crisbeto dcc8ff4ce7 feat(ivy): throw compilation error when providing undecorated classes (#34460)
Adds a compilation error if the consumer tries to pass in an undecorated class into the `providers` of an `NgModule`, or the `providers`/`viewProviders` arrays of a `Directive`/`Component`.

fake_core is a library designed to expose some of the same symbols as @angular/core, without requiring compilation of the whole of @angular/core. This enables unit tests for the compiler to be written without incurring long rebuilds for every change.

  • @angular/core is compiled with @angular/compiler-cli, and therefore has an implicit dependency on it. Therefore core must be rebuilt if the compiler changes.
  • Tests for the compiler which intend to build code that depends on @angular/core must have a data dependency on @angular/core. Therefore core must be built to run the compiler tests, and thus rebuilt if the compiler changes.

This rebuild cycle is expensive and slow. fake_core avoids this by exposing a subset of the @angular/core API, which enables applications to be built by the ngtsc compiler without needing a full version of core present at compile time.
