我有一个引发异常的 C# azure 函数：

[FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            throw new Exception("Helpful message");
        }

异常被运行时捕获并重新抛出。在应用程序洞察中，这与消息Exception while executing function: Function1和调用堆栈一起记录。我无法在任何地方找到“有用的消息”。

在 Application Insights 中，我看到了这一点，并且没有一个属性具有“有用消息”文本：

调用堆栈显示错误的位置：

我有一个使用应用程序洞察的 Windows 控制台应用程序。我使用Microsoft.Extensions.DependencyInjection来设置我的课程并添加ILogger.

如果出现异常，我想将此记录到 Application Insights。但是由于 Application Insights 不会立即发送跟踪，我想刷新日志。

有没有办法触发应用程序洞察的刷新ILogger？

        static async Task Main(string[] args)
        {
            ServiceProvider serviceProvider = ConfigureServices();

            var program = serviceProvider.GetService<Program>();
            await program.Run();
        }

        public Program(ILogger<Program> logger)
        {
            this.logger = logger;
        }

        private static ServiceProvider ConfigureServices()
        {
            var services = new ServiceCollection();
            services
                .AddLogging(opt =>
                {
                    opt.AddConsole();
                    opt.AddApplicationInsights();
                })
                .AddTransient<Program>()
            return services.BuildServiceProvider();
        }

        public async Task Run()
        { 
            try
            {
                do.stuff()
            }
            catch (Exception e)
            {
                logger.LogError(e, "Exception occured");
                // How …
