Start with a model in the EF Designer and ensure there is some code that uses the entity to be refactored
1) Right-click on an entity on the design surface
2) Refactor -> Rename
3) Enter a new name and check the 'preview changes' checkbox
4) Preview pane is displayed but doesn't show any changes (see attached image)
Comments: Looks like this is related to T4 based code gen, if you revert to ObjectContext the preview pane works correctly.
