运行"mono"，您可以绕过启动序列，这可能会导致问题。正确的方法是使用 MONO_ENV_OPTIONS 环境变量传递选项：MONO_ENV_OPTIONS=--profile=log MyApp.app/Contents/MacOS/MyApp。
但我收到一个错误：
echo $MONO_ENV_OPTIONS
MONO_ENV_OPTIONS=--profile=log /Users/chase/MyApp/MyAppWeb/projects/MyApp.Mac/bin/Debug/MyApp.app/Contents/MacOS/MyApp
cd /Users/chase/MyApp/MyAppWeb/projects/MyApp.Mac/bin/Debug/MyApp.app/Contents/MacOS/
./MyApp
Cannot open assembly '/Users/chase/MyApp/MyAppWeb/projects/MyApp.Mac/bin/Debug/MyApp.app/Contents/MacOS/MyApp': File does not contain a valid CIL image.
如果我清除MONO_ENV_OPTIONS，则不会收到错误，并且应用程序运行正常(但是，当然，探查器不会运行(。
我不确定它是否有助于解决您的特定错误，但这里有一些提示。

分析应用程序的另一种方法是调整 MonoDevelop 代码。它使用系统sample工具，然后对输出进行后处理，以将不透明的函数偏移量转换为 .NET 方法名称。
