Code First Migrations With Existing Table

问题:

In my model I have navigation property Language:

public class IntegratorDescription : BaseContract
{
    [Key, Column(TypeName = "bigint"), DataMember]
    public long Id { get; set; }
    [DataMember, Column(TypeName = "bigint"), ForeignKey("Language")]
    public long LangId { get; set; }
    [DataMember]
    public string CompanyShortInfo { get; set; }
    [DataMember, Column(TypeName = "ntext")]
    public string CompanyInfo { get; set; }

    public virtual Models.Language Language { get; set; }
}

Language table already exists and it's done by another ORM, I need to say Migrations not to try to create Language table but update only Description table. How?

-"There is already an object named 'Languages' in the database."

-IGNORECHANGES

Scaffolds an empty migration ignoring any pending changes detected in the current model. This can be used to create an initial, empty migration to enable Migrations for an existing database. N.B. Doing this assumes that the target database schema is compatible with the current model.
