I am using System.DirectoryServices.AccountManagement.UserPrincipal.Current.EmailAddress in my code, that’s why I need to import the namespace System.DirectoryServices.AccountManagement.
For two xamls the import is working, but wierdly not for the last one.
For the import I added
to their xamls.
I also tried to install the namespace as a package, but the installation always fails, whichever version.
My studio is version 2019.10.2
Any help is appreciated.
