Web Extension Pack extension for Visual Studio 2015
Before Visual Studio 2015, if there was only a single extension for Visual Studio that every web developer had to install that, it was Web Essentials. For every other extensions we usually have to download and install them individually.
But fortunately for Visual Studio 2015 a new extension pack has been introduced which in fact is a collection of very useful other plugins (Web Essentials 2015 included) specially for web development. The name is Web Extension Pack and is another super cool work by Mads Kristensen!
To know the list of plugins and the functionality of each, have a look at the description in the page. Make sure to check out the detail of each extension to make the best use of them.
