How to dismiss keyboard in WP, when „Enter-Key“ is pressed?

Unbelievable, but true:
Since I work with XF, the Keyboard in WP don’ dismiss, when the “Enter-Key” on the soft-keyboad is pressed (while it works without problems on iOS and Android). I also have filled a bug therefore some months ago...

Problem description:
If I have an Entry or a SearchBar on a page, the keyboard is showed, as soon as the Entry/SearchBar has the focus.
The user can type in text and the press the “Enter-Button” on the soft-keyboard… and… nothing happens...(the keyboard is showed until, the user tap on another element on the page)

As this behavior is not usable in a productive App, I have searched by try-and-error and found a workaround, that seems to work.
Add an .Completed-event to your Entry/SearchBar and disable/enable the Entry/SearchBar when the event-fires.
Example-code:

MyEntry.Completed += (sender, e) =>  // Event is fired, when the “Enter-Key” is pressed
{
  if (Device.OS == TargetPlatform.WinPhone) // Do it only for WP (as iOS and Android works)
  {
     MyEntry.IsEnabled = false;  // Disable Entry -> Seems to cause the Keyboard to dismiss
     MyEntry.IsEnabled = true; // Re-enable Entry
  } 
};

Notes:
This is a workaround that seems to work for now...
As soon, as Xamarin have implemented the correct handling, this should be removed from code.

Hope this helps someone…
