title: Change InputLanguage doen't work WPF
body: <p>I've problem with OSK in WPF. I change the InputLanauage by InputLanguageManager like this:</p>
  
  <pre><code>InputLanguageManager.SetInputLanguage(_targetKeyboardWindow, CultureInfo.CreateSpecificCulture("ru"));
  </code></pre>
  
  <p>But it doesn't work. I need to change the actual view of my application (by click back button) and then my changes in InputLanguageManager starts to work. But when I tried to change View from code-behind after I change input language - it does not work.</p>
  
  <p>Moreover, in debugger I can see that after changing language, the current language is still default (previous)</p>
  
  <p>Any idea?</p>
