I've noticed that powershell.exe started csc.exe with a command line like this:
"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe" /noconfig /fullpaths @"C:\Windows\TEMP\pn1kld2d.cmdline"
I've read the CSC manual page, but didn't found any clues about what that @ sign does here.
Does anyone know the purpose of this @ sign?
