Capture regressions in a consistent fashion much earlier.

None

Describe the solution you'd like

Exporting the CodeDom to a file (which would then be diffed or compared with a tool)would possibly unlock the detections of generation regressions that may result in breaking changes in the following scenarios.

• Metadata - removal of paths/types
• Naming changes that are breaking
• Multiple/repeated validations across languages as the dom could optionally be exported before or after the refiner.
