title: Questions about ASP.NET Razor
body: <p>I am reading a book about ASP.NET MVC using Razor syntax and got confused about some codes that in the book. Just wondering what does that mean</p>
  
  <pre><code>@using(Html.BeginForm("AddToCart", "Cart")) {....})
  </code></pre>
  
  <p>Why use "using" key word here? Can anyone explain to me a little bit, thx.</p>
