how work

@html.validationmessagefor(model => model.deadline)

the validation rules set within entity mapping don't bubble ui you're suggesting in code. rules you've specified used create , validate entity before saving database.

if wish validate entity using @html.validationmessagefor() helper occurs on ui layer , instead uses asp.net mvc's info annotations set validation rules, so:

public class product { [stringlength(50),required] public object name { get; set; } [stringlength(15)] public object color { get; set; } [range(0, 9999)] public object weight { get; set; } }

ultimately, want treat entity separate object gets passed ui, mapping entity view specific model such view model. you're able add together validation attributes highlighted in reply above view model there may circumstances 1 form requires field required, form might not.
