Exception Handling in ASP.NET Core – Middleware vs Filters – What's Best?

When it comes to global exception handling in ASP.NET Core we have two major options: we either use an exception handling middleware or an exception filter. But what's the best way to go? As almost always in programming, it depends. The most important thing is to understand how these approaches are different and take informed decisions. In this video I provide a theoretical and practical comparison between these two approaches. But, in the end, the decision is yours.

throwing exceptions has never been so much fun, thx))
Great video, very clear explanation and good comparison!

What a wonderful video, thank you so much for taking the time to put it together. It was clear and well explained, one of the best I've seen, and I've seen a lot. Well done again. I appreciate your work. It's the first video of yours I've seen and I've already subscribed. I'm really looking forward to watching more of then. You mentioned that you could make a video going into some more of the concepts you covered. I'd appreciate that very much when you have the time. All the best!

Dude, great video, very nice simple breakdown. I came across the concept when I used to work in Spring/Java and was delighted to find out .NET has a comparable feature. Very well presented, I feel like I have a base-level working understanding of the implementation now, as I go return to the documentation. You've got my sub!

The way you explain, it helps a lot for a beginner like me. PLEASE MAKE ONE VIDEO DEDICATED TO EXCEPTION HANDLING MIDDLEWARE. 🙏 THANK YOU SO MUCH.

[EniloracCodes]

Thank you for this video. Very nice explanation and you always teach me something new!

[shahzadahmad-vgou]

Very informative video, Thanks a lot.

[samsonmayeem]

The encircling style of applying them is the most interesting thing after implementation

[itssalmanvlogs_]

One of the best explanations, Thank you

[karthikeyankanan]

I watched your video and learned petty good. I would you like you to create common response class for all the request in project. If possible plz post that video. Thanks

[victormoreno]

Great video, you know a lot! You pick my interest when mentioning the different exception strategies in layer. Also, I added the "filter exception" portion (based on what you explained) to my project, so am I missing something else, or this is it? Thank you for the videos, I am learning a lot from you.

Thank you so much for sharing this video. I always want to know what's the different between exception filter and exception middleware before watching this video, In short, We can only access Httpcontext in exception middleware directly, But in exception filter, Microsoft writes a lot of methods in ExceptionContext, We can more easily to use these methods to achieve what we want in our project.

Great video, very well explained. Subscribing for more thanks 🙏

[mihuntr]

Thank you very much for this explanation. Great video

[erivalo]

Go for the exception handling video pls.. or there is already one...?

[galdakaMusic]

Hi!! Great video. How can I access to user name claims un Middleware opción? Thanks un advance.

[lxocssx]

Thanks for this really helpful video. Would it be possible to use both to benefit from both their capabilities?

[mocococo]

Greetings from Bulgaria. Great tutorial and work. Thank you,
Please consider my question. On your schematic - should we understand that when using middleware then the request turns around and never continues to the rest of the blocks, like Controls creation, Auth. filters, etc.
Thank you.

Hi! Did you create the video about exceptions handler by using middleware?

[fonskeee]

what about the use of IExceptionHandlerFeature in the middleware ?

[karthikbalasubramanya]

Exception Middleware came later before exception filters exists... As u have concluded that exception filters is best to use compared to middleware..is there any specific reason when it is suitable to use Middleware than filters??
