The way to enable Application Insights for your ASP.NET Core application is to install the Nuget package into your .csproj, file as shown below. JavaScript only has telemetry initializers which can filter out events by using ITelemetryInitializer, More info about Internet Explorer and Microsoft Edge, Telemetry initializers add or modify properties, filter out events by using ITelemetryInitializer. To set the key for all instances of TelemetryClient, including standard telemetry modules, do this step in an initialization method, such as global.aspx.cs in an ASP.NET service: If you want to send a specific set of events to a different resource, you can set the key for a specific telemetry client: To get a new key, create a new resource in the Application Insights portal.
