If you need to create an ASP.NET Core application, follow this, A valid Application Insights connection string. By default, when you use the automated experience from the Visual Studio template projects that support Add > Application Insights Telemetry, the ApplicationInsights.config file is created in the project root folder. The configuration file is named ApplicationInsights.config or ApplicationInsights.xml. (appInsights.Flush()). If the .config file references a nonexistent type or property, the SDK may silently fail to send any telemetry. Telemetry initializers may be called more than once. Tags only belong to current activity and does not flow to the child activities (internal or external). If you want to use standalone ILogger provider, use Microsoft.Extensions.Logging.ApplicationInsight. In the root directory of an ASP.NET application, create a new file called ApplicationInsights.config. The DeveloperModeWithDebuggerAttachedTelemetryModule class forces the Application Insights TelemetryChannel to send data immediately, one telemetry item at a time, when a debugger is attached to the application process. Telemetry Initializers are a powerful mechanism for customizing the telemetry that is collected by the Application Insights SDK. The Flush() method implemented by ServerTelemetryChannel isn't synchronous. If it's not created automatically, you'll need to create it yourself.
