Enable Ratings/Likes on List with CSOM

Summary

This sample lets you enable Social features like Rating/Likes on the List/Library. The dependency is on Publishing Feature. At the time of writing there is no method avaiable on Client SDK for .NET to set the Rating Functionality. The implementation is a result of reverse engineering of Server Side Object Model.

//  provide the clientcontext of target web 

var ratingEnabler = new RatingsEnabler(clientContext);


//  1. Library name as per locale
//  2. Experience Ratings/Likes

ratingEnabler.Enable("**ListNameHere**", VotingExperience.Ratings);

Steps Performed:

1. Validate if current web is publishing web, else skip processing.
2. Find List/library
3. Add property to RootFolder of List/Library: key: Ratings_VotingExperience value: Likes/Ratings
4. Add Ratings & Likes fields to List/Library
