Using Bundling (from Systelm.Web.Optimization) in ASP.Net WebForms causes issue

Question

I am trying to put in some optimization into my application by using BundlesCollection in my ASP.Net 4.0 application.

My style bundle contains 6 css files. The files are included into a master page. If I remove the CSS files from master page and instead put following:

<%= Styles.Render("~/bundles/css/default") %>

I am getting following error:

The Controls collection cannot be modified because the control contains code 
    blocks (i.e. <% ... %>).

There's a control for rendering bundles in webforms, just get the webforms optimization package from nuget: — Rafe, Apr 03 '14 at 19:09
