I developed two features, one should deploy a workflow. After hitting F5 in Visual Studio 2012, I get a NullReference-Exception. Here is the output shown:

I installed the WorkflowManager and configured it to run properly (I hope so!). Any Ideas?
Here you find the message in the Logfile after trying to activate the workflow feature on SharePoint:
