We have seen cases where the admin admin db __MDrivenServer/App_data/DatabaseCompact.sdf has been corrupted between deploys and will not evolve correctly.
For this scenario a tool exists to help to move the admin_ECO_ORMAPPING from a similair/same versioned db into the corrupt one.
Download the db.
Use the tool found here: C:\CapableObjectsWush\source\AppCompleteGeneric\AppCompleteGenericFixCorruptAdminDB\
What the tool does is:
- given two compact dbs - read ECO_ORMAPPING into TextBox
- allow to read ECO_ORMAPPING from TextBox into db2
How to use: download db, find same version db, read ECO_ORMAPPING from correct - possibly manually update if no correct version is found - apply mapping to corrupt db.
