signalr

问题 I am trying to implement the SignalR into my ASP.Net "WEB SITE PROJECT". (This is an existing application and it is a Web Site Project, and can not be changed over to be a Web Application.) I get the following error when I try to run the SignalR Sample code. (This is the basic stock ticker sample. Just wanting to verify I have everything setup correctly before I start implementing this into my existing code.) Here is the error I get Unhandled exception at line 71, column 5 in http://localhost

问题 I have the following scenario, and I would like to know if there is a solution to achieve such thing: I have a WCF service that is running in a backend server, and it does bulk data processing, like inserting records into DB, and I would like to have this service send a message or notification once a record has done processing to a webpage (ASP.NET Page), where this page should be listening to these messages and display a progress with the finished tasks at real-time. Note: The WCF service is

问题 I understand that SignalR is used to communicate with client browsers using the injected artery script. I have what seems to be a common problem, which is that my browser's network log is filled with entries that look like this: .../arterySignalR/poll?transport=longPolling&connectionToken=... This tells me that SignalR has fallen back to long polling instead of using web sockets. Assuming that we have a browser that supports web sockets, and that browser is running on the localhost, shouldn't

问题 I'm using SignalR to return a complex object graph to my JavaScript client. This object graph has multiple references throughout to the same object, so the JSON that SignalR/Json.NET returns looks a lot like this: { "$id": "57", "Name": "_default", "User": { "$id": "58", "UserTag": "ken", "Sessions": [{ "$id": "59", "SessionId": "0ca7474e-273c-4eb2-a0c1-1eba2f1a711c", "User": { "$ref": "58" }, "Room": { "$ref": "57" } }], }, "Sessions": [{ "$ref": "59" }] } (Of course, a lot more complicated

问题 I know similar question is posted here. I uploaded an app to Google Play Store but it is incompatible with all the devices. The app is actually a SignalR based chat application. Check out this image I am attaching the AndroidManifest.xml file.Any help would be appreciated. <uses-feature android:glEsVersion="0x00020000" android:required="true"/> <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity

问题 I am trying to implement the Cross-domain calls with SignalR 1.0.1 with Chrome (Ver 25.0.1364.172). As I have my UI in one host (localhost:16881) and the 'service' in another host (localhost:16901). I have everything in place as in the topic How to use cross-domain connections (CORS - Access Control Allow Origin) with SignalR add jQuery.support.cors = true; before opening a connection set up $.connection.hub.url = 'http://localhost:16901/signalr';, pointing to your subdomain allow cross

问题 I have a Hub class, which has a long running method, I need to display a progress bar while it's working. I read this article and I think it is possible to use IProgress interface in async methods to send long running operation status. I write a method like this: public async Task<string> GetServerTime(IProgress<int> prog) { await Task.Run(() => { for (int i = 0; i < 10; i++) { prog.Report(i * 10); System.Threading.Thread.Sleep(200); } }); return DateTime.Now.ToString(); } And I try to invoke

问题 I would like to build a winform business solution using SiganlR, but I am not able to install .net 4.0 on the client machine. It looks like SignalR has a mininum requirement of .net 4.0. What is the best way to use SignalR from a winform and .net 3.5. I would like to include the send/receive message functions in the client application. I will be hosting SignalR on IIS on my intranet using .net 4.0 on the server side. Would it be possible to create and API (in .net 3.5) similar to pubnub C#?

On the line connection.Start().Wait(); I get an exception. The following is the sequence of exceptions thrown at that line: The specified registry key does not exist System.IO.IOException 'MessageHub' Hub could not be resolved InvalidOperationException The remote server

问题 I'm trying to get SignalR working in an MVC5 project with individual accounts. The MVC project has by default Owin 2.0.0 and all of the Owin.* components are also 2.0.0. So I used NuGet to get all the SignalR packages, it automatically resolved dependancies and downloaded v 2.0.2. The project throws an error on startup with the following message: Could not load file or assembly 'Microsoft.Owin, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' I also tried upgrading Owin to 2
