I'll mark this as a bug.

Already looking into it and looks like due to mixing DataTables.AspNet.Mvc references to dnx beta 4 with newer dnx beta 7 items.

[Anderson Matos]

This was related to multiple frameworks being referenced (beta4 from DataTables.AspNet and beta7 from your code).
Fixed after project was moved to beta8. Follow these instructions to upgrade your existing code: http://wildermuth.com/2015/10/20/Upgrading_from_ASP_NET_5_Beta_7_to_Beta_8
