What are some effective input validation techniques in MVC?

In MVC, you can use techniques like data annotations, model binding, and custom validation attributes to ensure input is valid.

Can you explain how data annotations work?

Data annotations are attributes you can apply to model properties to enforce validation rules, like [Required] or [StringLength].

What is model binding and how does it relate to validation?

Model binding maps form data to your model, and it automatically applies validation based on the data annotations you've defined.

Are there any best practices for implementing these techniques?

Yes, always validate on both client and server sides, keep validation logic centralized, and provide clear error messages to users.
