ASP.Net 2012 Unobtrusive Validation with jQuery
<p>I was playing with Visual Studio 2012 and I created an <strong>empty ASP.Net Web Application</strong>, when I tried to add the <em>traditional validator controls</em> to a new page, this error occurs:</p>

<blockquote>
  <p>WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive).</p>
</blockquote>

<p>What are the steps to fix it?</p>

<p>This is my page markup:</p>

<pre><code>&lt;asp:Panel runat="server" ID="pnlUsername" GroupingText="Username settings"&gt;
    &lt;div&gt;
        &lt;asp:Label ID="usernameLabel" Text="Please enter your username" runat="server" AssociatedControlID="username" /&gt;
    &lt;/div&gt;
    &lt;div&gt;
        &lt;asp:TextBox runat="server" ID="username" /&gt;
        &lt;asp:RequiredFieldValidator ErrorMessage="The username is required" ControlToValidate="username" runat="server" Text=" - Required" /&gt;
    &lt;/div&gt;
&lt;/asp:Panel&gt;
</code></pre>
