无法跟踪ApplicationInsights

Question

我已经创建了一个新的Azure Web作业，一个新的Application Insights资源，我只是想让一个人登录到另一个。据我所知，它应该像添加适当的NuGet包一样简单，并在这些行中添加一些代码：

TelemetryClient tc = new TelemetryClient();
tc.InstrumentationKey = "my-key";
tc.TrackEvent("testing");
tc.TrackTrace("test diag");
tc.Flush();
System.Threading.Thread.Sleep(1000);

睡眠是因为我找到了this MS文章，表明可能需要它。此代码发生在Web作业启动时（如此有效，它只是一个控制台应用程序）。但是，当我运行它时，我没有任何指标。

我已经尝试将密钥放在ApplicationInsights.config中，但这没有任何区别。我也尝试过不同类型的日志记录，包括异常。

我的猜测是上面的代码没有按照我的想法行事，但如果有人能指出我正确的方向，我将不胜感激。

我可以通过在Azure Webjobs功能代码中插入TrackEvent调用来track user events，以下示例在我这方面工作得很好，你可以参考它。
