how to end ng serve or firebase serve

Question

I\'ve been doing web development with Angular2 and have been using both Angular2 and Firebase to run local servers. I haven\'t been able to find a command similar to typing quit

Answer 1

I was trying to run this from within the Visual Studio 2017 Package Manager Console. None of the above suggestions worked.

See this link where Microsoft states "The solution is not to use package manager for angular development, but instead use powershell command line. ".
