asp.net web api - Calling WebApi from Windows Service -


i trying call following method onstart() method of windows service, windows service starts , stops , throws error.

 static async task runasync()     {             lightspeedcontext<righthireunitofwork> _context;             var client = new httpclient();              _context = new lightspeedcontext<righthireunitofwork>("default");              client.baseaddress = new uri("https://api.xyz.com/");             client.defaultrequestheaders.accept.clear();             client.defaultrequestheaders.tryaddwithoutvalidation(                 "x-smarttoken",                 "1dfaaad541c45031c8b92bfab3ssssssssssb5644c368f3");              var content = new stringcontent("", encoding.utf8,                                 "application/json");             string config = "v1/assessments?status=new";             httpresponsemessage response = null;              try             {                 response = await client.getasync(config);             }             catch (httprequestexception httpex)             {                 // determine error here inspecting httpex.message                      }              if (response.issuccessstatuscode)             {                 listresult lr = await response.content.readasasync<listresult>();                  list<smartrecruiters.assessmentorder> lasmtorders = lr.content;

// other processing here 

            }      }

the onstart method follows:

    protected override void onstart(string[] args)     {         this.writetofile("simple service started {0}");          // need call runasync method here...      }

i tried making onstart async, didn't help. thoughts on how can make call?
