If you want to use the recently released Visual Studio 2015 preview together with Sitecore rocks for sitecore development, you won’t be able to install this plugin from the Visual Studio Extensions gallery: you won’t even find installable plugin while searching for the plugin.

With the introduction of Apps for SharePoint 2013 and the expansion of the SharePoint API, a whole new world opened for us, the SharePoint developers. This blogpost describes on how to integrate SignalR 2.0 into a SharePoint 2013 MVC app, with the possiblity to use SignalR from your hostweb! We will end up with a nifty SharePoint application that makes use of signalR and a remote event receiver, which uses the signalR hub to push through new items to every registred client. An example solution is provided at the end of the document, but imagine what you could do with this. I personally always include signalR solutions when building apps, to monitor all events that I am interested in when debugging/fixing apps.
