在解决方案的主要项目中,我有:
public static void Main(string[] args)
{
// Testing Logs on Azure Application Insights:
var telemetry = new Microsoft.ApplicationInsights.TelemetryClient();
telemetry.TrackTrace("Test of ApplicationInsights.TelemetryClient() on Program.cs");
CreateWebHostBuilder(args).Build().Run();
}

它正在工作,并且日志正在Azure应用程序见解中显示。
不幸的是,当我将相同的代码添加到相同解决方案的另一个项目中时,它不起作用:而是在Azure上引发异常。
我尝试添加对主项目的引用(因为我认为这将导入其项目和其他所需的内容)。不幸的是我不能,因为它说:
不允许循环依赖
因此,我在解决方案的其他项目中添加了相同的细节。这样,它便可以编译,并且我可以上传到Azure。但是由于该错误,我看不到日志(跟踪):
在Azure上显示的日志的文本版本(Trace):

我使用的是Visual Studio for Mac(又名VS for mac 2019)。注意,它实际上与Windows的Visual Studio不同:使用Windows的Visual Studio在Azure上调试要容易得多!
我究竟做错了什么?
尝试通过 nuget 包管理器或 dotnet cli 命令将包添加到项目中
dotnet add package Microsoft.ApplicationInsights --version 2.10.0
