@atiq-bs23 Thanks for your help. How did you find all these places, manually or by some code analysis utilities?

@RomanovM Have you thought about using a github action workflow to run linting check on new PRs so that this is taken care of automatically?

[RomanovM]

@danFbach Yep #5538

Okay 👍

@RomanovM yes, using visual studio code cleanup.

@RomanovM
I have some previous development experience with you, and I know that nopCommerce follows best practices.
While exploring your recent changes, I ran Visual Studio's default Code Analysis and Code Cleanup.

This process affected many files, mostly by changing their size. However, I noticed a few files that had meaningful changes, such as adjustments to spacing and alignment, sorting using references in ascending order, and removing unused references.

I included only these meaningful changes in the commit.
