[@Netherlands031]

I really like that you show us the framework source code, and start from a very simple program to build it up, but for me the explanations were too concise, I had to rewatch some parts several times and still I feel like I understand it 50%. For example the two ways of activating middleware at 15:20 - one gets passed the db context when invoked, one doesn't?

[@RahulNath]

Thank you for your feedback and I will try and elaborate on the topics. Some of my recent videos are less dense I guess, but will be happy to get your comments too. As for the dbContext, yes that is correct. The Convention based pattern does not use Constructor Injection, whereas the Factory based pattern does. you can read more about it here if that helps docs.microsoft.com/en-us/aspnet/core/fundamentals/middleware/extensibility?view=aspnetcore-5.0&WT.mc_id=AZ-MVP-5003875.

[@deivamanidhandabani9505]

Hi Rahul, Hope you are doing great! I'm continuously watching your technical videos. I had doubted for a very long time could you please explain. Let's say, by using HttpPost verb for saving resources/details in the database and we use HttpPut for updating, HttpGet for getting the details from the database, HttpPost to save data in the database and HttpDelete for Deleting a record from the database. But why we should use different verb for like Get- HttpGet Save - HttpPost Update - HttpPut Delete - HttpDelete Could you please explain and Thanks in advance. Thanks, Deivamani

[@RahulNath]

Yes you can achieve the same with one header verb (any of them) but it's more about following a standard. This makes it easy to work with APIs and is in line with the HTTP standards. Anyone consuming your APIs within your team/external/new member would all know this convention by default and not something that needs relearning. Read about Richardson Maturity Model here martinfowler.com/articles/richardsonMaturityModel.html. It explains it a bit further. Hope that helps.

But I think the presentation must be a bit more engaging Rahul, having ups and down in your tone, a bit entertaining with some occasional smiles or funny comments may be. Otherwise I love your channel personally keep up the good job

Thank you Kiarash and happy you like the content. And I totally agree to you on the presentation side. I really need to work on that and have some plans in place. Hopefully soon I will get better at it. Thank you again for the valuable feedback and the support! 😀

I am trying to follow up with .NET 6 and the code is different. So far so good, but when I try to comment out part of the code to make it close to the content of the video it won't run. Basically there is an app.Map I commented to just pass this line: app.Run(async context => await context.Response.WriteAsync("Hello World!")); Now the application does not display but terminates instantly. I just tried to add another empty app.Run() and now it executes. Why is that? Why can't I simply put the line above and have a window display? I tried to duplicate the line above and it won't run neither. It seems that on .NET 6 you must finish with that empty Run() no matter what. Also not putting anything simply won't compile because without the beginning var builder = WebApplication.CreateBuilder(args); statement, the compiler finds no static Main(). Having just that line exits as before (return 0). Very interesting. I'm going to on now and edit this if needed.

Played with Use() Middleware Made 3 in a row and output it. This is the sequence. Before Request 1 Before Request 2 Before Request 3 After Request 3 After Request 2 After Request 1 All this sounds a bit like Matroskas which is how I got decorator pattern explained. But the idea of deciding if we send the request further looks like chain of responsibility pattern to me.

Hi Rahul, could you explain custom exception middleware and how to handle try catch block inside middleware???

[@RahulNath]

Thank you for the suggestion Nishanth and Sure will do. Meanwhile you can look at this post for an example ankitvijay.net/2021/04/21/consistent-error-handling/

[@nishanths3542]

Thank you Rahul

Amazing!

Thank you! Cheers! Glad you are enjoying the series bit.ly/asp-net-core-series

Hi Rahul, how the request delegate knows to call next piece of middleware in app.use extension method.

[@RahulNath]

The framework passes in the next middleware in line to the next parameter. This is based on the order they are registered in. Does that answer your question?

[@keeplearning1564]

@@RahulNath can you explain next delegate a little. I thought next delegate knows how to call next middleware. But it seems framework is doing it. Then next delegate is just to tell framework to call next piece of middleware?

_ @keeplearning As from the doc here docs.microsoft.com/en-us/aspnet/core/fundamentals/middleware/?view=aspnetcore-5.0&WT.mc_id=AZ-MVP-5003875 _Each middleware component in the request pipeline is responsible for invoking the next component in the pipeline or short-circuiting the pipeline_ Does that help?
