**Other (e.g. Ionic/Cordova, Node, browser, operating system):**

### How to reproduce these conditions

Forked and cloned the latest version from

https://github.com/angular/angularfire/tree/master/samples/compat

Ran 'ng serve' and got an error:

`The serve command requires to be run in an Angular project, but a project definition could not be found.`

### Expected behavior

Sample code should run.

### Actual behavior

Sample code doesn't run.

Comece no projeto samples/compat e execute `ng serve` a partir do sample clonado para reproduzir o erro de definição de projeto ausente. Inspecione a configuração do projeto Angular e os pontos de entrada relacionados do workspace; considera-se concluído quando o sample compat iniciar com sucesso usando `ng serve`.
