New Post: MVC Function Data Annotations aren't being rendered into page

Thank you for the information!

Also, if you don't want to set these parameters globally (in ~/web.config), you can try and set them at the application level in the individual views (.cshtml) you need:

@{
    HtmlHelper.ClientValidationEnabled = true;
    HtmlHelper.UnobtrusiveJavaScriptEnabled = true;
    // ...
}
