Navigate to the Central Administration. Click on Application Management. Click on Manage service applications which is available under Service Applications. Click on MMS (Managed Metadata Service). Expand MMS termstore in the Taxonomy Term Store where all the groups for that particular termstore will be displayed. I have a group called “SP2013” which has the following term sets

Ø Apps

Ø BCS

Ø MMS

Ø WAS

Ø NewTermSet

I am going to delete the term set named “NewTermSet” from the taxonomy group “SP2013”. In this blog you will see how to delete the term set from the specified group using Client Object Model.

Steps Involved:

1. Open Visual Studio 2012 (Run as administrator).

2. Go to File=> New => Project.

3. Select Console Application in the Visual C# node from the installed templates.

4. Enter the Name and click on Ok.

5. In the solution explorer, right click on References folder and then click on Add Reference.

6. Add the following assemblies from 15 hive (C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI).

a. Microsoft.SharePoint.Client.dll

b. Microsoft.SharePoint.Client.Runtime.dll

c. Microsoft.SharePoint.Client.Taxonomy.dll

7. Open Program.cs file and replace the code with the following

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Taxonomy;
using System.Collections.ObjectModel;
 
namespace ManagedMetadataClient
{
    class Program
    {
        static void Main(string[] args)
        {
            // ClienContext - Get the context for the SharePoint Site 
            // SharePoint site URL - http://c4968397007/
            ClientContext clientContext = new ClientContext("http://c4968397007/");
 
            // Get the TaxonomySession
            TaxonomySession taxonomySession = TaxonomySession.GetTaxonomySession(clientContext);
 
            // Get the term store by name
            TermStore termStore = taxonomySession.TermStores.GetByName("MMS");            
 
            // Get the term group by Name
            TermGroup termGroup = termStore.Groups.GetByName("SP2013");
 
            // Get the term set by Name
            TermSet termSet = termGroup.TermSets.GetByName("NewTermSet");
 
            // Delete the term set
            termSet.DeleteObject();
 
            // Execute the query to the server
            clientContext.ExecuteQuery();
        }
    }}
