Have you ever used Dependency Injection? Do you like it? Let me know what you think!

[lnagy]

this is more like a real life example, I'm tired of all the animal and car examples.
short and sweet, now I can understand it from a theory perspective.

thank you!

[RushAustin]

THIS is the way to introduce dependency injection! I really appreciate showing the traditional method, explaining D.I.P. and implementing the interface. Really helped me understand the basic principals.

5:44-5:48 had to hear it 3 times and I am like "ooooh, I get it now" thank you very much.

[sabitkondakc]

I made a drastic change in my career path from Physics Engineering to Software, OpenSource and other sharing cultures in this field stick out from the rest, thanks for your contribution, I'll have mine in years to come, stay afloat :)

I struggled to grasp exactly what the Dependency Inversion principle meant. Thank you for the simple and straightforward explanation ❤

[nickben]

This is the best explanation I have seen of Dependency Injection.

This video should have a minimum of a million views. What an amazing video!

[sushma]

An instructor who uses light IDE theme! That's just what I needed.

[fabio_davilla]

you helped me in a way I can't even explain, thanks a lot!

[RKO]

Just wanted to say how useful this was in explaining a topic I was otherwise struggling to understand! Thank you!

[DotNetCrunch]

Now that is what we call a short but up to the point explanation!! Kudos..!

[aks]

Short, sweet and to the point. Thank you

[jacobclark]

Ok for some reason no one else could explain this to me and now I understand it and feel like its so simple. Appreciate you

[FANTAZSYREV]

I know you made this 4 years ago, but as a SE student learning about OOP this is a huge help. Ty!

[KDOERAK]

A great example: short, simple yet explaining the essence of DI. Not many are capable of doing this.

[fisnik]

This is best explanation about D.I I've come across!
Thanks a lot Claudio!

[igor]

Thank you Claudio Bernasconi, finally got the point about Dependency Injection and I'm grateful about that.

[alkishadjinicolaou]

Can we use DI to pass data between pages. What happens when the use reloads the pages. I know that for Blazor Server for example the connection is lost so the data is lost.

[ITGUY-bu]

wow thank you soo much you make it soo easy to understand I did not understand in the first time when I watched the video but when I watch it again and focus, I understand it so much
