EditorGuidelines: "Package did not load correctly"

Maybe this isn’t supported yet, but when I try to set a guideline in Visual Studio 17.1.0 Preview 1.0, I get:

The ‘EditorGuidelinesPackage’ package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file ‘C:\Users\username\AppData\Roaming\Microsoft\VisualStudio\17.0_e8dd53cc\ActivityLog.xml’.

Restarting Visual Studio could help resolve this issue.

ActivityLog.xml shows:
