using System;
using Xero.Api.Core;
using Xero.Api.Example.Applications.Partner;
using Xero.Api.Example.Applications.Public;
using Xero.Api.Infrastructure.Interfaces;
using Xero.Api.Infrastructure.OAuth;
using Xero.Api.Example.TokenStores;
using Xero.Api.Serialization;
using System.Configuration;

namespace XeroApplication.Helpers
{
    public class ApplicationSettings
    {
        public string BaseApiUrl { get; set; }
        public Consumer Consumer { get; set; }
        public object Authenticator { get; set; }
        
    }

    public static class XeroApiHelper
    {
        private static ApplicationSettings _applicationSettings;

        static XeroApiHelper()
        {
            // Refer to README.md for details
            //var callbackUrl = "";
            var callbackUrl = ConfigurationManager.AppSettings["callbackUrl"];
            var memoryStore = new MemoryTokenStore();
            var requestTokenStore = new MemoryTokenStore();
            var baseApiUrl = ConfigurationManager.AppSettings["baseApiUrl"];
            //var baseApiUrl = "";

            // Consumer details for Application
            var consumerKey = ConfigurationManager.AppSettings["consumerKey"];
            var consumerSecret = ConfigurationManager.AppSettings["consumerSecret"];

            // Signing certificate details for Partner Applications
            //var signingCertificatePath = @"C:\Dev\your_public_privatekey.pfx";
            //var signingCertificatePassword = "Your_signing_cert_password - leave empty if you didn't set one when creating the cert";

            // Public Application Settings
            var publicConsumer = new Consumer(consumerKey, consumerSecret);

            var publicAuthenticator = new PublicMvcAuthenticator(baseApiUrl, baseApiUrl, callbackUrl, memoryStore, 
                publicConsumer, requestTokenStore);

            var publicApplicationSettings = new ApplicationSettings
                {
                    BaseApiUrl = baseApiUrl,
                    Consumer = publicConsumer,
                    Authenticator = publicAuthenticator
                };
             _applicationSettings = publicApplicationSettings;
        }

        public static ApiUser User()
        {
            return new ApiUser { Name = Environment.MachineName };    
        }

        public static IConsumer Consumer()
        {
            return _applicationSettings.Consumer;
        }

        public static IMvcAuthenticator MvcAuthenticator()
        {
            return (IMvcAuthenticator)_applicationSettings.Authenticator;
        }

        public static IXeroCoreApi CoreApi()
        {
            if (_applicationSettings.Authenticator is IAuthenticator)
            {
                return new XeroCoreApi(_applicationSettings.BaseApiUrl, _applicationSettings.Authenticator as IAuthenticator,
                    _applicationSettings.Consumer, User(), new DefaultMapper(), new DefaultMapper());
            }
           
            return null;
        }
    }
}

Open the HomeController.cs  file and create a new method and add the below code in it.

var api = XeroApiHelper.CoreApi();
List<Xero.Api.Core.Model.Account> GetAccounts =new List<Xero.Api.Core.Model.Account>();
GetAccounts = api.Accounts.Find().ToList();
