مشکل در عدم ایجاد جداول در دیتابیس با EntityFramework

سلام دوستان
من با استفاده از mvc , EntityFrameWork 6 میخوام جداولم رو در دیتابیس ایجاد کنم اما این پیام برام داده میشه لطفا کمک کنید :

Introducing FOREIGN KEY constraint 'FK_dbo.PhysicalContents_dbo.Categories_Category_I d' on table 'PhysicalContents' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
Could not create constraint or index. See previous errors.

 public  class PhysicalContent

    {

        public virtual Guid? Id { get; set; }

        public virtual string FileName { get; set; }

        public virtual int Size { get; set; }

        public virtual string Extention { get; set; }

        public virtual string  Url { get; set; }

        public virtual Guid CategoryRefId { get; set; }

        public virtual byte[] RowVersion { get; set; }

        public virtual Person Person { get; set; }

        public virtual About About { get; set; }

        public virtual Article Article { get; set; }

        [ForeignKey("CategoryRefId")]

        public virtual Category Category { get; set; }

        public virtual Contact Contact { get; set; }

        public virtual SocialNetWorks SocialNetWorks { get; set; }

        public virtual Video Video { get; set; }



    }

}

 public class Category

    {

        public virtual Guid Id { get; set; }

        public virtual string Name { get; set; }

        public virtual string NameEn { get; set; }

        public virtual byte Order { get; set; }

        public virtual Enums.DeleteState DeleteState { get; set; }

        public virtual byte[] RowVersion { get; set; }

        public virtual DateTime? AddedDateTime { get; set; }

        public virtual ICollection<Category> SubCategory { get; set; }

        public virtual ICollection<Service> Services { get; set; }

ممنون بایت پاسخی که دادین
این fluent api برای physicalcontent من هست ببینید درسته :

کد HTML:

---

[HTML]
public PhysicalContentConfig()
        {
            HasRequired(x => x.Category).WithMany(s => s.PhysicalContents).WillCascadeOnDelete(false);
            Property(x => x.Extention).HasColumnType("varchar").HasMaxLength(4).IsRequired();
            Property(x => x.Url).HasColumnType("nvarchar").HasMaxLength(250).IsRequired();
            Property(x => x.FileName).HasColumnType("nvarchar").HasMaxLength(55).IsRequired();
            Property(x => x.Size).IsOptional();
            Property(x => x.RowVersion).IsRowVersion();
        }

[/HTML]
باز هم همان خطا را می دهد
