Entity Framework Seed method is not being called

Question

We are using Entity Framework 4.4 and using migrations. The database already exists and we need to update it on regular basis. The seed method, however, is not being called

Answer 1

The Migrations Seed method

runs whenever the Update-Database PowerShell command is executed

You need to call Update-Database not Add-Migration

Add-Migration scaffolds a migration file containing commands to migrate the database to a new version. It is empty because there are no schema changes to make. You do not need to call Add-Migration before calling Update-Database if all you want to do is seed
