My umbraco site is MVC, I have Bootstrap.less files, and have put in place .dotlesscss dll and included the references to the handler in my web.config

<remove name="DotLessCss" />

<add name="DotLessCss" verb="*" path="*.less" type="dotless.Core.LessCssHttpHandler, dotless.Core" preCondition="integratedMode" />

Then in my Config folder - clientdependency.config I added:

<clientDependency version="1" fileDependencyExtensions=".js,.css,.less">

And in my view I have:

@using ClientDependency.Core.Mvc
@{
    Layout = null;
    Html.RequiresCss("/less/responsive.less");
    Html.RequiresCss("~/less/bootstrap.less");
}

@Html.Raw(Html.RenderJsHere())

This all works fine, when debug is off, but when it's on the clientdependency kicks in and breaks the styling.. it's like the .less files aren't compiled when going via client dependency.

Any ideas on this? Anyone got this working?
