You give code examples but do not run them???

[@interviewhappy]

I focus on explaining. Writing code, run that you should. That's how we learn.

[@Yahweh5995]

Legendary comment 🙌

[@Asivakumar503]

Nice explanation. But this explanation shows the rules to use out and ref keywords in c#. It's not an explanation for differences.

[@interviewhappy]

Thanks Siva for bringing this up. Soon I will revise this and add more differences

[@itx__tallal2133]

[@WaqasMehmood-nq5uz]

@interviewhappy

[@akhtarraz]
