I was trying to get a GitHub project working from scratch. These are the things I did to do that:

• Download and install NodeJS: https://nodejs.org/en/download
• Download any AngularJS project from GitHub
• Run a command prompt and navigate to the "client-app" folder: dotnet new angular -o "C:\Users\me\OneDrive\Documents\Visual Studio 2017\Projects\myproject\myproject-dev\myproject-client-app" --force
• Enter command: npm install -g @angular/cli
• Enter command: npm build fix
• Enter command: npm run ng
• Enter command: npm start
• Enter command: ng start --extract-css

(I didn't actually need to enter this last command, since npm start initiated this command for my project, but might not always be the case...)

In 'Startup.cs' file, replace

spa.UseAngularCliServer(..)

with

spa.UseProxyToSpaDevelopmentServer("http://localhost:4200");

Then F5 to start the ASP .NET Core project as we normally do to start debugging the application.

After all of that, the project should run.
