Help Pluralsight update their video on Servicestack and/or the solution
Help Pluralsight update their videos on Servicestack and/or show how to update their example solutions to the latest version of Servicestack.
Another alternative is to offer an updated version of the videos example code localy (somewhere at servicestack.net/github.com).
I tried to do a update to the latest versions myself and I ran into loads of problems. To the extent that i gave up.
