I just pulled the Angular 5.0 release version. I'm running npm 5.5.1 and node 8.9. The download builds for dev from the command line without error.
From the command line, after the pull I ran "npm install", followed by "npm run build:dev" to verify the build is good.
To test the aot, I use Visual Studio and switched the target to "Release". The application starts up without an issue.

However, when I go back to the command line and execute "npm run build:prod" I get the following output :

webpack --config webpack.config.vendor.js --progress --color "--env.prod"

env = {"prod":true}

Ahh I didn't get to check in the correct NgTools plugin, fixing it now!
It needs to be using const AngularCompilerPlugin = require('@ngtools/webpack').AngularCompilerPlugin; in your webpack config.

Fixed via 0ab9dbf

Thank you! @consigliory @BillSheldon-HunterIndustries
