Always verify SHA with 7zip for non-MS sources.
It's best practice to verify SHA from multiple sources to ensure they match and not trust only a single source.
Some of these databases scrape VisualStudio themselves, and others just scrape from other scrapers.

SHA Databases:
https://my.visualstudio.com/Downloads (MS account required to search/view SHA)

https://www.heidoc.net/php/myvsdump.php (CA, USA)
https://www.whois.com/whois/heidoc.net

https://dnhash.net (NC, USA)

======= Verify SHA-256 with 7zip =======
https://www.7-zip.org/download.html
Install 7zip > right click ISO > CRC SHA > SHA-256
If the SHA-256 matches the one from visualstudio.com, then the file has not been tampered with since its official release.
