We compiled and ran the Angular app to make sure everything was working so far: `npm install --legacy-peer-deps` and `npm start`.

 * [[Commit]](https://github.com/Xenoage/BlazorInAngularDemo/commit/f5faafa8dc6c0315e795950f46f7b29b4458c970) We created a `HeroEditor` component in Blazor, including a parameter and an event callback. Our goal is to replace the inner part of Angular's `HeroDetailComponent` later.
