MVC 4 Entity Framework 4 POCO:指定的架构无效

Question

以下是我似乎无法修复的错误：

Schema specified is not valid. Errors: 
The relationship 'Repository.ForumCategory' was not loaded because the type 'RepositoryModel.ForumCategories' is not available.

这是我的ForumCategory类：

public class ForumCategory
{
    //
    // Scalar Properties
    public int Id { get; set; }

    public string Name { get; set; }

    public int Order { get; set; }

    public virtual ICollection<Forum> Forums { get; set; }
}

这是我的论坛类：

public class Forum
{
    //
    // Scalar Properties
    public int Id { get; set; }

    public int CategoryId { get; set; }

    public string Icon { get; set; }

    public string Name { get; set; }

    public string Description { get; set; }

    public int ThreadCount { get; set; }

    public int PostCount { get; set; }

    public virtual Nullable<DateTime> LastPostDate { get; set; }

    public int Order { get; set; }

    //
    // Navigation Properties
    public virtual ForumCategory Category { get; set; }
}

这是我的RepositoryContext：

public class RepositoryContext : ObjectContext
{
    private IObjectSet<ForumCategory> _forumCategories;
    private IObjectSet<Forum> _forums;

    public SHRepositoryContext()
        : base("name=Repository", "Repository")
    {
        ContextOptions.LazyLoadingEnabled = true;
        _forumCategories = CreateObjectSet<ForumCategory>();
        _forums = CreateObjectSet<Forum>();
    }
    public IObjectSet<ForumCategory> ForumCategories
    {
        get { return _forumCategories; }
    }

    public IObjectSet<Forum> Forums
    {
        get { return _forums; }
    }
}

这是我的实体模型：

真的需要帮助，我读了一些人的回答，但似乎没有一个是相关的=\

问题是:我在模型中有一个关联覆盖了我的ForumCategory名称。解决方案是:我将关联重命名为Forum_Category，并将实体重命名为ForumCategory。这解决了我的问题！
