Declarative authorization in REST services in SharePoint with F# and ServiceStack

This post is a short overview of my talk at Belarus SharePoint User Group at 2013/06/27.

The primary goals were to find an efficient declarative way to specify authorization on REST service (that knows about SharePoint built in security model) and try F# in SharePoint on a real-life problem. Service Stack was selected over ASP.NET Web API because I wanted to find a solution that operates in SharePoint 2010 on .NET 3.5.
