升级后的EF 4.1代码优先问题

Question

好的,所以我刚刚通过NuGet升级到EF Code First 4.1,现在我的JobSiteContext.cs类中出现了以下构建错误:

"当前上下文中不存在名称'DbDatabase'"

这是我的代码:

public class JobSiteContext : DbContext
{
    public DbSet<JobSite.Models.Job> Jobs { get; set; }

    public DbSet<JobSite.Models.Location> Locations { get; set; }

    public DbSet<JobSite.Models.Profile> Profiles { get; set; }

    public JobSiteContext()
    {
        // Instructions:
        //  * You can add custom code to this file. Changes will *not* be lost when you re-run the scaffolder.
        //  * If you want to regenerate the file totally, delete it and then re-run the scaffolder.
        //  * You can delete these comments if you wish
        //  * If you want Entity Framework to drop and regenerate your database automatically whenever you 
        //    change your model schema, uncomment the following line:
            DbDatabase.SetInitializer(new DropCreateDatabaseIfModelChanges<JobSiteContext>());
    }
}

谁能指出我正确的方向？

谢谢保罗
