I tryed to run the starting material2 project and I had a similar problem with ngfactory. In main.ts I finded this comment:
`

AoT compile.
First run ./node_modules/.bin/ngc -p ./src/

`
After running that it worked, maybe you can try this.

@DzmitryShylovich what version of @ngtools/webpack are you using?

[DzmitryShylovich]

the latest 1.1.0

Basically I've just copy pasted test app so it might be Windows specific issue.

I have the same error. But if a try to go back to the beta16 I've got error:
webpack_1.NgcWebpackPlugin is not a constructor TypeError: webpack_1.NgcWebpackPlugin is not a constructor

I saw this same error also, when running ng serve -aot However, when I changed a file (added a new <p> ... </p> in app.component.html for instance) the error would not show after the project rebuilt. Making any other change would show the error.. and so on, alternately showing and not showing the error.
