<form method="post" @formname="contact" @onsubmit="AddContact">
    <div>
        <label for="name">Name</label>
        <InputText id="name" @bind-Value="NewContact.Name" />
    </div>
    <div>
        <label for="email">Email</label>
        <InputText id="email" @bind-Value="NewContact.Email" />
    </div>
    <div>
        <InputCheckbox id="send-me-deals" @bind-Value="NewContact.SendMeDeals" />
        <label for="send-me-deals">Send me deals</label>
    </div>
    <button>Submit</button>
    <AntiforgeryToken />
</form>

How do you do validation on this form because <DataAnnotationsValidator /> requires EditContext?
