The TelemetryClient object exposes a set of Track methods that represents all of the core telemetry item types Application Insights understands. As soon as you instantiate a new TelemetryClient object, you should be able to send most telemetry through single method calls.
Joshua Weber, Microsoft has examines the concept of TelemetryClient with the help of source code in the official blog post.
The latest release of Application Insights SDK includes an enhanced trace collection to match the schema and processing of the other telemetry types. It ensures that all types are consistently handled in the UI to enable a common experience across all your telemetry data.
