PnP Core Component - Check if group exists in SharePoint 2016

Please refer to the Introduction to PnP Core Component and OfficeDevPnP.Core for more details. I have created a console application and added SharePointPnPCore2016 NuGet package for the SharePoint 2016 version.

Code Snippet:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using OfficeDevPnP.Core;
namespace SP2016PnPCoreComponentDemo
{
class Program
{
static void Main(string[] args)
{
// Input Parameters
string siteUrl = "http://c7395723754/";
string userName = "administrator";
string password = "Mf165Nz2WV";
string domain = "AD2012";
string groupName = "Group created using PnP";
OfficeDevPnP.Core.AuthenticationManager authMgr = new OfficeDevPnP.Core.AuthenticationManager();
try
{
// Get the client context
using (var ctx = authMgr.GetNetworkCredentialAuthenticatedContext(siteUrl, userName, password, domain))
{
// Check if group exists
if (ctx.Web.GroupExists(groupName))
{
Console.WriteLine(groupName + " exists in the site");
Console.ReadLine();
}
}
}
catch (Exception ex)
{
Console.WriteLine("Error Message: " + ex.Message);
}
}
}
}
