ASP.NET Core MVC 2022 - 7. Dependency Injection + Repository Pattern

[@kylecollie7813]

Nice analogy with the restaurant buzzer for async. Good job!

[@TeddySmithDev]

Sweet thanks Kyle

[@theroostingroaster1584]

Man these tutorials are amazing, can't thank you enough Teddy.

[@codegate615]

I appreciated the refactoring lesson for DI/Repository pattern. Sometimes you skip over certain items without ever even briefly mentioning them such as why we use Scoped. Perhaps you'll go into it later, but I don't know that yet.

[@datguy4104]

AddScoped is an injection that's created only for that instance where it's called/injected and is garbage collected when it's no longer in use. The other option is singleton which is one instance used for all calls/injections.

[@huynguyenluonggia6393]

there are three types of dependency lifetime: transient, scope, and singleton. Transient for each handle, scoped for each HTTP request and singleton for all lifetime of application.

Thank you for what I'm learning from this series... I must complete this project. watching from Nigeria

[@jftechdrones]

Thanks for the tutorials, have been very helpful so far! Died a little inside at 16:30 though lmao

[@bjornhellgate3985]

This has been a really good tutorial so far, but why does some of the Club description say "This is the description of the first cinema" instead of club? are we secretly making a cinema page?

[@JFresh1977]

Really enjoying this series. Can't wait for the next video! :)

[@alzearafat]

Thank you so much, really helpful for beginners like me

This simply should be liked for how you laugh on copy-paste programming temptation at 19:25

Teddy, i my opinion, the MVC architecture reveals all the migty of interfaces. It often seems that there is no need in them untill you come acros this kind of projects... You define inteface, like You did here, then implement mock class for debug reson, then implement real data-oriented class and finaly, in one short string of code like "servies.AddTransient()", changing only one word (implementation) You change the whole behavior of your project! Isn't it amazin?! And thank You for yout series once more!

[@TeddySmithDev]

I wish interfaces were used more outside C#/Java because the power is insane. The most amazing part of programming is that we get paid 100K to do the job when it is so fun and easy lol

[@MyAutist]

@@TeddySmithDev No shit, bro! )))

[@BenjaminBrienen]

@@TeddySmithDev Sometimes interfaces are just called something else, like in Rust they are called "traits".

[@kvelez]

great use of async await

[@hachiq2154]

Thanks for that) I wanna ask what is the point to make actions Task? Why don't just leave them IActionResult

[@TeddySmithDev]

Task makes it async. Async basically means more speed because it can run more then once chunk of code at a time.

[@hachiq2154]

@@TeddySmithDev oh, thx, got it

[@1Eagler]

06:00 I prefer returning a tuple T

[@TeddySmithDev]

You could return an object you created and populate with your own data. Tuple works great too. Go with your instinct!

[@abdumannonnorboyev4025]

thank you for lesson

[@1Eagler]

Why having one file per interface? I prefer having them in one file so a) I have one file open and b) I can find easily with the dropdown. Same with classes.

[@TheAndyCooperz]

What's your opinion on separating your project into multiple solutions e.g. Hosting, Core and Persistence? Also, you copied all the code from one interface to another, what is your opinion on having a base interface with definitions that are shared amongst many repositories then in your repository interfaces having definitions that are specific to each repository? Great videos by the way :)

[@TeddySmithDev]

I'm not really a fan of multiple solutions (personal choice), but for huge projects it's a must i think. Base interfaces can be great actually. People call them a design flaw but they work well when you are just using regular CRUD. Thanks for the comment!

[@kishorl7190]

Can you tell me why we need this pattern , it's so confusing

[@huynguyenluonggia6393]

hello everyone, for this project, I want to add a folder named Service can I add services that I use?

[@siemkagospodarzu967]

Can you explain why the hell are you creating interfaces instead of just putting these methods to these repository classes? Interface is useful when you use it in multiple classes.

[@TeddySmithDev]

You’re right but no using an interface would cause down votes and people to leave. Not using interface on class is not “cool” lol

[@boky7731]

Because he is trying to teach the pattern that is widely used in the industry, on this example that is perfect for that

[@siemkagospodarzu967]

@@boky7731 So you are wrong because this is not good example to use interface. And I say this as someone who has been working in this industry for several years.

[@xavrock1112]

Hi. In 10:13 Why didn't you use SaveChanges ?

[@huynguyenluonggia6393]

you can use it directly in other methods or follow him

[@tlhsieh4803]

Good video. Could I know the difference between "_context.Add(club);" and "_context.Club.Add(club);" ?

[@huynguyenluonggia6393]

so different, _context is an instance of class ApplicationDBContext. This class has a property named Clubs, which is a table in the relational database. So command _context. Clubs to access table Clubs in database and _context.Add() is wrong

[@codegate615]

Why did we make the Get code in the Interfaces Task?

[@TeddySmithDev]

Watch my interface video

[@mohamedal-qadeery6530]

@@TeddySmithDev why we didn't add Task in crud methods Add,update,delete,save ?

[@nederlandshiphop]

@@mohamedal-qadeery6530 probably because its not async funtion :)

Hello can you make a video on jwt auth with refresh jwt token and roles in web api?

[@TeddySmithDev]

Im busy with MVC right now but I'll get around to it.

[@hackerw2]

your video was super helpful just a small criticism and I am saying this in the most friendly way possible so please don't take this personally just work a little more on your typing because you typed the wrong characters way too much I think the main reason is you look at your keyboard when you type which will result in you not knowing if you are typing wrong or not and will result in distraction from the main topic Thank you again for the time you took to make this video

[@TeddySmithDev]

Zero offense taken lol. This is something I will look into.

[@wesamhuseein7952]

your videos are to long

[@TeddySmithDev]

many people suggested to shorten videos so I keep them 10 mins now 👌
