Telemetry initializers always run before telemetry processors. If you need to do a synchronous flush, use InMemoryChannel. Additionally, as per the same documentation referenced before, " We don't recommend creating new TelemetryClient instances in an ASP.NET Core application ". The rest of this article assumes you are using version 2.7.1 or later of the Nuget package. Because of these retry mechanisms and local disk storage, this channel is considered more reliable. public class AppInsightsInitializer : ITelemetryInitializer { public void Initialize (ITelemetry telemetry) { var identity = WindowsIdentity.GetCurrent (); if (identity != null) { var name = new WindowsPrincipal (identity); telemetry.Context.User.AuthenticatedUserId = name.Identity.Name; } } } This works well on a localmachine.
