Im usisng Masstransit Requst Response in asp.net core when I Send Request before get Response Request Canceling and throw Exception

Question

I am using Masstransit Request-Response in Asp.NetCore When I send Request before I get Response, Request is getting Cancelled and throwing this Exception

System.Threading.Tasks.TaskCanceledException: A task was canceled.

I have downloaded masstransit codes and debugging my project with it. I understand ClientRequestHandle dispose and cancel requests before my response is received.

I checked Consumer side and it works successfully and sends Response as expected.

this is my code: try { using (var handle = _getOrderInfoRequestClient.Create(new GetThirdPersonInsuranceProductAmountCommand(productId))) { var response = await handle.GetResponse>(); if (!response.Message.IsSuccess) throw new DomainException(response.Message.Message); return Convert.ToDecimal(response.Message.ResponseValue.Value); } } catch (Exception ex) { throw; } — hadi nasehi, Feb 16 '19 at 14:46

When using the RequestHandle<T>, you need to maintain a reference to the handle until the request is completed and the response is received (or a timeout or fault occurs).

You can simplify this by using a single line method, of:

var response = await requestClient.GetResponse<T>(request);

If you need to add things to the request, such as headers, etc. then you need to keep the handle around until it's completed.

using(var handle = requestClient.Create(request))
{
    var response = await handle.GetResponse<T>();
}

thanks Chris.but exception thrown after reviving response. – hadi nasehi Feb 16 '19 at 14:28 — hadi nasehi, Feb 16 '19 at 14:28
