【中文标题】如何使用 WCF 中多个环境的检测密钥配置 Application Insights？【英文标题】：How to configure Application Insights with instrumentation keys from multiple environments in WCF? 【发布时间】：2021-06-08 21:40:32 【问题描述】：如果我使用this Microsoft documentation 中所述的ApplicationInsights.config 文件设置我的 WCF 项目，并且数据按预期记录到 Application Insights（使用硬编码的检测密钥）。
在使用 ApplicationInsights.config 文件时，是否有任何方法可以基于每个环境指定检测密钥？
配置文件如下所示：

This documentation 建议我可以在代码中设置检测密钥（例如在this answer 建议的AppInitialize 方法中），但它似乎不起作用。
TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
configuration.InstrumentationKey = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
【问题讨论】：
【参考方案1】：虽然此解决方案似乎有一些注意事项（取决于您的托管策略），但有时可以添加 Global.asax，并使用 Application_Start 挂钩来注入您的配置（此答案假设您是使用配置转换）。
例如：
using System;
namespace SomeWcfThing
public class Global : System.Web.HttpApplication
protected void Application_Start(object sender, EventArgs e)
Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration.Active.InstrumentationKey =
System.Configuration.ConfigurationManager.AppSettings["InstrumentationKey"];
【讨论】：
【参考方案2】：正确的方法是使用 TelemetryConfiguration.CreateDefault() 方法从磁盘加载任何配置，然后在生成的配置上设置/更改其他值。
创建 TelemetryConfiguration 实例后，将其传递给 TelemetryClient 的构造函数以创建客户端并开始记录。
