Как отключить использование таблицы __MigrationHistory в Entity Framework 4.3 Code First?

Я использую Entity Framework 4.3 Code First с настраиваемым инициализатором базы данных, подобным этому:

public class MyContext : DbContext
{
    public MyContext()
    {
        Database.SetInitializer(new MyContextInitializer());
    }
}

public class MyContextInitializer : CreateDatabaseIfNotExists<MyContext>
{
    protected override void Seed(MyContext context)
    {
        // Add defaults to certain tables in the database

        base.Seed(context);
    }
}

Всякий раз, когда моя модель изменяется, я вручную редактирую свои POCO и сопоставления, а также вручную обновляю свою базу данных.

Когда я снова запускаю свое приложение, я получаю эту ошибку:

Server Error in '/' Application.

The model backing the 'MyContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: The model backing the 'MyContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).

Используя EFProfiler, я также заметил выполнение этих запросов:

-- statement #1
SELECT [GroupBy1].[A1] AS [C1]
FROM   (SELECT COUNT(1) AS [A1]
        FROM   [dbo].[__MigrationHistory] AS [Extent1]) AS [GroupBy1]

-- statement #2
SELECT TOP (1) [Project1].[C1]          AS [C1],
               [Project1].[MigrationId] AS [MigrationId],
               [Project1].[Model]       AS [Model]
FROM   (SELECT [Extent1].[MigrationId] AS [MigrationId],
               [Extent1].[CreatedOn]   AS [CreatedOn],
               [Extent1].[Model]       AS [Model],
               1                       AS [C1]
        FROM   [dbo].[__MigrationHistory] AS [Extent1]) AS [Project1]
ORDER  BY [Project1].[CreatedOn] DESC

Как я могу предотвратить это?
