Connect SharePoint Visual Web Parts

To connect web pats in SharePoint 2010 it requires creating interface, for example

   public interfaceITextCommunication

   {

       string Text { get; }

   }

then  provider

       [ConnectionProvider("Text Communication")]

       publicITextCommunication GetProvider()

       {

           returnthis;

       }

and consumer

       ITextCommunication provider;

       [ConnectionConsumer("Text Communication")]

       publicvoid ReceiveProvider(ITextCommunication p)

       {

           provider = p;

       }

This does not work in SharePoint 2013.

I would be very grateful for the help how to create connected web parts in SharePoint 2013.

Thanks in advance
