Invalid object name 'AutoHistory'

[R-oberto]

Hi. I'm having trouble getting this started in my project. My project could save prior to adding AutoHistory. Now I get the below exception on any save. There still is no table named AutoHistory in the database.
Microsoft.EntityFrameworkCore 5.0.15
Microsoft.EntityFrameworkCore.AutoHistory 5.0.8

Microsoft.EntityFrameworkCore.DbUpdateException: An error occurred while updating the entries. See the inner exception for details.

The solution was to run a migration. This updates the database schema. This should be part of the getting started instructions.
