The comments list feature could be added to the system by performing the following steps:

1. Create a repository interface, ICommentRepository.
2. Create a repository object, CommentRepository.

3. Create a query object interface, IGetCommentsByPostQuery.
4. Create a concrete query object, GetCommentsByPostQuery.
5. Configure the CommentRepository injection in the Startup file.
6. Create a View component, CommentsListViewComponent.
7. Create a View, Default.cshtml, under Shared | Components | CommentsList.
8. Include the current library in the _ViewImports.cshtml to support the custom tag helper.
9. Add components using the custom tag helper, <vc:comments>.

The preceding listed implementation is performed and available in the following Git repository commit:
