Visual Studio 2015 autoprefixer - visual-studio

Question

I find Web Essentials autoprefixer not auto enough - I need to manually say it to add prefixes. Also it doesn't offer me prefixes when I'm writing .less or .scss.
Is there any extension or option to make it automatically add prefixes on css compilation from .less or .scss stage?
I've tried Web Compiler extension, but it doesn't support prefixing for sass, and says that it supports prefixing for less, but I've tried enabling autoprefix in compilerconfig.json while writing .less and it didn't add anything.
Is there something for visual studio? Or maybe I should dump it and use some editor + gulp?

I'm sure there will be an extension out there but it isn't too much work to create a Grunt/Gulp file to do your compiling for you. Task Runner Explorer will then manage the running of the file. Writing your own will give you the control and the flexibility that an extension will not.
Here is a sample using Grunt, taken from my post on the subject Getting started with Grunt, SASS and Task Runner Explorer
module.exports = function (grunt) {
'use strict';
grunt.loadNpmTasks('grunt-sass');
grunt.loadNpmTasks('grunt-autoprefixer');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
// Sass
sass: {
options: {
sourceMap: true, // Create source map
outputStyle: 'compressed' // Minify output
},
dist: {
files: [
{
expand: true, // Recursive
cwd: "sass", // The startup directory
src: ["**/*.scss"], // Source files
dest: "stylesheets", // Destination
ext: ".css" // File extension
}
]
}
},
// Autoprefixer
autoprefixer: {
options: {
browsers: ['last 2 versions'],
map: true // Update source map (creates one if it can't find an existing map)
},
// Prefix all files
multiple_files: {
src: 'stylesheets/**/*.css'
},
},
// Watch
watch: {
css: {
files: ['sass/**/*.scss'],
tasks: ['sass', 'autoprefixer'],
options: {
spawn: false
}
}
}
});
grunt.registerTask('dev', ['watch']);
grunt.registerTask('prod', ['sass', 'autoprefixer']);
};
