I upgraded to the newest version of VS2022 17.8.0 and tried to compile my xamarin.forms ios application and get the following error

MT2002: Failed to resolve "System.Security.Policy.EvidenceBase" reference from "System.Security.AccessControl, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

This seems to work on the previous versions of VS
