Update-WindowsDefenderForRider -RiderHome $RiderHome

The value for $RiderHome can be found by following the docs https://rider-support.jetbrains.com/hc/en-us/articles/360006365380#h_fe327f48-579b-4073-b207-b7c6d67ff054

Note: only .exe and .dll from the 3 folders specified for Process exclusions. msbuild.exe and folder exclusions is already done by Rider

Do you really have to exclude the folders recursively?

I'm excluding all *.exe and *.dll in any folder recursively, because I didn't find anything in the Windows Defender docs that would allow to exclude processes in folders recursively. Anything like C:\bla\*\*.exe doesn't appear to work when checking their docs.
From all I understood until now: when you exclude a folder it will be recursively, but only very basic wildcard support for processes is available
