Hi,
"signalr/hubs"
There is a script file named hubs that the SignalR library dynamically generates at runningtime. So you could't find it locally.
If you want to see the content of this file, you could type in http://localhost:port/signalr/hubs into your browser to see it.
"this is what I am doing, but I cannot get this simple Hello World running."
I have created a simple demo, which could output 'Hello World'. You could refer to:
Code in MyHub2.cs(right-click the project, select Add | SignalR Hub Class (v2).
public class MyHub2 : Hub { public void Hello(string msg) { Clients.All.sendMessage(msg); } }Code in Startup.cs:(right-click the project, then click Add | OWIN Startup Class.)
public class Startup1 { public void Configuration(IAppBuilder app) { app.MapSignalR(); } }Code in Test.html:
<html> <head> <meta charset="utf-8" /> <title></title> <script src="Scripts/jquery-1.10.2.min.js"></script> <script src="Scripts/jquery.signalR-2.1.2.min.js"></script> <script src="signalr/hubs"></script> </head> <body> <div id="log"></div> <script type="text/javascript"> $(function () { var myHub = $.connection.myHub2;//the hub class name myHub.sendMessage = function (data) { $('#log').html(data); }; $.connection.hub.start({transport: 'auto' }, function () { myHub.sendMessage("Hello World!"); }); }); </script> </body> </html>You could see the result like this:

Hi Yeoman,
Please try to use the following code:
public partial class HowtoexecuteaPowerShellscriptandcontinuouslywritetheoutputtoaTextBox : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btn_Execute_Click(object sender, EventArgs e) { var shell = PowerShell.Create(); shell.Commands.AddScript(txt_Input.Text); var results = shell.Invoke(); if (results.Count > 0) { var builder = new StringBuilder(); foreach (var psObject in results) { // Convert the Base Object to a string and append it to the string builder. // Add \r\n for line breaks builder.Append(psObject.BaseObject.ToString() + "\r\n"); } // Encode the string in HTML (prevent security issue with 'dangerous' caracters like < > txt_Output.Text = txt_Output.Text + Server.HtmlEncode(builder.ToString());//output continuously } } }You could see the result like this:
