How to serve minified WebForms.js and WebUIValidation.js?

I set debug="false" in web.config. And ScriptMode="Release" in ScriptManager on page.

But the following are still served unminified: 

<script src="https://ajax.aspnetcdn.com/ajax/4.6/1/WebForms.js" type="text/javascript"></script>
<script src="https://ajax.aspnetcdn.com/ajax/4.6/1/WebUIValidation.js" type="text/javascript"></script>

Here's my ScriptManager on page: 

<asp:ScriptManager runat="server" CompositeScript-ScriptMode="Release" EnableCdn="true" LoadScriptsBeforeUI="false"></asp:ScriptManager>

Please, without using the bundling process, how can I serve minified WebForms.js and WebUIValidation.js versions from aspnetcdn?

    It seems that aspnet CDN doesn't serve minified versions of WebForms.js and WebUIValidation.js. So I found a shorter way than the legacy Bundling and Minifying which works for me & thought to share in case any one will find it useful.

    The quick solution for me lies in minifying them myself, placing them locally, then calling them as follows: 

    <asp:ScriptManager runat="server" CompositeScript-ScriptMode="Release" EnableCdn="true" LoadScriptsBeforeUI="false">
        <Scripts>
            <asp:ScriptReference Name="WebForms.js" Assembly="System.Web" Path="~/Scripts/WebForms/WebForms_4.6.min.js"/>
            <asp:ScriptReference Name="WebUIValidation.js" Assembly="System.Web" Path="~/Scripts/WebForms/WebUIValidation_4.6.min.js"/>
        </Scripts>
</asp:ScriptManager>

    This will replace just these 2 with a minified local version while the other ScriptManager or Ajax scripts will be intact.

    Hi @Triangulumlightstar ,
    debug="false" enables bundling and minification at the same time.
    If you use CDN, you need to replace the local jQuery package with the CDN jQuery package.
    You can refer to Bundling and Minification.
    Best regards,

    Hi, sorry but I need to serve them from the CDN.

    I guess with the Bundling and Minification you mentioned, they won't be served from aspnetcdn.
