body: <p>I tried to create custom contact store at WP8. My code (from msdn):</p>
  
  <pre><code>     async public void AddContact(string remoteId, string givenName, string familyName, string email, string codeName)
      {
          ContactStore store = await ContactStore.CreateOrOpenAsync();
      }
  
      private void Button_Click_1(object sender, RoutedEventArgs e)
      {
          AddContact("0", "Sample", "Sample", "sample@tut.by", "32");
  
      }
  </code></pre>
