问Catel扩展EntityFramework5

EN

我使用Catel扩展EntityFramework5作为存储库和工作单元模式。我试图为派生类DailyMacroValue实现存储库，其中DailyMacroValue :DailyPrice

这是守则：

public class DailyMacroValueRepository :EntityRepositoryBase<DailyMacroValue, int>, IDailyMacroValueRepository
    {
        private XXXEntities _dbContext;
        public DailyMacroValueRepository(DbContext dbContext)
            : base(dbContext)
        {
            _dbContext = dbContext as XXXEntities;
        }

    }
    public interface IDailyMacroValueRepository : IEntityRepository<DailyMacroValue, int>
    {

    }
}

一旦我试图获得存储库，我就得到了超越：

在Catel.Data.DbContextExtensions.<>c_DisplayClass5.b_3() ( c:\Source\Catel\src\Catel.Extensions.EntityFramework5\Catel.Extensions.EntityFramework5.NET40\Extensions\DbContextExtensions.cs:line 116 )的System.Linq.Enumerable.FirstTSource

我确信这不是正确的实现方式，有人有继承实现的参考吗？
