One (1) table with 3 Foreign Keys - Need to Reference

Question

This is my tables in SQL Server with Category table and need to be reference in Product table with 3 CategoryId.

What solution should I do? especially in Entity Core..

Do I need to 2 more tables for Category with the same content?

 

what I did to the entity is just like the code below but I'm not sure if this is correct or not..

 

public class Category

{

public Guid Id { get; set; }

public string Name { get; set; }

}

public class Product

{

public Guid Id { get; set; }

public Guid CategoryId2 { get; set; }

public Guid CategoryId3 { get; set; }

public string Code { get; set; }

public string Name { get; set; }

[ForeignKey("Category")]

public Guid CategoryId1 { get; set; }

public virtual Category Category { get; set; }

}
