azure - 无法使简单的 AppInsights Hello World 工作

Question

考虑以下简单的程序:

Program.cs

using Microsoft.ApplicationInsights;

namespace azure
{
    class Program
    {
        static void Main(string[] args)
        {
            var tc = new TelemetryClient();
            tc.Context.InstrumentationKey = "***MY KEY IS HERE***";
            tc.TrackTrace("Hello World!");
            tc.Flush();
        }
    }
}

packages.config

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Microsoft.ApplicationInsights" version="2.5.1" targetFramework="net452" />
  <package id="System.Diagnostics.DiagnosticSource" version="4.4.0" targetFramework="net452" />
</packages>

应用程序配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
</configuration>

我在 Visual Studio 2015 中编译它。

它应该向我的 Application Insights 帐户发送一些内容，对吗？但我什么也没看到。

有什么想法缺少什么吗？

Answer 1

如果您对此进行调试，并在应用程序结束之前设置断点，您是否会在控制台中看到应用程序洞察的输出？

问题是可能在任何东西有时间启动出站http并实际发送您的数据之前您的进程就结束了。

flush 方法不是同步的，应用程序在终止之前不会等待它发送。
