Event Viewer allows us to monitor events in window system. It maintains logs about program, security, and system events on computer. To access Device Manager, on the Start menu, click Programs, point to Administrative Tools, and then click Event Viewer.(window log>application)

Herry, as eailer I have answered, final block should be execute everytime. It is not depended on ctrl+f5 or f5. But I think you are facing this issue is something related to visual studio debugger. To analyze actual cause, Need to look into event viewer, CLR versions etc. So, it is question of the analysis further. I will surely try to generate from my side. Hope it is helpful for you.

I am using visual studio 2017

--->finally block is executed when there is no run time error...
--->I am able to execute finally block while using cmd prompt
--->Finally block is also executed when i am using cntr+F5 when i m giving wrong input.

I am not able to execute finally block whe i am not using cntrl+F5 and when i am giving wrong input.

Hi Thank you...I have used console.ReadLine...but finally block is not executing...I have tried even in notepad....it is working in notepad...but not working in visual studio..

No, ctrl+f5 is used to run program without debuging and only f5 is used to run program with debugging in visual studio. Apart from that, Please add Console.ReadLine() after final block. so, you can check out final result in console. final block is used to execute a given set of statements, whether an exception is thrown or not thrown. Hope it will helpful for you.
