我正在使用Entity Framework 5和Code First Migrations.我有一个DataStore类派生自DbContext:

public class DataStore : DbContext, IDataStore
{
    public int UserID { get; private set; }

    public DataStore(int userId, string connectionString) : base(connectionString)
    {
        UserID = userId;
    }

    public virtual IDbSet<User> Users { get; set; }

    // Rest of code here
}

还有一个创建类实例的工厂DataStore类:

public class DataStoreFactory : Disposable, IDataStoreFactory
{
    private DataStore _database;
    private int _userId;
    private string _connectionString;

    public DataStoreFactory(int userId, string connectionString)
    {
        _userId = userId;
        _connectionString = …
