To be fair, Resharper has been showing developers how to convert code into LINQ for over a decade. Using ChatGPT seems to be way slower than having IDE integration and auto-refactorings available.
I actually paid for resharper for many years. However when I switched over to VS22 I decided to give it a shot without it. As its definitely still lacking compared to resharper I have been using ChatGPT to fill in the gaps. If I get charged for ChatGPT I will most likely go back to resharper as you said its IDE integrated and ChatGPT is not atm.
I wonder how soon MS will start including ChatGPT into visual studio.
Isn't that kinda already what Copilot is? Very similar product with a different name/label.
