You can install AngularJS in a solution either manually, by downloading the AngularJS framework, or using the Bower package manager. To open an application that is organized in the directory structure and does not have a solution file, press Ctrl+O or choose from the main menu, and then specify the root folder of the application. Make sure the Angular and AngularJS plugin is enabled on the Settings/Preferences | Plugins page, tab Installed, see Managing plugins for details. For AngularJS entities, use the Go To Symbol navigation. You can use built-in AngularJS live templates and navigate between the name of a controller in HTML and its definition in JavaScript or between ngView or &routeProvider and the template.
