I have a .net core 3.1 web application, specifically it is an identity server 4 app which i use to get token for other client apps. Now consider the app was running correctly and also producing tokens for clients but suddenly it terminated without any exception and this is happening many times.

Identity server 4 events logging is available in output window while running identity server. Please check events log in output window and try to see what is going on. Moreover you can share log.

  • you will log like above comments and you can see all are info log and when you will get error then error will be marked – Always_a_learner May 04 '20 at 10:53
  • ok so you are taking about logs. I am logging all the logs into log file but when application terminates and i check logs i see that there is no err logged into logs file. And also if there any exception occurs visual studio shows the exception but not in my case, i think it is not any exception which causes the application to terminate it is some other problem which i don't know – M Waleed Raza May 04 '20 at 11:15
  • is your problem encountered in production or development environment(visual studio)? – Always_a_learner May 04 '20 at 11:18
  • both in production and in development environment. In production i face the problem server has been shutdown or service is unavailable several time and in development(visual studio) i see that application terminates without any exception – M Waleed Raza May 04 '20 at 11:44
