title: Xamarin: Binding: property not found on 'Xamarin.Forms.ResourceDictionary', target property
body: <p>I'm developing an application using a MVVM pattern. Bindings works good but when I'm debugging my application on an Android device (I have not this log on iOS part), I have the following log:</p>
  
  <p>Binding: 'propertyName' property not found on 'Xamarin.Forms.ResourceDictionary', target property: 'typeOfpropertyName'.</p>
  
  <p>I don't necessarily implement the INotifyPropertyChanged interface in my classes because it depends on my needs. For example, I have a ListView with DataTemplate (a CustomViewCell) and ItemSource (Binding a List with multiple MyObject inside):</p>
  
  <p><strong>CustomViewCell:</strong></p>
  
  <pre><code>&lt;ViewCell&gt;
      &lt;ViewCell.BindingContext&gt;
          &lt;ResourceDictionary&gt;
              &lt;local:Converter x:Key="converter"/&gt;
          &lt;/ResourceDictionary&gt;
      &lt;/ViewCell.BindingContext&gt;
      &lt;Grid&gt;
          &lt;Grid.Resources&gt;
              &lt;ResourceDictionary&gt;
                  &lt;local:Converter x:Key="converter"/&gt;
              &lt;/ResourceDictionary&gt;
          &lt;/Grid.Resources&gt;
          &lt;Image
              Source="{Binding PictureImageSource}"/&gt;
          &lt;Image
              Source="{Binding User, Converter={StaticResource converter}}"/&gt;
      &lt;/Grid&gt;
  &lt;/ViewCell&gt;
  </code></pre>
  
  <p><strong>MyObject.cs:</strong></p>
  
  <pre><code>public ImageSource PictureImageSource
  {
      get
      {
          return ImageSource.FromUri(new Uri(MyUrl));
      }
  }
  
  public User User
  {
      get;
      set;
  }
  </code></pre>
  
  <p>With that code I have the following logs:</p>
  
  <p>Binding: 'PictureImageSource' property not found on 'Xamarin.Forms.ResourceDictionary', target property: 'Xamarin.Forms.Image.Source'</p>
  
  <p>Binding: 'User' property not found on 'Xamarin.Forms.ResourceDictionary', target property: 'Xamarin.Forms.Image.Source'                 </p>
  
  <p>I repeat everything works but I really want to remove those logs. Any ideas ?</p>
