Thanks! Unfortunately, I updated the entire project's structure to use Angular CLI, so this will be a very difficult merge. @kubk can you branch again from master and re-apply your changes - it will probably take less time

@adamkleingit Sure, in which folder should I put an updated example? Currently there are 2 folders with examples in master:

• https://github.com/mobxjs/mobx-angular/tree/master/example
• https://github.com/mobxjs/mobx-angular/tree/master/projects

@adamkleingit Done, now there is a folder with 3 examples (todo, bank, tictactoe) and a folder with mobx-angular sources (projects/mobx-angular)

[adamkleingit]

@kubk I just removed example, and moved all examples to projects as Angular 9 projects

@adamkleingit I've moved the example to the projects folder.

I changed back to use the top Workspace angular.json, to make everything work the same way, and to have the app take the local mobx-angular and not from node_modules (if it's built)
