Update the "Self-Tracking Entities code" from the database

• open a ".edmx" file
• right click on an empty area. From menu select "Update Model from Database"
• add any new tables and run the update
• Did a rebuild (might not be important)
• in "Solution explorer" right click on "SelfTrackingEntities.tt". From menu select "Run Custom Tool" (first .Data, then .DataTransfer)
