Return Join Linq C #

I am trying to return a connection to my class and it gives me the following error.

Error 1 Could not implicitly convert type 'System.Collections.Generic.List' to 'System.Collections.Generic.List' C: \ Projetos_ASP.NET \ AdvanceTechniques \ Models \ Repository \ ProductRepository.cs 40 30 AdvanceTechniques

Executes the following code.

public List<Line> Get()
{
    return context.
        Lines.
        Join(
            context.Products,
            lines => lines.ID,
            products => products.LineID,
            ((products, lines)
                => new { lines, products}
        )).
        OrderByDescending(products => products.products.ID).ToList();
}

      

        
        
        
      

    

Follow my essence

public partial class Line
    {
        public Line()
        {
            this.Products = new List<Product>();
        }
