How to integrate SignalR 2.0 in a SharePoint 2013 MVC App

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.

I personally always include signalR solutions when building apps, to monitor all events that I am interested in when debugging/fixing apps.

As I was curious why this happened, I decided to check a few things out.

Customizing ADFS login for SharePoint 2010: how we did it

In SharePoint 2010 the possibility of claims based authentication was introduced. The out of the box experience of this functionality is often OK, for example in cases of corporate intranets and extranets, but it doesn’t always fulfill the requirements of internet facing websites which require authentication.  This blogposts describes why we wanted to implement the active login scenario and learns us what kind of problems we encountered (and nailed ;))
