Startup.cs is no longer available with .NET 6 .. Microsoft has removed it and you have to configure services in Program.cs itself

[@RAHULRAJ-bs1ky]

Yes but by making a few changes in program.cs file we can bring start up.cs file into picture .

[@Abhishekmaurya-ol4iy]

There is only program.cs

Thanks and wc Syed

[@vamp9225]

You may consider splitting each lesson into a KZbin short and releasing them this way. I think this could help drive traffic to your channel. Each one is so concise and rich with information

[@interviewhappy]

Excellent idea... I will definitely do this soon. Please keep suggesting. All my implementations are originated from ideas of the viewers like yours only. Thanks again.

[@vamp9225]

@@interviewhappy what was most valuable for me was walking through the file structure, data flow and configuration. I come from a Java / spring background and have yet to find any good content that explains these beyond the superficial. Have you considered exploring testing? That is the next concept I would love to see detailed using your approach. Specifically API testing. Thank you again for the content it has been invaluable.

[@interviewhappy]

@@vamp9225 ​ going deep in testing will be slightly off the road, because my purpose is to clear the basics and then focus on interview important things. Testing is not so much asked, but I will consider this in near future.

[@experimentalSR]

add any unit testing related questions

[@interviewhappy]

Your Welcome Sir. Your words are inspiration .

[@kansaascollection]

I read all your questions still Object pooling, code to remove duplicate char from string, entity framework and Sp performance which is good and why

[@ankitbisht3794]

Please also cover those string array questions cause they are asked in many interviews for even experienced devs

[@zeeluck7128]

Excellent

[@AmrutDeshpandeM]

Hi Happy, In real-time project how to decide when to call AddScoped and AddTransient. Could you please give few example and any thought process we need to follow so in actual task what need to be used. Thanks Amrut

[@interviewhappy]

if your service needs to maintain state or hold data specific to a request or operation, use AddScoped to ensure that the same instance is used within that scope. For example, payment services. But if data is not there and no state then use Transient, for example DB connection services.

[@Hustle088]

In your dependency injection example suppose I want to call GetStudent() of MathStudent in FirstController and GetStudent() of ScienceStudent() in Second controller. How are we going to do it ? Since Both MathStudent and ScienceStudent using same Interface.

[@jayashreepatil9208]

great thanks u so much

[@interviewhappy]

Thanks Jaya. All the best for your career.

[@atulbhandari2786]

Great sir very effective tutorial . Very pls creata lot of vedio regarding the topics thanks sir for giving such a great knowledge

[@interviewhappy]

Thanks Atul. Sure I will create more videos so that every candidate can clear any .Net interview.

[@AmwayPratik]

A small rectification needed Sir, 32:30 TempData is used to pass data from Controller to COntroller, Please correct me If I am wrong Sir :) Apart from that this is very helpful video indeed, Thank you Sir 😇

[@kumarramas]

Very useful Thanks. Seems, TempData work is different (controller to controller)

[@valeriaarrieta1517]

Hi! great video! could you share the link of the presentation?

[@interviewhappy]

Thansk Valeria, yes I can but somehow I misplaced it. If I will find it, I will share.

[@SivaKumar-sy6vw]

Thank you for the best explanation.i haven't seen the pdf in discription, can I get this pdf

[@shangeet]

Hi, please clarify below queries 1. Is it possible to add same service as singleton and transient at same time? 2. Is it possible to add multiple services with different lifecycle in an application?

[@interviewhappy]

1. No I don't think so, you might get some error. 2. Yes, some service can be singleton others can transient.

[@shangeet]

@@interviewhappy Appreciate your quick reply!! Thank you!!

[@vibdib]

If user wants to go to index why should they enter newindex and then you internally route it to index. What is a practical scenario fir this

[@interviewhappy]

May be you don't want to reveal your action method names in url, because of security purpose.

[@vibdib]

@@interviewhappy give a practical case

[@sanjurocku9511]

Fantastic video.. really appreciate it.. it is very useful for instant understanding of the platform. Just one thing.. with the latest version of .NET startup file is removed so You can mention that too. Thanks again!

[@prabhgill4060]

Sir, At 21:18, you explain that run method is used to run the next method but it is used to terminate request pipeline.

[@Musiqqq]

he siimply wanted to say, "If you got more than one middleware remaining, use the "use" method. Finally call the Run method to execute and break the middleware chain. (No more middleware can be passed after run)"

Then you have to create separate interfaces for both of them and register them in startup class
