We're seeing the same thing - our compilation times literally double because of Defender activity, you can go into resource manager and see defender using like 50% of the CPU, it takes our project from about 12 minutes for a full rebuild to 25 minutes. And the thing is - you can add whatever exceptions you want, they work for a while and then it breaks again with updates, I literally keep having to re-add and fix exceptions in Defender every month or our compilation times slow down to a crawl.

JetBrains IDEs actually tell you to exclude some directories from Defender (and will even do it for you in some instances) because of performance issues. DevDrive[1] fixes that since it's excluded from defender by default.

I've used Rider to add the folder as an exclusion, no dice.

I'm going to give dev drive a go, but forgive me for being sus for enabling a feature for a problem that MS seem to have caused.
