Trying to understand dependency injection and having watched almost every tutorial on youtube about it this is one of the best (and relatively short!) - looking forward to more content and any videos covering examples of the different types of dependency injection maybe? (constructor, property etc)
As I understand there are different types of dependency injection - was just curious to see actual real examples of say constructor and property dependency injection and maybe some common use cases (the default .Net web api template in Visual Studio does show this but I find it a little confusing to follow)
This is the only video that made sense to me; I can properly understand all the docs that mention it now. I don't get why many tutorials make it so complicated and use different frameworks with many abstractions instead of explaining the basic concept. Your explanation, on the other hand, was clear and concise. Do you have any plans in making a rest web api in ASP NET following some architecture for scalability? Many of the videos I have seen are somewhat lacking and make use of a lot of dependencies and interfaces without ever really explaining what they do. Regardless though, thanks so much for the video!

Thank you, Gerald. I had an idea about D.I., and now, your explanation has confirmed I had It right and has given me a wider understanding of it. Keep the great job!
Gerald... thank you for explaining the way I explain... hitting the important points and the why. I'm sharing this with people I mentor in OOP development! Thanks for the great explanation.
This is really underrated content! I want to know more about DI and containers in Xamarin. Would be great if we could build something like Prism DI from scratch. This topic is harder to process than others, but it's really valuable, you can add more screenshots or illustrations, it will make it easier to understand. Good job and thanks for your effort!
Thank you so much! I’ll think about it. As mentioned in the video; there are a lot of good options already so you probably want to stick with one of those unless you have really good reasons not to. Nevertheless it’s always good to build something yourself to really understand the inner workings
I've started a small attempt at making a Prism-like IoC container. It's pretty basic right now. Please feel free to do what you want with it. I haven't updated it in a couple weeks. github.com/mdh09/MyFlyIoc
Have seen a lot of Videos on Dependency Injection, but this is like the GodFather of all. You videos have great clarity of concept. Keep doing such videos :)
Great video! I would benefit from looking at a project that is consuming DI. I would also like to see some practical comparison of the built in DI vs TinyIOC vs AutoFac.
I like it. But fortunately, if you don't, you can easily change your IHair interface implementation.. 😄 Thank you very much for beautiful thorough explanation of dependency injection concept...
You explain perfectly, a very simple and useful video, after it became clearer, thanks! And cool English, clear pronunciation, simple words, it's cool for foreigners like me)
Wow i finnaly understand it. Now i also understand why Dependency Injection is used in tests which are testing user input, its much smarter than force fake input to console using StringReader and Console.SetIn method. Thanks again!
Great Video.. Suggestion:: Just take an example(logger) and code along(using container, Interface) like you did for Messaging centre video. It would be easy for beginners like me to grasp easily by seeing the output. Thanks!!.
your explaination is really helpful, I just came across the "dependency injection" concept and have no idea what it is. But after what your video, I think I understand it a little bit. Thank you!
I got this asked in an interview, and even though I understand how it works because I currently use it in my job, I didn't know how to explain it. So thanks.
Where Can I look for this type of Term? "Dependency Injection" I try looking solid principle in C# but found nothing about this. I have found it through someone's video he mentioned "DIP", "Interface Segregation Principle", etc. What is the exact name or keyword to find all related content concerning principles? Also thank you for the brief explanation about interfaces it helps me a lot understand the core concept of interface in C#.
Awesome explanation on interfaces and containers, kindly share a video link on containerization based on frameworks, any .Net framework is fine. Thanks
Thank you, fairly new to this. Very much from a procedural background. Dubious still of the whole OO Class based paradigm. Got lost on containers to be honest but will look further.
Thank you! For testing... Imagine that you are dependant on a service that gets stuff from a remote server through the GetStuffService. If you're doing unit tests, you don't want to actually go out and do that call to the remote server. To overcome that, you make an IGetStuffService interface and implement that in the GetStuffService. Now, for unit testing you make a MockGetStuffService that also implements the IGetStuffService. But this implementation just returns static data instead of going out to the remote server to get it. This makes the unit tests faster, predictable (you know what data is supposed to come back) and less prone to errors. Does that make sense?
Very good explanation. Showing how its accomplished without injection and then with injection help it click for me. Wouldve loved to see the example be carried all the way through with the container but Im sure you did that in later videos. Thank you!
Great video! I like to give real world examples with tangible things when I can. Do y'all have a go-to real world example of DI? Mine is the idea of a pen and ink cartridge. The high level overview of the explanation the pen doesn't care about what cartridge gets put in it as long as the cartridge implements ICartridge.
@@jfversluis thank you! You're doing great on these videos. I like the changes you've made like the lighting and some of the structure. It brings the videos to the next level!
Nice Gerald, fairly succinct. Now if you can do a video on Blazor Dependency Injection, specfically Server vs. WASM. Server is relatively easy, I have done that, but I had a research project that used server dependency injection and needed to use WASM and the way we setup D.I. in server is easy, but WASM was a bit more challenging. Would be great to see that and comment as well as with WASM you have all the specifics of D.I. with Scoped, Singleton, Transient, etc. I was using Mudblazor specifically the Dialog method. Ty
@@jfversluis Middlewares, different types of Filters, boxing unboxing, How linq will work, what are singleton, transient and scopes, still there are lot of concepts
i would love to know how to use a DI container to resolve a viewmodel against a ContentView. I have a system im place that works for ContentPages through a ViewModelLocator, but can't get it to work for views.
Thanks for the video, quick question, suppose we Inject and Interface `car`, which has implementation `make` into two different classes `ford` and `toyota`, so when using the method for injected interface how it know which method implementation to pick up from `ford` or `toyota`?
So in short it is a way of passing in a object that will be used instead of initializing an object within the class? What is the benefit of this over initializing something in a public static class and referencing that as needed, or storing methods in the static class to be used?
I love this channel , I learn a lot, I think a great topic to discuss will be how to use design patterns with xamarin, I always have struggle with that. Thank you very much.
@@jfversluis I 've been working for almost a year now in the states, and I assure that almost any pattern is useful, but by sure factory, decorator , observable, those will be great to know. I think the most used in xamarin will be adapter, cause we use adapter for list in xamarin native, but you know anything is useful, thank you very much for your time I really appreciate it.
@@jfversluis oops didn't mean that 😅 I was trying to refer the part at 9:39 where you mentioned that it's possible to implement automatic DI without frameworks, or maybe I misunderstood?
@@rushas Yeah I see what you're saying. Here's the thing: a plugin or library is nothing more than a way of making things easier for you. So in theory, you can implement everything by looking at the source of a library, add that to your source and don't need the library anymore. So sure, you can implement the automatic DI, but you will just be rewriting code that is already in a library somewhere. So in a way: you're building your own library 😉
Gerald please can you make a video or get me an orentation about how to create a sort by ascending or descending on listview. I am struggling to find something that could function.
Thank you Gerald, great video! I took a project over recently where not only such commonly used things like logging, but basically everything (e.g. business logic) was implemented as dependencies. It makes code changes a headache because every time I amend business logic, I have to start with modifying the interface first, then do actual implementation. Does it make sense to use interface-based dependency injection for business logic in your opinion?
Hm that sounds a bit like overkill. Do you have the chance to ask the original author(s) to ask what the reason for that was? Everything _can_ make sense. But like you say; if you feel less productive while doing so and you don't really have a compelling reason to keep doing then I would say: no, it doesn't make sense.
@@jfversluis Something related to architecture, so that I can easily swap out UI and/or Data Access Layers. I am learning about 3 tier design now to accomplish this but could use a good video such as this to help explain how to do it correctly. The other videos I have seen on here haven't been that great so far, but maybe I just couldn't find a good one. The tutorials I have seen so far were also a bit underwhelming and just didn't go into the depth I needed. If you could make it where you have 2 UI projects (Console and WPF perhaps) using the same Business Logic Layer, and 2 Data Access Projects (One for SQL, one for something like Azure cloud storage) that would be pretty neat. I need to see someone with more experience implement this properly. I believe the Repository Pattern is used in the DAL in this scenario, so that would be cool to hear you explain as an added bonus.
The value of interfaces clicked for me while watching this video, thank you so much for your easy to understand explanations!
