Synopsis of "Building Service Applications for SharePoint Server 2010" - SharePoint Conference 2009

This was tough to sit through just because service apps are so complex, but if nothing else, developers ought to watch it because Andrew Connell did such a great job presenting.  Basically, we went very quickly through each of the components that you would have to create to make a service app.  Again, it's very complex and there are a lot of components, so this is a must-watch if you're just going to be doing service apps in SharePoint 2010.
