The reason this doesn't work in WPF is that these services are implemented in VB's WindowsFormsApplicationBase class, which isn't used in WPF applications. To do the same thing yourself:

Call WindowsIdentity.GetCurrent() to get the Windows user identity. You can get the name from this.

If you specifically want to set the thread principal the way the VB Windows Authentication option does, call Thread.CurrentPrincipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()) -- this is exactly what WindowsFormsApplicationBase does internally.

EDIT: If you prefer the My.User API, it looks like you should be able to do the same thing by calling My.User.InitializeWithWindowsUser(). I haven't tested this though.
