Using Get-ADUser but 3.0 needs a filter? What changed?

I'm trying to just do a basic query of AD attributes from a text file of SamAccountNames I have, but I'm upgraded to PowerShell ISE 3.0 and there might be some things new I'm not understanding. 

I was just trying to do something simple like this; Get-Content C:\Scripts\userabrivs.txt | ForEach { Get-ADUser -Properties * } | Export-csv C:\scripts\Output\adusers1 

but in ISE it always asks for 

I'm not very good at this so can someone help me understand why it needs a filter when I'm just asking it to use the list of SamAccountNames I have in a text file?
