I am really sorry for the inconvenience!
We are in the process of doing major infrastructural changes in JustCode so we can integrate the Roslyn platform into JustCode. That affects only Visual Studio 2015.
Unfortunately, not all features have been ported yet. Please, let us know what you are missing most so we can plan accordingly.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
