The Task Runner Explorer extension for Microsoft Visual Studio 2013 found the gulpfile.js in my project, but the task in that file where not listed, just beneath the gulpfile.js, (No tasks found) was displayed, this was caused by missing dependencies.
To fix this:
Just open a command prompt.
Change directory to the folder containing the file “gulpfile.js”
Then enter: npm install
All dependency for gulp should be installed, now when you op the project in Visual Studio 2013 the tasks should be shown.
