I have SignalR Client Hub Connection and call InvokeAsynch method and server receives message in correct way. Then i return response and client hangs on InvokeAsync.
In Asp.Net Signalr (neither core nor abp) this manner works but there was CallAsync method in HubProxy instead InvokeAsync in HubConnection.
Client side:
public async Task<bool> EdytujObszar(int elementId, int obszar)
{
bool res = await Connection.InvokeAsync<bool>(EnumTools.GetDescription(MessageTypeEnum.EdytujObszar), elementId, obszar);
return res;
}
Server side:
public class MyHub : OnlineClientHubBase, ITransientDependency, IMyHub
{
private readonly IHubContext<MyHub> _hubContext;
(...)
public bool EdytujObszar(int elementId, int obszar)
{
bool result;
(some logic)
return result;
}
I would like to receive response from server but InvokeAsync hangs forever. Using On method on client side to subscribe on message does not fulfil my expectations in this scenerio.

Hi,
You should do it like this https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Core/Chat/SignalR/SignalRChatCommunicator.cs#L46. You can check SignalRChatCommunicator.cs in your project.

OK. I opened that page. But it is not anticipated approach. As i wrote:
- Client send message to server and wait for response (or not if is async)
- Server receives message, handle it and send response
- Client must receive message from server and receive method (same which sent) unlocks (or not if is async)
Client must not wait for messages byc subscription approach.

Hi @aprsystem
Couldn't understand the problem, sorry.
If you want to use something works asynchronous, you can use SignalR. If you want something synchronous, you can directly call an AppService method.
