 If you want to store the connection string in ASP.NET Core user secrets or retrieve it from another configuration provider, you can use the overload with a `Microsoft.Extensions.Configuration.IConfiguration` parameter. For example, `services.AddApplicationInsightsTelemetry(Configuration);`.
 In Microsoft.ApplicationInsights.AspNetCore version [2.15.0](https://www.nuget.org/packages/Microsoft.ApplicationInsights.AspNetCore) and later, calling `services.AddApplicationInsightsTelemetry()` automatically reads the connection string from `Microsoft.Extensions.Configuration.IConfiguration` of the application. There's no need to explicitly provide the `IConfiguration`.
 
+If `IConfiguration` has loaded configuration from multiple providers, then `services.AddApplicationInsightsTelemetry` prioritizes configuration from `appsettings.json`, irrespective of the order in which providers are added. Use the `services.AddApplicationInsightsTelemetry(IConfiguration)` method to read configuration from IConfiguration without this preferential treatment for `appsettings.json`.
