Handling a specific exception in MVC Core 2.1

[kinetiq]

I'm hoping you can point me in the right direction... There's a certain exception that occurs in my project, and when it happens, I want to show a special error message to advise the user. My research has led me here.

Couple quick questions:

• Is this a reasonable use of GlobalExceptionHandlerDotNet? It seems a little more focused on WebAPI. I don't want to do anything that interferes with AppInsights/New Relic exception logging, etc.
• If I have come to the right place, could you point me towards some documentation showing how to do this? Most of what I see seems to be around generating text responses in WebAPI. Granted, there is a lot I don't know about this part of the framework .

In case you want more background... In my project, I'm using a 3rd party auth provider, Auth0, and I'm using their hosted login page. If a user ever goes to a stale login page (> 15m old), we end up with a Correlation Failed error, and one way to handle it may be with global exception handling. But I'm concerned this is all wild overkill, of course.

Thanks for your time!

Yes, this is correct. GlobalExceptionHandler at this moment in time is tailored towards WebAPI so is not capable of redirecting to a different route if an exception is handled. I've considered making an MVC version that would reroute based on exceptions but at the at the moment this can't be done.

Thanks for the info :) I think that would be a great use case, for what it's worth.
