Adapt view of a ListViewWebPart with CSOM.

In a previous post, I explained how we can easily provision a SharePoint site with the client side object model. In this post I will explain how you can change the view of the ListViewWebPart with CSOM.
Probably this is something you want to do all the time because when you add a ListViewWebPart to a page, in the backgound SharePoint will generate a new hidden view in the views collection of the corresponding list.
Unfortunately, this new view isn't a copy of the current default view of the list...

As always, to work fast, I'm using the OfficeAMS extension methods. Since my last post, things have changed for OfficeAMS, as they say themselves: they've grown up.
