Alternative Managed API:

Do you know one? Please contribute it!


If you want to find the user logged in to the workstation, you consider instead a WMI query ("select UserName from Win32_ComputerSystem"), which has certain advantages (runs faster, less ambigious results, doesn't require Interop if using .Net 2.0 System.Management namespace, etc.)
