How to integrate FluentValidation into MVC4

I have made a simple model that has FluentValidation in it but it does not seem to work. - My database is updating with empty name and passing `TryUpdateModel()` - I don't get client-side validation errors when I submit my form I have tried to add `FluentValidationModelValidatorProvider.Configure();` in `Application_Start()` but it shows that it cannot find `FluentValidationModelValidatorProvider` even though I added using class. I also tried to add `[Validator(typeof(Category))]` on top of my model class but didn't do anything. This us the resource I've been looking for information. Model ``` public class Category { public int ID { get; set; } public string Name { get; set; } virtual public ICollection<Image> Images { get; set; } } public class CategoryValidator : AbstractValidator<Category> { public CategoryValidator() { RuleFor(x => x.Name).NotEmpty().WithMessage("Category name is required."); } } ``` Controller ``` [HttpPost] [ValidateAntiForgeryToken] public ActionResult Edit(Category c) { var category = _db.Categories.Where(x => x.ID == c.ID).SingleOrDefault(); if (category == null) return HttpNotFound(); // Update model and return to category list if (TryUpdateModel(category)) // it passes with empty name and saves changes { _db.SaveChanges(); return RedirectToAction("index", "category"); } // Something is wrong, return view back return View(c); } ```
