Repro steps

• Step 1

ng new myproject using the latest angular-cli

• Step 2

Make a type error in app.component.ts like

export class AppComponent {
  title: NotAType = 'app';
}

Observed behavior

The type error appears in an IDE with Typescript support.

• ng lint does not show the type error
• ng lint --type-check as mentioned in other issues I found results in an error: Architect commands with multiple targets cannot specify overrides. [...]
• ng lint myproject --type-check to appease the Architect error still does not show the type error
• tslint --type-check --project . shows the type error but mentions a deprecation warning. More info.
• tsc --noEmit shows the type error

Desired behavior

I expected ng lint to show type errors. As a new user to Angular it seems to be the one and only interface from the command line intended to answer "is there anything syntactically wrong with my project?". Not including type errors was surprising, and with no clear way to show type errors, led to frustration.

Mention any other details that might be useful (optional)

The Architect error wasn't particularly helpful when I ran ng lint --type-check. For one, I didn't know what Architect was, and the error could have offered an alternative command, e.g. ng lint myproject [args].
