Is there a trick to getting Attributes to work? I followed both the video tutorials and the documentation in creating an attributes enum, but it is not recognized in the Unit Component. And if I create a new set with Tools > Apex > Attributes Utility, the message “loading new attributes file, please wait…” displays but never completes.
Are you using Assembly Definition files?
If so you can fix the issue by either editing the AttributesMaster.cs and changing the logic by which attribute enums are resolved, e.g. instead of var asm = markerAttribute.Assembly;
you will want to resolve the assembly that contains your specific enum.
Alternatively, place your enum in the same assembly as Apex Path.
