When creating code first collections can you implement a custom class that implements ICollection. The code below is conceptual not actual
public class Product
{
public int ProductId { get; set; }
public string Name { get; set; }
public Category Category { get; set; }
}
public class Category
{
public int CategoryId { get; set; }
public string Name { get; set; }
//Want to Avoid This
public ICollection<Product> Products { get; set; }
//Use his instead of above
public ProductList ProductsInCategory {get;set;}
}
public class ProductsList :ICollection<Product>
{
public int DiscontinuedProductsCount
{
return internalList.Count();
}
//Icollection Methods Excluded
}

EF can indeed support any collection which inherits from ICollection. We create a deletable collection to support auto deletions and also create collections for child objects to keep the size of our main object smaller.
