问题 I'm working on a project to front an asynchronous process with a synchronous front-end to make the web call appear as synchronous, and am exploring the use of SignalR to tie it all together. We host a service with a WCF endpoint which is asynchronous, and that works for most of our clients. They send us data, and we process it, without them getting a response after that data is processed. Our environment is multi-tier, and asynchronous by design. There is a need, however, to host a

问题 I'm creating a Hub class for my SignalR server and wanted to use a generic method which will save me from tons of lines of code. But SignalR is giving me errors when I try to Invoke the server code below from a Xamarin.iOS client which also in C#. Server Code public List<T> SendDataToClient<T>() where T : BusinessEntityBase { return SomeDBManager.GetItems<T>(); } Client Code var list = await hubProxy.Invoke<List<Article>>("SendDataToClient"); Am I doing something wrong here or is it just

问题 Why SignalR is making different connection in browser multiple tabs for same logged-in user. Is there any way to make one connection for all tabs opened in same browser. From connection I mean connectionID of a user in SignalR. 回答1: Because different tabs of the same browser are different documents\"processes" - each tab in some sense represents different "instance" of client app. There is no way to share JavaScript objects between them directly (and thats the reason why SignalR opens new

问题 I have just started working with SignalR for realtime update. I need to perform some operation after the connection is established. so I have written that code in .done() method. The issue I am facing is : establishing connection takes some time and due to that I am not able to perform the operation which I am intended to. Following code snippet of my js. $(function () { // Proxy created on the fly projectHub = $.connection.projectHub; $.connection.hub.logging = true; // Start the connection

问题 I've written a small echo-server (.net 4.5), console client (.net 4.5) and web client using SignalR and example presented here. Server is hosted in IIS8/Win8. Then I ran both clients on Win7. and I see that web client in Chrome uses webSockets, while console app client uses serverSentEvents. If I run console client on Win8, then webSockets transport is in use. Is it true that SignalR .NET client will use webSockets only on Win8 and higher? 回答1: It's correct: .NET client uses WebSockets only
