Drop, create, and seed an EntityFramework database for unit testing

DropCreateAndSeed.vb

Imports System.Data.Entity
Imports System.Data.Entity.Migrations

Public Class DropCreateAndSeed(Of TContext As DbContext, TMigrationConfiguration As {DbMigrationsConfiguration(Of TContext), New})
    Implements IDatabaseInitializer(Of TContext)

    Public Sub InitializeDatabase(context As TContext) Implements IDatabaseInitializer(Of TContext).InitializeDatabase
        Dim step1 = New DropCreateDatabaseAlways(Of TContext)()
        step1.InitializeDatabase(context)

        Dim step2 = New MigrateDatabaseToLatestVersion(Of TContext, TMigrationConfiguration)()
        step2.InitializeDatabase(context)
    End Sub
End Class

When writing unit tests for an EntityFramework application, it's helpful to reset the database to a known state at the start of the unit tests. Entity framework has a DropCreateDatabaseAlways class that resets the database, but it doesn't call the Migration.Configuration.Seed() function. It also has a MigrateDatabaseToLatestVersion class that calls the Seed function, but it doesn't reset the database. This class does both.
