[WineHQ Bugzilla]

--- Comment #20 from Esme Povirk  ---
Managed C++ Assemblies work, but this particular one fails:

Unhandled Exception:
System.EntryPointNotFoundException: #680 assembly:<unknown assembly>
type:<unknown type> member:(null)
  at (wrapper managed-to-native) wyUpdate.VistaTools.IsUserAnAdmin()
  at updater.Form1..ctor (System.String[] args) [0x006e9] in

[DllImport("shell32.dll", CharSet = CharSet.Unicode, EntryPoint = "#680")]
public static extern bool IsUserAnAdmin();

Wine has this, so I'm guessing pinvokes by ordinal don't work correctly.
