This is the <a href="http://connect.microsoft.com/VisualStudio/feedback/details/735928/in-asp-net-web-application-visual-basic-the-requiredfieldvalidator-doest-work" rel="noreferrer">official Microsoft answer from the MS Connect forums</a>. I am copying the relevant text below :-

When targeting .NET 4.5 Unobtrusive Validation is enabled by default. You need to have jQuery in your project and have something like this in Global.asax to register jQuery properly:

<pre><code>ScriptManager.ScriptResourceMapping.AddDefinition("jquery", 
 new ScriptResourceDefinition {
 Path = "~/scripts/jquery-1.4.1.min.js",
 DebugPath = "~/scripts/jquery-1.4.1.js",
 CdnPath = "http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.1.min.js",
 CdnDebugPath = "http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.1.js"
 });
</code></pre>

Replacing the version of jQuery with the version you are using. 

You can also disable this new feature in web.config by removing the following line:

<pre><code>&lt;add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" /&gt;
</code></pre>

It seems like there is a lot of incorrect information about the ValidationSettings:UnobtrusiveValidationMode value. To Disable it you need to do the following.

<pre><code>&lt;add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /&gt;
</code></pre>

The word None, not WebForms should be used to disable this feature.

More Info on <a href="http://msdn.microsoft.com/en-us/library/hh975440.aspx" rel="noreferrer">ValidationSettings:UnobtrusiveValidationMode</a>

Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

Type: UnobtrusiveValidationMode

Default value: None

Remarks:
If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.

Example:

<pre><code> &lt;appSettings&gt;
 &lt;add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /&gt;
 &lt;/appSettings&gt;
</code></pre>

Other than the required "jquery" <code>ScriptResourceDefinition</code> in Global.asax (use your own paths):

<pre><code> protected void Application_Start(object sender, EventArgs e)
 { 
 ScriptManager.ScriptResourceMapping.AddDefinition(
 "jquery",
 new ScriptResourceDefinition
 {
 Path = "/static/scripts/jquery-1.8.3.min.js",
 DebugPath = "/static/scripts/jquery-1.8.3.js",
 CdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.3.min.js",
 CdnDebugPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.3.js",
 CdnSupportsSecureConnection = true,
 LoadSuccessExpression = "jQuery"
 });
 }
</code></pre>

You additionally only need to explicitly add "WebUIValidation.js" after "jquery" <code>ScriptReference</code> in <code>ScriptManager</code> (the most important part):

<pre><code> &lt;asp:ScriptManager runat="server" EnableScriptGlobalization="True" EnableCdn="True"&gt;
 &lt;Scripts&gt;
 &lt;asp:ScriptReference Name="jquery" /&gt;
 &lt;asp:ScriptReference Name="WebUIValidation.js" Assembly="System.Web" /&gt;
 &lt;/Scripts&gt;
 &lt;/asp:ScriptManager&gt;
</code></pre>

If you add it before "jquery", or if you don't add any or both of them at all (<code>ASP.Net</code> will then automatically add it before "jquery") - the client validation will be completely broken:

<a href="http://connect.microsoft.com/VisualStudio/feedback/details/748064/unobtrusive-validation-breaks-with-a-script-manager-on-the-page" rel="noreferrer">http://connect.microsoft.com/VisualStudio/feedback/details/748064/unobtrusive-validation-breaks-with-a-script-manager-on-the-page</a>

You don't need any of those NuGet packages at all, nor any additional <code>ScriptReference</code> (some of which are just duplicates, or even a completely unnecessary bloat - as they are added automatically by <code>ASP.Net</code> if needed) mentioned in your blog.

EDIT: you don't need to explicitly add "WebForms.js" as well (removed it from the example) - and if you do, its <code>LoadSuccessExpression</code> will be ignored for some reason

In the Nuget Package manager search for AspNet.ScriptManager.jQuery instead of jquery. 
THat way you will not have to set the mappings yourself and the project will work with the click of a simple install.

Or disable the Unobtrusive Validation by adding this line to the Configuration tag of the web.config file in the project.

This error because in version 4.0 library belong to "asp:RequiredFieldValidator" exist but in version 4.5 library not exist so you need to add library by yourself

I was playing with Visual Studio 2012 and I created an empty ASP.Net Web Application, when I tried to add the traditional validator controls to a new page, this error occurs:

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

What are the steps to fix it?

This is my page markup:
