Bring a window to the front in WPF

by

How can I bring my WPF application to the front of the desktop? So far I’ve tried:

SwitchToThisWindow(new WindowInteropHelper(Application.Current.MainWindow).Handle, true);

SetWindowPos(new WindowInteropHelper(Application.Current.MainWindow).Handle, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

SetForegroundWindow(new WindowInteropHelper(Application.Current.MainWindow).Handle);

None of which are doing the job (Marshal.GetLastWin32Error() is saying these operations completed successfully, and the P/Invoke attributes for each definition do have SetLastError=true).

If I create a new blank WPF application, and call SwitchToThisWindow with a timer, it works exactly as expected, so I’m not sure why it’s not working in my original case.

Edit: I’m doing this in conjunction with a global hotkey.
