I'm looking to write an App on SharePoint 2013, and I'd like to be able to connect App Parts in the same way you can currently connect Web Parts -- through the connections menu, and ConnectionProvider / ConnectionConsumer attributes.

I can't find any examples or references to tell me whether this is possible, or whether a similar feature exists. Anyone know if this is possible, and if so, what APIs I need to know about?

An example use case; I stick two App Parts on a page; one contains a dropdown; the other contains a table. Changing the value in the dropdown changes the contents of the table.

Can anyone tell me if this is possible?


Apps don't have anything like this OOB but you could implement it in many ways. One could be using SignalR: http://signalr.net/ Create a channel and let the apps talking together.
