Looking for a workaround for:
Error: SQL71609: System-versioned current and history tables do not have matching schemes. Mismatched column: \'XXXX\'.
We just experienced this issue. We found a workaround by commenting out the system versioning elements of the table (effectively making it a normal table), building the project with the schema change we needed (which succeeds), and then putting the system versioning lines back in place (which also succeeds).
