     I develop a website with visual studio on win 10 OS 

     there is a feature used the FirstChanceException 

     at first request, the code and the page run very well

    then I close the page and open again, there are two first chance exception notification,  and then I wrap all the code on the request path with try-catch, there is no exception in my code and there is no error or warning win application event in the win log.

    could you give me more suggestion(s)? thank you.

    Hello,

    This forum is for development issues when using Excel Object Model. According to your description, your issue about exception in web application is off topic. I would move this thread into Off Topic forum and I suggest you post on https://forums.asp.net/ for issues when developing web applications. 

    Besides, you may visit https://blogs.msdn.microsoft.com/davidklinems/2005/07/12/what-is-a-first-chance-exception/ about the exception.

    Regards,
