Description

A clear and concise description of the problem...

After migrate my project from 8 to 9, when I use ng g c helloworld, generated files don't match with angular options.

In my angular.json, I have :

     "schematics": {
        "@schematics/angular:component": {
          "styleext": "scss"
        }
      }

But, angular cli generate a helloworld.component.css file.

🔬 Minimal Reproduction

• Generate a new project in angular@8
• Migrate it to angular@9
• Run ng g c helloworld
• Bad file is generated

@DefeninMaxime I've also bumped into this. It seems the property has been renamed to style.

In this case ng update change conf with a bad value

Change

"schematics": {
        "@schematics/angular:component": {
          "styleext": "scss"
        }
      }

to

"schematics": {
        "@schematics/angular:component": {
          "style": "scss"
        }
      }

Please fix the migration system to handle style instead of styleext
