asp.net - can some one help me with c# exception? -

i using hellosign c# api , when calling function 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 getting below error.

error    2    'await' operator can used within async method. consider marking method 'async' modifier , changing return type 'task'. 

below getasync method

public async task<account> getasync()         {             accountwrapper accountwrapper = await hellosignservice.makerequestasync<accountwrapper>(settings.hellosignsettings.endpoints.account.get);             return accountwrapper.account;         } 

this type of account class

public class account : accountcondensedwithrole     {         [jsonproperty("callback_url")]         public string callbackurl { get; internal set; }     } 

can 1 tell me how call or how debug ???

you should wrap block in async method

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;  }
