Defender slows down build times significantly.

You can set exclusions of course, but it does get tedious because every time you have a new project you need to add exclusions for its folder and the toolchain. Then every time a toolchain is updated (eg .../gcc/11.5 changes to gcc/11.5.2 you have to enter the 20 new exe exclusions and of course windows won't let you mass delete the old ones so it's click->confirm->click->confirm x50).

I might not do it myself but I can see why someone would just say "enough is enough".

You can use the powershell command Add-MPPreference -ExclusionPath[0] and ship a script with your app if you want. I do the same for Terraform providers - whenever a new version comes out, for a time the process can be randomly killed as I suppose a process that spawns a child process that starts talking to lots of endpoints looks somewhat suspicious.

In the old days at MSFT, developers had a separate HD for code and builds that was completely excluded from virus scanners.

Sometimes a big blunt hammer does the trick!

JetBrains does it for you with one click when you create a new project.
