Now, the user wants a complete feature. That could mean creating a comprehensive guide or documentation, or perhaps developing an add-on feature using this library. Since the user hasn't specified, I should consider both possibilities. However, given the context, it's more likely they want a thorough explanation of the library's features and how to use them, possibly with a use case example.

Finally, summarize the importance of the full source and how it adds value beyond just the components, enabling customization and deeper integration within the user's existing systems. Make sure to highlight that while the example is simple, the library likely offers many more advanced features for complex scenarios.

[ForeignKey("CategoryID")] public int CategoryID { get; set; }

public decimal Price { get; set; }

public class InventoryRules : BusinessLogicEngine { public bool ValidateStock(Product product) { if (product.Price < 0) { throw new ValidationException("Price cannot be negative."); } return true; } } Design a form using TMS UI components (e.g., TMS DataGrid , TMS FormBuilder ):

public class ProductRepository : TMSRepository<Product> { public ProductRepository(DbContext context) : base(context) { }
