I followed this tutorial
And then did
Update-Database -Force -Verbose
It showed that it upgraded the table. However an error is shown:
The model backing the 'DbConnection' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).
I also tried
Enable-Migrations -ContextTypeName MvcApplication6.Models.DbConnection
However it says:
Migrations have already been enabled in project 'MvcApplication6'. To overwrite the existing migrations configuration, use the -Force parameter.
Any ideas what I did wrong?
