[@shenth27]

Great course if no advertising for his Master class every 5 mins

[@leonbaker1809]

Came here to say this. Tone it down, please

[@Chiramisudo]

💯!!! It's even more obnoxious that KZbin ads, and that's saying something.

[@smlambo3928]

Thank you this video. Helped me get into my second professional job as a software developer

[@HawkEncounters]

I got C# Masterclass course for my College Training so this will help me a lot to answer many questions in my exam. :)

[@tutorialsEU]

Good luck with the exam!

[@Robert723]

Hi Denis, Thanks for the video! I think you could include the 'Pause' clip about your complete C# course more often in this video.

[@martorulez]

:D :D :D :D :D :D

[@arkadiyshuvaev]

It is not polymorphism at 15:05 You should look at another video to understand this topic.

[@malindukumaradasa3851]

Very concise and understandable explanations. Great video! Thanks!

[@meosart1758]

Great video! Many thanks!

[@tutorialsEU]

Thanks. Hope you subscribe to not miss out our content

[@meosart1758]

@@tutorialsEU Of course))

[@andreilisovskii3414]

question 42 1:04:16 mistake in that particular example (if we assume exception within try { } block) Finally block won't execute, as you throw exception from catch block, and there is not catch earlier in stack.

[@davestorm6718]

Thanks! I noticed you have a bug in your CopyTo command (you copied it to itself instead of to marksCopy) should be int[] marksCopy = new int[3]; marks.CopyTo(marksCopy,0);

[@marcelositonio2495]

Outstanding! Thanks!

[@ethanr0x]

The video has some mistakes: 5. 08:14 You get to use the private field of a base class in a derived class because the derived class is nested in the base class. That's not normally the case for inheritance.

[@luis.e.moreno]

This is a great video! Thank you! Will you make more interview question videos? Topics like SOLID in C#, web API, .NET core, Blazor, MVC, etc. More Design Patterns would be nice too. I was asked in an interview what is the Yield keyword purpose. Only Break and Continue are in the video. Thanks 😀

[@i.eduard4098]

9:19 I am pretty sure you are not fully correct. You already have a property by using get set and it shouldn't be private, and by convention should be uppercase. It feels like you are a java developer and I know there you expose properties via get set methods. Fields are private and usually are named with an underscore and then you can have public properties using the fields in get set.

[@csperi-peri2447]

Great video - covering a wide variety of topics with code examples.

[@spiker9677]

Awesome with clear examples 👍

[@tutorialsEU]

I hope they will help you on your journey

[@amazingrays]

Nice video 🙏

[@sol-3uk]

Thanks for the video! Just thought I'd point out that for Q.39 it seems like you forgot to change the graphic in the bottom left.

[@parvati877]

Video starts at 1:39

[@MaciejKowalski-jr1ci]

Good content, but advertising is way too aggressive.

[@krishnakumargupta6993]

It's video very grateful for my interview

[@kwstaslalaounis3212]

Thank you!!!

[@kunnu9030]

[@tutorialsEUC]

For some reason the link didnt work anymore. I replaced it and it's this one: tutorials.eu/50-interview-questions-for-your-csharp-interview/

[@FrankPapadakis]

Lol, watching this video has made me feel like I need to study for a few more years before I should even think about interviewing. I feel so stupid 🥴

[@mageking4343]

sir smile is owsm

[@bittatamber]

Excited

[@sureshshindhe502]

Thank you very much

[@pranitapawar7707]

really nice video..can you make video for xamarin forms also

[@ChamaraIresh]

Nice video with clear examples

[@anon_148]

thank God a video about this where there is no Indian

[@paulc.8727]

what happened to 39 Explain var and dynamic?? 💨

[@seanleith5312]

never seen advertising like this, insert an ad every 2 minutes, crazy. Stop doing that.

[@stoploss-g6u]

Almost everyone giving car or bike example for abstraction😅

[@anon_148]

terrible

[@svlada84]

Video is great, but there is mistake on question 33. you should write: marks.CopyTo(marksCopy, 0); and not marks.CopyTo(marks, 0); and I test now this method create deep copy not shallow copy us you sad.

[@Joseph-ex4sf]

Appreciate the video but you put in way too many interruptions.

[@bornafrica7887]

Bro had to put an ad every 5 min.

[@samekamal-w9p]

Quick pause.

[@yesiamanerd2040]

With over 10 years as a Java programmer and 30 in tech, I advise managers against language trivia interviews. They don't reveal the best candidates, especially as tech evolves. Reject the trivia approach, and candidates should walk away from such interviews.

[@rowanabrahams9280]

I agree with this 101%

[@feifei1989]

Too many ads and pause. Annoying
