sharepoint 2013 "System.Workflow.Activities.StateMachineWorkflowActivity' is obsolete:"

Experts,

I'm currently upgrading my SP 2010 platform to 2013. I have a state machine workflow built in VS that I'm unable to deploy to my 2013 platform. I'm receiving the following error:

'System.Workflow.Activities.StateMachineWorkflowActivity' is obsolete: 'The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*'

The error message seems to be clear, but from my research I'm a bit confused. This article explains exactly how to create this type of workflow in SP 2013:

http://www.splessons.com/create-state-machine-workflow-in-sharepoint-2013-using-visual-studio-2012/

My attempts of this give  me the error message above. How did these guys manage to create this workflow?

I'm not finding much support from SP developers who have run into this problem. I'd expect that it's a real thorn in people's side when it comes to upgrading. So my question really is, is it possible to run state machine workflows on SP2013 and if not, is there a decent migration utility that can help me transition to a new type of workflow. Or am I SOL and need to rebuild my workflow in .net 4.5?

Many thanks,

Thanks for your comment Walter Curtis.

From what I've read, you can run SP 2013 with the 2010 workflow solution. I thought the 2013 workflows manager was optional.
