{
var telemetryClient = new TelemetryClient();
telemetryClient.InstrumentationKey = "abc";
telemetryClient.Context.Session.Id = Guid.NewGuid().ToString();
telemetryClient.Context.User.AccountId = "Ben";
telemetryClient.Context.Component.Version = "1.0";
telemetryClient.TrackEvent("Application Start");

Answer 1

Possibly not an answer but will help those who search for this stack trace and don't read the comments on the question.
The OPs question was resolved when they checked the Instrumentation Key.
The stack trace is generated by vshub.exe when it attempts to read the files at C:\Users\bklooste\AppData\Local\Microsoft\ApplicationInsights\vstelAIF-312cbd79‌​-9dbb-4c48-a7da-3cc2a931cb70 to send in the offline telemetry.
This offline telemetry is provided by the Application Insights Persisted HTTP package. Without knowing the actual contents of the file it seems likely there is some corruption in the file. The file should look something like the snippet below. If for some reason the file was truncated or the URI is actually malformed then this exception will be thrown.
You either need to correct the URI, or (preferrably) just delete the file.
