ERROR HANDLING In ASP NET Core | Getting Started With ASP.NET Core Series

Hey Friends,
Exception handling or error handling is an important aspect of building applications. However much we want our applications to work fine, there will always be some unexpected cases. It's important that we handle these scenarios and return back appropriate messages. This is no different when building our APIs.
In this video, I will show you about exception handling in ASP NET Core Applications and the different ways we can handle them. I will also show you how to set up global error handling and the required middleware for that. Based on the feedback I received, I will also be showing some real-world examples of using Exception handling.

I love Command line since I used to be trained sysnet admin. Today as a developer on a VM I face terrible slowdowns with graphical tools. On a CLI I do the action in no time. I was not given a VS license for a while and I had to deal with .NET CLI. This is nice to know those options too. It may sound foolish but sometimes using dotnet CLI unlocked strange situations compiling through VS did not help. Less often it can be the other way around. Anyway I am here to learn about that error handling stuff. I just learnt there is a way to globally handle exceptions and that can be handy for a task I am given to setup logging. EDIT: After having watched the video it is not talking about what I heard about but that is very interesting.

How do you implement this in an Azure function since the azure function has some work around? Can you explain ?thanks.

[@RahulNath]

With Azure Function since the code is more isolated I would handle it within the function handler code. if there are a lot of functions, I might add a base class to handle API calls and implement common handling there.

Thanks for the video. I have a question. What if I have multiple ExceptionHandlingDomains? (maybe I have a few different projects to handle different areas of the business in my app) How my ExceptionHandlingMiddleware is aware of what ExceptionHandlingDomain to use?

[@RahulNath]

Might need more details. But the handler can be extended to switch case on any Exception Type. Check this gist (from a friend of mine) gist.github.com/ankitvijay/168c41f3abb3e817375be05e7b2e7083#file-2_exceptionhandler-cs for an example Is that what you were looking for? What issues are you particularly facing?

[@callegarip]

@@RahulNath I am not running into issues yet b I just started implementing error handling and I watched your video and I’d like to implement it. So let me give you more details. I have a multi layer project. I called ManagerXXX to a project that handle certains things in the app. I think you called it Domain project. You could also think my ManagerXXX like my services. So I want to create a custom ManagerXXXHandlingException for each of those projects I have. My question was how can I make my ExceptionHandlerMidleware to be smart to decide what type of exception to use. I know that if I just keep adding CATCH CATCH CATCH… for all the ones I have on each manager will work, but that seems to be odd. I was wondering if there is a pattern for this scenario.

Hi Bro. Thanks for this video. I have one doubt. Can we simply use throw new exception kinds inside the code ? Is that a proper way?

[@RahulNath]

Sure you can - but it becomes limiting. Having specific or categorized domain exceptions allows you to capture and handle for it at central handlers. This makes it more powerful. Also when you look at logs you can immediately filter out based on the type of exception. So my preference is generally to create specific exceptions, but nothing stopping you from doing new Exception("Message"). Hope that helps

Hello Rahul, could you explain why the lifetime of a Exception Handling Service is transient and not scoped?

[@RahulNath]

since there is no state to be managed in there. Any reason you are looking at why it needs to be scoped?

[@DjHomerr]

@@RahulNath No particular reason. I just couldn't understand why transient, and what does the lifetime of a exception handling service even mean? I have my web api with a couple of services that just deal with basic crud operations involving a database, and scoped lifetime seemed like a good choice for those. So i thought the exception handling middleware service would be the same.

[@RahulNath]

they make sense only if you need to keep context + state in the context of that scope. In this case it isn't required - Do check out my DI video kzbin.info/www/bejne/j4OZeZ6sg6ejjpY And other videos in this series bit.ly/asp-net-core-series

Awesome content, Thank you ! Can we have something like this in a method. Public int SaveEntity() { try { context.SaveChanges(); } catch(DbUpdateException exception) { throw new SomeDomainException(exception?.InnerException); } } and catch that "SomeDomainException" in middleware.

Yes, you could do that - nothing stopping you from doing that. It might soon be a lot of exceptions depending on the granularity of these classes.
