ForeignKey error on composite PK model class - asp.net-mvc

Question

I've read ten post around this issue but still cannot understand what I am failing: I am stuck on this since two days.
ASPNET MVC5 web app. Code First
Models:
public partial class Category
{
public int ID { get; set; }
public string Name { get; set; }
public int? ParentID { get; set; }
public bool IsDeleted { get; set; }
public virtual ICollection<Product> Products { get; set; }
}
public class ISO_Languages
{
public int ID { get; set; }
public string code { get; set; }
public bool IsEnabled { get; set; }
public string name_en { get; set; }
public string name_fr { get; set; }
public string name_it { get; set; }
public string name_de { get; set; }
public string name_es { get; set; }
}
public class CategoryTrans
{
[Key]
[Column(Order = 1)]
public int category_id { get; set; }
[Key]
[Column(Order = 2)]
public int language_id { get; set; }
public string name { get; set; }
}
CategoryTrans has a composite PK based on two FK: Category ID and ISO_Languages ID
I am just trying to correctly reference this architecture in CategoryTrans model, that is something like:
public class CategoryTrans
{
[Key, Column(Order = 1)]
public int category_id { get; set; }
[Key, Column(Order = 2)]
public int language_id { get; set; }
[ForeignKey("ID")]
public virtual Category ID{ get; set; }
[ForeignKey("ID")]
public virtual ISO_Languages ID2{ get; set; }
public string name { get; set; }
The ForeignKeyAttribute on property 'ID' on type 'xyz.Models.CategoryTrans' is not valid. The foreign key name 'ID' was not found on the dependent type 'xyz.Models.CategoryTrans'. The Name value should be a comma separated list of foreign key property names
public class CategoryTrans
{
[Key, Column(Order = 1)]
public int category_id { get; set; }
[Key, Column(Order = 2)]
public int language_id { get; set; }
[ForeignKey("Category")]
public virtual Category catid{ get; set; }
[ForeignKey("ISO_Languages")]
public virtual ISO_Languages languguageid{ get; set; }
public string name { get; set; }
The ForeignKeyAttribute on property 'catid' on type 'xyz.Models.CategoryTrans' is not valid. The foreign key name 'Category' was not found on the dependent type 'xyz.Models.CategoryTrans'. The Name value should be a comma separated list of foreign key property names.
Am I trying to do something impossible?

Try:
public partial class Category
{
public int ID { get; set; }
public string Name { get; set; }
public int? ParentID { get; set; }
public bool IsDeleted { get; set; }
public virtual ICollection<Product> Products { get; set; }
public virtual ICollection<CategoryTrans> CategoryTrans { get; set; }
}
public class ISO_Languages
{
public int ID { get; set; }
public string code { get; set; }
public bool IsEnabled { get; set; }
public string name_en { get; set; }
public string name_fr { get; set; }
public string name_it { get; set; }
public string name_de { get; set; }
public string name_es { get; set; }
public virtual ICollection<CategoryTrans> CategoryTrans { get; set; }
}
public class CategoryTrans
{
[Key, Column(Order = 1)]
public int category_id { get; set; }
[Key, Column(Order = 2)]
public int language_id { get; set; }
[ForeignKey("category_id")]
public virtual Category ID{ get; set; }
[ForeignKey("language_id")]
public virtual ISO_Languages ID2{ get; set; }
public string name { get; set; }
}
