LESS : Dynamic CSS language

Recently come across the using LESS in one of my project. LESS looks very cool and provides the programming capabilities to CSS. Like using LESS in CSS, we can define variables, functions and much more and reuse them across the multiple css pages.

By default every CSS page is a less page.

We can achieve the LESS in a project in two ways.
1.Client side.
2. Server side.

Client side: It will costs the performance cost. Because when ever user requests a page browser needs to convert css file to LESS.

Server Side : when you add the LESS the less at server side it will automatically converts the CSS to LESS while building the application.

You can download the "dotless" package from Nuget.

For more Information, Please refer below reference urls

LESS -> http://lesscss.org/
LESS in dot net -> http://www.dotlesscss.org/

HAPPY CODING :)

How long the view location will be cached in MVC?

The default cache is 15min.

we can extend this using follwing code in Global.asax

var viewEngine = new RazorViewEngine
                         {ViewLocationCache = new DefaultViewLocationCache(TimeSpan.FromHours(24))};
    ViewEngines.Engines.Clear();
    ViewEngines.Engines.Add(viewEngine);
