### Microsoft.AspNet.SignalR Simple Usage Example in WebForms To demonstrate a basic use case of `Microsoft.AspNet.SignalR` within an ASP.NET WebForms application, consider implementing real-time chat functionality. #### Server-Side Implementation Firstly, install the SignalR NuGet package through Package Manager Console or via Manage NuGet Packages option in Visual Studio[^1]. Next, create a Hub class named ChatHub.cs: ```csharp using Microsoft.AspNet.SignalR; public class ChatHub : Hub { public void Send(string name, string message) { Clients.All.broadcastMessage(name, message); } } ``` Ensure that OWIN startup configuration is set up properly by adding Startup.cs file to your project and configuring it as follows: ```csharp using Microsoft.Owin; using Owin; [assembly: OwinStartup(typeof(YourNamespace.Startup))] namespace YourNamespace { public class Startup { public void Configuration(IAppBuilder app) { app.MapSignalR(); } } } ``` #### Client-Side Implementation On the client side, include necessary JavaScript files for jQuery and SignalR hub proxy generation at the bottom of Default.aspx page before closing body tag: ```html <script src="Scripts/jquery-3.6.0.min.js"></script> <script src="Scripts/jquery.signalR-2.4.2.min.js"></script> <script src="/signalr/hubs"></script> <script type="text/javascript"> $(function () { var chat = $.connection.chatHub; chat.client.broadcastMessage = function (name, message) { $('#discussion').append('<li><strong>' + htmlEncode(name) + '</strong>: ' + htmlEncode(message) + '</li>'); }; $("#broadcast").click(function () { chat.server.send($('#displayname').val(), $('#message').val()); $('#message').val('').focus(); }); $.connection.hub.start().done(function(){ $('#displayname').focus(); }); }); function htmlEncode(value) { var encodedValue = $('<div />').text(value).html(); return encodedValue; } </script> ``` Add HTML elements like textboxes and buttons on the same page where users can enter their display names along with messages they wish to send across other connected clients instantly without requiring any postbacks. This setup allows multiple visitors viewing this webpage simultaneously experience near-instantaneous updates when someone sends out new information over the network connection established between server and browser instances participating in such conversations[^3]. --related questions-- 1.
