Web Essentials, web coding with Visual Studio
If you regularly use Visual Studio for your web development, you've probably realized that it is clearly not the greatest ally, even with the improvements brought over versions.
The top in all this is that the project is open source and available on GIT, so you can participate in its development by cloning on your machine and installing the Visual Studio SDK provided by Microsoft.
You will find all necessary information on the project site or download the latest version here. Remember that it is also possible to subscribe to nighty updates to enjoy the latest additions and corrections before others.
