I've watched another paid course (tho they offered free this month) that talked about this topic, but no one had taken the time to create examples like this to help clarify their teachings. Venkat is still one of the best.

[@anthonyodigie646]

This is the best explanation I have seen so far.
Been trying to grasp these concepts for months now, but I finally, fully understand them.
Thank you so much for this.

[@rulonoboyev2939]

14 dumbs don't think so

[@ANILKHANDEI]

No one had explained this concept so neat and clean. Hats off to your talent and the way you explain these topics so easily. It seems so simple but I know everyone who has read Microsoft docs has always wondered the actual meaning behind the technical jargons. While Microsoft docs are still my first place to understand your videos are like my personal mentor lessons. Thanks

[@akalutadesse6994]

You described and also showed with example the Singleton, Scoped and Transient methods that are a bit harder to grasp. Kudos! to Kudvekat.

[@pkplaypal]

I started my job by learning from Venkat's videos it's been more then 10 years, I always use to appreciate him for his work suddenly I needed to learn about this topic and I knew there will be only one guy who can clear this for me He is real Gem out there making things easy for us
Couldn't Thank him enough for this.

[@Kapoor123Shahid]

Thanks Venkat. You are one of the best tutor. Explaining complex concept great in detail. You spent maximum of your time with learning and teaching. God bless you.

[@eskandarrushdi5584]

[@Shpendi79]

Thank you sir, you are great, I'm happy to live with such as good lessons. And the best part is that this lessons are for free.

[@bmiller949]

I am using these tutorials to enhance my career technical knowledge. I was stifled by my previous employer and was unable to grow my technical knowledge. These courses are a huge help to me. There is a Starbucks gift card with your name written all over it. 😊

[@haimejoseph5210]

I wish i watched your video before my interview earlier. this could have saved me! still wishing for me to pass it. I now understand this thanks very much!

[@pardhasaradhivasamsetty7693]

This is bet example I have seen so far. It gave clear understanding. Thank you Venkat you are the best

[@janakagrawal]

This is the best video to get clarity on this topic. Watched few more videos but did not get clarity on this. Thanks.

[@adorebeauty6539]

This explanation is beast and better than other ones on the internet which are leaving us confused.

[@higherpurpose1212]

So to summarize, Singleton is STATIC which uses the same variable service. Scoped is per request but you have get and post in the same request so they use the service instance, and Transient is new and initialized for each and single request whether Get or Post, so one click of that create button issues a Get and a Post which meant 2 services created.

[@felipe0528]

You are the best Venkat ! Thanks alot!

Great as usual Venkat !
It's clear what is what, and what each and every of this method does.
Could you please explain, however, by using real cases *where* to use what, based on your experience ?

[@xahin96]

I'm also eager to know !

[@harag9]

It would be nice to know what sort of classes to use in which case. GlobalConfig type classes for Singleton, Helpers for Scoped, Transient - no idea - all others?
