How can I attach the login information(only E-mail ID) in the crash logs for my UWP application on HockeyApp. I wish to do this so that I can associate the user information of the testers of my application.
The HockyApp SDK has a user info API. You could use user info API to associate a crash with user email to further contain a user to get more details about the crash.
HockeyClient.Current.UpdateContactInfo("user_id","contact_info")
