It seems that a couple of days ago (17th October), a new version of SignalR was released (version 2.0.0), which uses a new version of Microsoft.OWIN.Security that requires .NET4.5. To get around this, I simply installed the previous version (1.1.3) using the following Package Manager Console command:


install-package Microsoft.AspNet.SignalR -Version 1.1.3
