Handle ASP.NET Core Exceptions Globally

Показать описание

Heyo! I'm Michael and in this video I’m going to talk about 3 ways to globally handle ASP.NET Core exceptions using the .UseExceptionHandler built-in middleware, writing custom middleware, and the new with .NET 8, IExceptionHandler interface. Plus a bonus on how to have multiple exception handlers.

Does your team handle ASP.NET Core exceptions globally or are you throwing try/catches everywhere? Got a horror story about weird exceptions? Let me know below. I love hearing these development war stories.

Greate video, really liking the new "watch as I code this" format. Seems more natural.

Thanks for the quick demo + explanation! Keep it up!

Great video. Love it. One way to mitigate the head issue is to have a github with the example code.

"Why is it magic? Because it just is." :D Love it!

Will this "global exceptions" work in.. Repository CRUD methods and in any network i/o C# code like file upload/download or any outside api calls.. ???

What it you use mvc and web api in the same project

Great video, only thing I don't like, architecturally, is the status code in the exception. The data or business layers shouldn't be bound to run in a http context. The status code should be determined in the exception handler according to the exception (base class, extending an interface, properties or whatever fits best)

taconaut

This doesnt feel right. Why does your service throw exceptions tied to http status codes when your service might not be exposed via HTTP?
What if I throw my service into an azure function or desktop application. It doesnt make sense to tie a network application layer into your code. This is why we have model validation before any user service is hit so we can separate out 4xx bad user requests and 5xx application errors.

I don't think user input should cause exceptions should they? If it does I'd let them to surface so you can fix them.

svorskemattias

I like it, but why return an exception when we know that it is an exception, it is better to return by result

anonim

Great job! But you are too big in the video. Can you make yourself smaller?

Your head is unnecessary man. I do prefer the only code video
Thanks for the video tho. Keep it ip
