Global Exception Handling in Asp.Net Core Web API using IExceptionHandler

Global Exception Handling in Asp.Net Core Web API can be done using IExceptionHandler. The IExceptionHandler interface in asp.net core is a newly added concept and it is used to avoid try-catch from your asp.net core application by handling the exceptions globally.
The IExceptionHandler interface in dotnet core can be used to handle the exceptions globally in all the asp.net core frameworks like asp.net core web api, minimal apis, blazor, asp.net core mvc etc.

Very clear. Thanks Nitish

[@GurdeepSingh-cg1yp]

The use of "if not" in the exception handlers is not a good idea as that would mean you will need to add a new check to all your handlers every time you add a new exception handler.

[@geragamo]

nice

[@NaveenKumar-dc8jv]

Simple and good. :)

[@coding-gemini]

This is good stuff bro, thanks. What if we want to continue processing other code and not return back the exception to the controller just logging it, how do we do that.

[@UnbiasedThamizhan]

Your intention is right, but not clear; You have to stop and show the difference between two handlers.

[@farapar3783]

if my app can not to connect to db then how this handler can help because in my code i cant throw excetion

[@nitish.kaushik]

You don't have to throw the exception explicitly. I was throwing them just for the demo.
Otherwise this Handler will catch all the exceptions.

You can handle multiple or even all exception types in one single exception handler.
