About making a Discord Bot

[Smashy77]

I am using C#(Discord.NET CORE) and I faced this kind of error and I don't know how to fix it exactly. it sounds like this:

"Severity Code Description Project File Line Suppression State
Error CS7036 There is no argument given that corresponds to the required formal parameter 'services' of 'CommandService.AddModulesAsync(Assembly, IServiceProvider)' TestBot C:\Users\user\source\repos\TestBot\TestBot\Program.cs 54 Active"


Also, there is full program code:

using Discord;
using Discord.Commands;
using Discord.WebSocket;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Reflection;
using System.Threading.Tasks;
namespace TestBot
{
class Program
{
static void Main(string[] args) => new Program().RunBotAsync().GetAwaiter().GetResult();
private DiscordSocketClient _client;
private CommandService _commands;
private IServiceProvider _services;
public async Task RunBotAsync()
{
_client = new DiscordSocketClient();
_commands = new CommandService();
_services = new ServiceCollection()
.AddSingleton(_client)
.AddSingleton(_commands)
.BuildServiceProvider();
string botToken = "Something...";
//event subscription
_client.Log += Log;
await RegisterCommandsAsync();
await _client.LoginAsync(TokenType.Bot, botToken);
await _client.StartAsync();
await Task.Delay(-1);
}
private Task Log(LogMessage arg)
{
Console.WriteLine(arg);
return Task.CompletedTask;
}
public async Task RegisterCommandsAsync()
{
_client.MessageReceived += HandleCommandAsync;
await _commands.AddModulesAsync(Assembly.GetEntryAssembly());
}
private async Task HandleCommandAsync(SocketMessage arg)
{
var message = arg as SocketUserMessage;
if (message is null || message.Author.IsBot) return;
int argPos = 0;
if (message.HasStringPrefix("gay!", ref argPos) || message.HasMentionPrefix(_client.CurrentUser, ref argPos))
{
var context = new SocketCommandContext(_client, message);

var result = await _commands.ExecuteAsync(context, argPos, _services);
if (!result.IsSuccess)
Console.WriteLine(result.ErrorReason);
}

}
}
}



Would you please help me?
