Le migrazioni di Entity Framework 6 possono includere una transazione attorno agli script?

Questo è quello che sto usando solo in modalità di rilascio per generare gli script:

public class MigrationScriptBuilder : SqlServerMigrationSqlGenerator
{
#if !DEBUG
    protected override void Generate(SqlOperation sqlOperation)
    {
        Statement("GO");

        base.Generate(sqlOperation);

        Statement("GO");
    }

    public override IEnumerable<MigrationStatement> Generate(IEnumerable<MigrationOperation> migrationOperations, string providerManifestToken)
    {
        yield return new MigrationStatement {Sql = "BEGIN TRAN"};

        foreach (var migrationStatement in base.Generate(migrationOperations, providerManifestToken))
        {
            yield return migrationStatement;
        }

        yield return new MigrationStatement {Sql = "COMMIT TRAN"};
    }
#endif
}

Dovresti collegarlo a DatabaseMigrationsConfiguration . Esempio:

public sealed class DatabaseMigrationsConfiguration : DbMigrationsConfiguration<DatabaseContext>
{
    public DatabaseMigrationsConfiguration()
    {
        SetSqlGenerator("System.Data.SqlClient", new MigrationScriptBuilder());
    }
}
