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.

At the start of the videos you can show the Agenda, explanation of the concepts and at the last you can summarizes what are all the steps required or done to implement the logic.. Can you also provide a Video on Serilog,intergrate Serilog with AWS elastic search and Kibana.

This is something I was looking for my project. Handling error from a centralised system will surely save a alot of development efforts. Just had one doubt Why did you make your domain exception class as abstract ? What if, we don't make it abstract?

@RahulNath 3 года назад

Thank you Bhavya. It's optional to mark it as abstract. (22:25) Only if you want to make sure across the code base you want more specific exceptions to be created instead of using the base class always. Hope that helps.

Certain Exceptions need additionally a code mining strategy and we can use the ctor/BaseTrace (Assembly.GetCallingAssembly().Getname().Name ) added to the middleware to deliver a multilevel ring trace on a circular queue available on production mode, to locate the path of code.

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 3 года назад

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

@RahulNath Год назад

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

@DjHomerr Год назад

@@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.

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YR6HkvNBpX4.html And other videos in this series bit.ly/asp-net-core-series

Hi i have created an asp.net core web api and added custome middleware but its still throwing the exception before going to middleware catch block..do wee need exception filter to handle that?

@RahulNath 2 года назад

Yes I think so - hope you were able to catch that?

Is it possible to pass multiple parameters to "DomainNotFoundException" class and access those parameters in ExceptionHandlingMiddleware class ?

@RahulNath 3 года назад

Sure. Any number of parameters and types as you wish. it’s a custom type, so you can control it. let me know if you are running into any issues

@Blr046 3 года назад

@@RahulNath Yes, I am able to pass the arguments, but I don't know how access those parameters in global ExceptionHandlingMiddleware class. I want to print the exception in the log in common place.

@AbhinavSingh-ov7pj 2 года назад

This is good but model validation error are not caught in above solution. Just need code where we can caught exception and Model validation at same place so that api can return common response.

It was a lot easier with the previous .NET v4.x; We could do this out of the box : 1) return Request.CreateErrorResponse(HttpStatusCode.NotFound, message); 2) throw new HttpResponseException( Request.CreateErrorResponse( HttpStatusCode.NotFound, message) ); Can anyone show an example where the http Client Library (e.g. axios, fetch) can actually capture the status-code, and custom message thrown by the web-api DOT NET CORE BULLSHIT?

Indians start explaining anything by first creating a project. You all.shall.see one more time how to create a project. And name it "my project".

@RahulNath 2 года назад

Not sure about all "Indians" Emre, I do that to start from familiar grounds to someone new to a concept. This helps teach more easily than starting from a big code base. Not sure if you watched past the project creation and had any suggestions on that. Thank you!

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.

@RahulNath 2 года назад

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.
