Less for Dot Net - Asp.net

Introduction

Just hit an interesting utility, LESS Compiler for .net (asp.net)
So you can leverage the power of less (Dynamic CSS) in your .net web applications

Usage

Just add the following to the Web.config

<add type="dotless.Core.LessCssHttpHandler,dotless.Core" validate="false" path="*.LESS" verb="*" />

<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler,dotless.Core" />

So, now you added a handler for .less files

Then configure it

<dotless minifyCss="false"
 cache="true" />   

*You can also use it from the code

Less.Parse("div { width: 1 + 1 }");

which will produce 

div {
  width: 2;
}
