WeatherAppIonic2 for VS 2015 is throwing error as not recognizing working directory as a Cordova-based project

[sultkon]

Error BLD105 The Cordova build did not recognize your working directory as a Cordova-based project. This is often because the "www" directory is not at the root of your project.

FYI
I am using VS 2015
Installed these dependencies

1. NPM task runner
2. TypeScript 2.0.6 editor
3. Microsoft ASP.NET and Web Tools Preview 2

However restoring packages did not work , so I had to run npm install from command prompt.
Now its showing no error on dependencies.
