How to update dll in asp.net
<p>I update my <code>freetextbox</code>  version into <code>3.3.0.22838</code>. I don't know how to update it. i just copy paste my new version in bin.</p>

<p>And I get this error:</p>

<blockquote>
  <p>Could not load file or assembly 'FreeTextBox, Version=3.1.5.21298, Culture=neutral, PublicKeyToken=5962a4e684a48b87' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)</p>
