In explorer, I can see a bower.json and .bowerrc files at the root of the project directory. I can also see that you can manage packages within Visual Studio.
I'm guessing Visual Studio is hiding those bower files on purpose. I can't find settings to add another source in Tools>Options. Am I supposed to only use official bower packages? Is there a way to use a bower package from a local directory within Visual Studio's interface?
Right-click on the Dependencies in Solution Explorer and select Open bower.json.
In the bower.json file, I can add a new dependency like "example":"C:/path/to/my/bower/folder/"
