This helped me understand Unity and Dependency Injection better than most of the explanations found on the web. Simple and straight to the point. Thank you.

[@villanuevacarlos14]

This is the best video to explain Dependency Injection. You Sir deserves a cookie.

[@SenPradip]

Guruji, you made it so simple than others. That's the key for major attraction on you and your way of teaching. Thanks a ton SIR !!

[@mahreenafzal87]

It is one of the best video, I have ever seen on Unity framework. Simple and to the point.

[@CevicheChessSalsa]

This is the best video about dependency injection I have found out there. Your videos are very educational and keep up the good work. Congratulations !!!

[@SushrutKanetkar]

Amazing lecture! One of the best teachers ever ! Kudos Shiv !

[@alexchoiyl]

Very well explained, looking forward to part 2, thanks.

[@manishkjanu]

Thanks for sharing this knowledge. You simplified the things and it helps us to understand it. Waiting for second part of it where will use XML file for configuration of objects and also answer that why OracleDal object is injected during resolve of customer class.

[@gallieon8718]

Hi. Very grateful for your efforts. I can say I understood right from the first video. Please consider doing the next installment. it would be very helpful for a lot of us. Thanks again.

[@emanuelfaisca1783]

What you are doing is usefull. I finaly understood these concepts with your explanations!

[@shaikhzoyeb]

thank you so much it was a pretty good tutorial and i learned how to decouple an application by implementing DI IOC injections

[@rohitash4122]

Excellent video. Clarified several doubts.

[@zagroti]

Thank you for taking the time to explain the dependency injection.

[@ronnieullah]

another impressive explanation of a difficult theory. Very helpful. Please keep up the good work.

[@kopilkaiser8991]

Regular subscriber of yours by now. I've been actively watching your videos and one reason is I learn really well from your lecture, practical example and of course you have a brilliant talent overall to teach complicated ideas. I had been looking everywhere to learn DI and nowhere I could understand better the topic more better than I did here. Thank you for all the effort you had given to teach us fellow beginners. My best wishes for your best success.

[@tanmaymishra92]

Just FYI ... unity container now has been moved to a different namespace, called 'Unity' , so while searching nuget you will have to look for that, and microsoft.practices and all other dll wont show up in references, they all will be residing under the 'Unity' itself

[@seldom89]

Simple explanation yet very concise. Good job sir.

[@sanfordhoffman2392]

Very good video. Thank you for taking the time to explain this concept.

[@kamdemkakengne]

[@kopilkaiser8991]

I feel you brother. I had been feeling the same with understanding Dependency Injection. But now, I am feeling much better.

[@ramachandraaddala]

Hey Man, I gone through not less 5 videos to understand DI, but you are awesome in explanation and any dumb person like me can understand. I have posted in my LinkedInn and wishing you to keep good work continue.

[@urvashigutka5091]

Great...many vidoes just gives theoretical knowledge...u gave practical knowledge

[@zuzuba3481]

No words to appreciate bro.. thank you so much...

[@lisazhou7776]

[@seemamajoka1761]

Very good video for understanding DI.Thanks :) But i need to explore more Please continue sharing.

[@IlyaHoltz]

[@backupfolder1839]

Thanks so much! your videos are so useful...

[@rockingdude8383]

Excellent video. Best short video for dependency injection. Thanks a lot and let us know when is the 2nd part releasing :-)

[@Sonny0276]

Great Video. Thank you for posting.

[@escorpianoyqueee]

Nice video. Basically you need to 1) nuget unity, 2) register types somewhere at your startup and 3) use Resolve instead of new()... and that´s it

[@azmatali3308]

IOC explained elegantly.

[@jayaprakashmuthugopal1895]

Great Video.

[@padmaraj5803]

Good explanation thanks

[@redahamiti7577]

Hi, Here you can you use a simple Conditionnal Resolution via Unity, related to the example of the above nice Video: IUnityContainer objContainer= new UnityContainer(); objContainer.RegisterType(); objContainer.RegisterType("sql"); objContainer.RegisterType("oracle"); var Sql = objContainer.Resolve("sql"); var cust= objContainer.Resolve (new DependencyOverride(typeof(Idal), Sql)); cust.CustomerName = "inject Dependances"; cust.add();

[@dnfvideo]

@Abhishek here is the IOC video facebook.com/video.php?v=690253231015623

[@idanbudin3932]

Very clear explanation, though in my own opinion it would be better to cut some of the repetitions. I think your explanations are clear enough without reexplanations which made me kind of loose interest and feel that I am wasting time. Still good video after all, thanks! :)

[@shayakdutta8878]

So why did it decide to inject OracleDal and not SQLServerDal?

[@baartho]

+Shayak Dutta Because the OracleDal was the last one defined.

[@janjansen7957]

+Bartholomaus Bernsmann ok, can I define then SQLServerDal for injection without changing order of registration?

[@nanonerd100]

Pretty sure it injects the last item registered. Switch SQL and Oracle so SQL is last and SQL gets injected.

[@vd853]

Can I assume that if OracleDal cause an exception, it will use SQLServerDal instead?

[@raksp6763]

When registering the same interface multiple times however, the ordering does matter; in that case, each subsequent call to RegisterType will overwrite the previous registration for that interface.

[@AS-dc7hb]

it used the orace data layer by default. how we can use the sqldata layer in this example.

[@crisvega71]

no it is not by default I guess. It is because the last class associated by IDAL is ORACLE DAL

[@srini3993]

hi can you tell me - from where obj.container.resolve came to know that it is calling sql or Oracle???? it is used defined classes... how does utility came to know these??

[@sruthibalachandran387]

Very informative video. Could you please upload the next part soon and share us the link?

[@DanyalMalik54]

Nice VIdeo, i was looking for some one who can explain it from scratch with hands on example, Where is the next video that shows the use of config file??

[@dasharathamm1202]

Excellent one for dependency injectionm

[@vothuong08]

excellent video.Thanks so much. Where i can find next video ?I could not see after tried to search on youtube.

[@PremKumar-wv8xt]

super explanation sir

[@akshat_shakya_pro2797]

Dear Sir.. Please share the second video to configure through XML.

[@akron2000]

Nice tutorial. Where can I find the part 2?

[@suryakantsharma7999]

example neither too hard nor too simple just perfect

[@sandeepbrk]

Thanks. Great video. Very well explained in simple way..

[@jayantaghosh7678]

very very good explanation .. IoC

[@SushilSingh2005]

Wow never thought it was so simple....Where is the part 2??

[@TheMostBeautifulSights]

Thank you so much!

[@LiwaySaGu]

excellent!!!!

[@anilkale5138]

Video give better visual and conceptual understanding of DI.

[@nithinchandran7959]

how to handle many business objects such as customers, suppliers, agents etc in dependency injection? Should we add every object in the container

[@Ristogod]

Why is it necessary to watch the other DI IOC video when you repeat it all here?

[@basundhibiryani3546]

Resolve -- will be used in Service Locator pattern, Service Locator Technique is different from DI right ? Also what if we need SQL Server instance to be passed rather than Oracle instance ???

[@sale1609]

Very nicely explained. Can you please share the link for SOLID principle video. thanks.

[@neilvermeulen5283]

Thank you.

[@yousufanwer99]

sir please make second part of this video 1-Conditional Resolve 2-Load Configuration from config file 3- Life time management i am waiting

[@mdsiddic]

hi brother it's nice explanation... in mycompany I need to implement this concept as per my architecture advice .. could you please share second part of this video for condition resolve

[@dnfvideo]

Second part is available under .NET subscription, visit www.questpond.com

[@simtri8264]

Question - at 26:20 mins -- instead hwy not it create a customer object without constructor ?- why it automaticlly created with constrcuor and that to with OracleDal- we disn't called any injection for the constructor param wight ?
