Question

我正在尝试按照Insights Preview中的说明创建自定义遥测。我完全按照说明操作。但也许我的配置错了。

我在APPINSIGHTS_INSTRUMENTATIONKEY文件中设置了local.settings.json，似乎工作正常。但是当我添加一个新的TelemetryClient时，我开始得到那些重复的错误（下面）。它在调用函数时发生。

我真的希望来自AF的遥测数据转到相同的AI仪器键，所以我可以一起看。

我也将Microsoft.Extensions.Logging拉出来，因为我只想使用AI，如果这有任何区别的话。

有人有任何建议吗？

见下文......

TIA

我从一个新的自动对焦项目（和一杯葡萄酒）开始，以保持简单。

以下代码有效：

private static TelemetryConfiguration config = new TelemetryConfiguration { InstrumentationKey = System.Environment.GetEnvironmentVariable("APPINSIGHTS_INSTRUMENTATIONKEY", EnvironmentVariableTarget.Process)};
private static TelemetryClient telemetryClient = new TelemetryClient(config);

此代码（直接来自预览帖子）不会：

private static TelemetryClient telemetryClient = new TelemetryClient();
private static string key = TelemetryConfiguration.Active.InstrumentationKey = System.Environment.GetEnvironmentVariable("APPINSIGHTS_INSTRUMENTATIONKEY", EnvironmentVariableTarget.Process);

不幸的副作用是遥测不会自动显示在VS2017 Application Insights窗口中。您必须使用设置齿轮来选择所需的AI存储库，然后您才能看到它。几分钟后，但总比没有好。
