Add TermStore Managers and Contributors using CSOM

A new version of CSOM was released today for SharePoint Online. You can find more information about that here: http://dev.office.com/blogs/new-sharepoint-csom-version-released-for-Office-365-may-2016

This version adds the ability to add/retrieve Managers and Contributors to a Term Group in the SharePoint Online Term Store.

Here is a quick code snippet I put together for achieving this:

	ClientContext clientContext = GetClientContext();
	var taxonomySession = TaxonomySession.GetTaxonomySession(clientContext);
	var termStore = taxonomySession.GetDefaultSiteCollectionTermStore();
	var myTermGroup = termStore.Groups.GetByName("My Custom Terms Group");
	//Add Group Managers
	myTermGroup.AddGroupManager("i:0#.f|membership|ccdev2@tenant.onmicrosoft.com");
	//Add Group Contributors
	myTermGroup.AddContributor("i:0#.f|membership|ccdev1@tenant.onmicrosoft.com");
	myTermGroup.AddContributor("i:0#.f|membership|ccdev3@tenant.onmicrosoft.com");
	clientContext.Load(myTermGroup, group => group.GroupManagerPrincipalNames, group => group.ContributorPrincipalNames);
	clientContext.ExecuteQuery();
	Console.WriteLine("Group Managers: ");
	foreach (var manager in myTermGroup.GroupManagerPrincipalNames)
	{
	Console.WriteLine(manager);
	}
	Console.WriteLine("Group Contributors: ");
	foreach (var contributors in myTermGroup.ContributorPrincipalNames)
	{
	Console.WriteLine(contributors);
	}
