Is hosting app responsible for calling Flush() when ends?

[jiberan]

Hi,
my WCF service is hosted in windows service but I'm not sure if I need to call client.Flush() when windows service stops to ensure that all data will be send.

Should I call it manually?

Thank you.

The default telemetry channels do buffer data, so you indeed might want to call Flush() before terminating.

As good place to call Flush() looks OnStop() method in Windows service. But do you know how get instance of TelemetryClient in this place?

@jiberan You can just initialize one based on TelemetryConfiguration.Active, which will tie it to the configured telemetry channel, afaik.
