Try to update the Coderr.Client library (the base library).
Ah wow, yeah, that was it. I had 1.0.6, 1.0.20 is available. Oddly it seems installing the aspnet module first/only, pulls in 1.0.6 as the dependency, rather than the latest. Yup, now I see a lot more options in there, even more things to play with now! Thanks again
