This blog post is aiming at developers that are looking for a solution to deploy SharePoint artifacts from code. Sure, you can do all of this by hand via the SharePoint user interface, but that is not repeatable.
In SharePoint 2007 the recommended solution was to use the feature framework. However, that had (and still has) one big disadvantage: It is hard to upgrade existing sites. FeatureUpgradeActions were introduced in SharePoint 2010, but it is still a manual job.
In 2016, the feature framework has been deprecated in favor of using CSOM / SSOM. I’m going to look at the framework we are using for most of our SharePoint projects to make this a breeze: SPMeta2.
