问题:

I have downloaded and install vscode in ubuntu 14.0 lts, and include existing node.js project. First think I have to do with vscode is debugging my app, for that I have go to debug (ctrl+shift+D) penal, configure launch.json file with "name" and "program"="app.js" properties. Put debug point in app.js file and click on run button. Here I am getting error "Cannot start OpenDebug because Mono (or a Mono version >= 3.10.0) is required". How to solve it?

Mono, cross platform, open source .NET framework, needs to be installed in the system. Please visit Mono - Download section and its corresponding installation guide to install.

Once installed you should be able to perform the debug operations.
