"does not support framework DNXCore,Version=v5.0" after upgrading from beta8 to RC

[Daniel15]

After upgrading one of my projects from beta8 to the RC, I'm seeing these build errors:

Do I need to change dnxcore50 in my project.json to something else?

My fault, I had two global.json files. The one at the root correctly used rc1-final, but the one in RouteJs.Samples.Mvc used beta8. Using two different versions of the SDK resulted in this strange behaviour.
