Javascriptservices: Angular CLI-based template: dotnet publish does not produce a website that can be run

[kadamgreene]

I installed the Angular CLI / Angular 5 based template as per these instructions, and then ran "dotnet publish" and attempted to run the output. Got the following error in console:

I'm using the same preview template and I haven't had any problems while publishing.

Here's your problem:

Hosting environment: Development

Once published, you need to run your app in production mode for it to work. https://docs.microsoft.com/en-us/aspnet/core/fundamentals/environments#development-staging-production
