Internet connection required for Diagnostics init?

Hi Telerik Team,

I'm tracking down some serious performance problems in one of my apps where very few users report that startup takes quite long, especially when there is bad internet connection. Even though I couldn't find any internet communication when listening using a network sniffer (Fiddler) I'm still not sure whether there is some random traffic or not.

While searching (again) through my code I stumbled upon RadDiagnostics that I use to get error reports. Everything works fine.

So my question is: When initializing RadDiagnostics using ApplicationUsageHelper.Init() or ApplicationUsageHelper.OnApplicationActivated, is there any internet traffic from time to time that is used to get some of the information from the error mails that are generated?

I guess the answer no, but I just wanted to look at all possibilities.

Regards, Stephan

Hello Stephan,

Thank you for contacting us.

The ApplicationUsageHelper.Init() method generates application specific data (version, installation date, previous run date etc., you can check the ApplicationUsageHelper.ApplicationUsageDataModel class to see all generated data) and saves it to the isolated storage. The OnApplicationActivated() method reads the last saved application data. No internet traffic generated in these methods.

I hope this helps.
