Problem when making a discord bot

Question

Hi, so basically, I am trying to make a discord bot but it is not working due to the following line:

 

await CommandService.AddModulesAsync(Assembly.GetEntryAssembly());

 

The error that my compiler prompts is:

 

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)' Discord Bot C:\Users\*********\Desktop\Discord Bot\Discord Bot\Program.cs 37 Active

 

I will leave the code right above here (the line with error is 37):
