Mvvm cross 3.5 binding Show warring

Question

After updating my project to Unified API and MVVM Cross 3.5 stable ,I am getting the following warring message in the console for all button bindings...

I am binding like this.

try {
 this.AddBindings(
  new Dictionary < object, string > () {

   //all the command controls - such as buttons
   {
    btnXmit,
    "TouchUpInside cmdXmitClicked"
   }, {
    btnCancel,
    "TouchUpInside cmdBack"
   },

  });
} catch (Exception error) {

}

Please reformat your "error message", it's almost unusable ! — AFract, Feb 16 '15 at 13:06

You'll need to create a LinkerPleaseInclude.cs file with the following code:

public class LinkerPleaseInclude
{
    public void Include(ICommand command)
    {
        command.CanExecuteChanged += (s, e) => { if (command.CanExecute(null)) command.Execute(null); };
    }
}

EDIT (per my comment):

Hi thanks for the reply... It would be helpful for me if i know where i need to include this class. – Suriya Mar 03 '15 at 07:46
You just need to add it to your iOS project. – enjayem Mar 03 '15 at 15:20
