'await' operator can only be used within an async method with c# exception?

I am using hellosign c# api and when I am calling function for account info using below code 

var helloSign = new HelloSignClient("username", "password");
    Account account = await helloSign.Account.GetAsync();
    Console.WriteLine("Your current callback: " + account.CallbackUrl);

I am getting below error. 

Error    2    The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'.

below is GetAsync method 

public async Task<Account> GetAsync()
        {
            AccountWrapper accountWrapper = await helloSignService.MakeRequestAsync<AccountWrapper>(settings.HelloSignSettings.Endpoints.Account.Get);
            return accountWrapper.Account;
        }

this is type of account class

public class Account : AccountCondensedWithRole
    {
        [JsonProperty("callback_url")]
        public string CallbackUrl { get; internal set; }
    }

Can some one tell me how to call this or how to debug this ???

you should wrap this block in Async Method like this 

public async Task<Type> MethodAsync(){
    // other code if needed ....
    var helloSign = new HelloSignClient("username", "password");
    Account account = await helloSign.Account.GetAsync();
    Console.WriteLine("Your current callback: " + account.CallbackUrl);
    return type;

}

The message is pretty clear. This line must be inside a method marked with async:

Account account = await helloSign.Account.GetAsync();

You can only use await in an async method.
