ASP.NET CORE – No @HTML.Action….hello ViewComponents !!!

Child actions are removed from ASP.NET Core MVC i.e. there is no @Html.Action ….instead new feature called ViewComponents is introduced.

Concepts is very similar but implementation approach is bit different. To me, major benefit of it is “separation of concerns”.

It can be basically a combination of – HtmlHelper + Child Actions + Separation of Concern + Asynchronous + Dependency Injection

With partial views or child actions, you have dependency on controller.  ViewComponents do not need controller and are implemented separately

Here is a good article if you want to explore more:

Docker error – No activity detected on VM, aborting

Recently I upgraded docker for windows to latest version 18.06.0-ce-win72 and it started giving below error in visual studio.

No activity detected on VM, aborting

Windows Version: 10
Docker for Windows CE Version: 18.06.0-ce-win72 2018-07-26

Till time issue is fixed,  solutions are:
1. Revert back to last stable version 18.03.1
2. OR Reset to factory settings (option available under Settings menu of Docker for windows)
