Websockets is introducing web developers to a whole new world of real-time programming but that isn’t the end of the story. SignalR gives ASP.NET developers the ability to build real-time web apps that work both with and without websockets and with an API so easy to use it almost seems like magic (really). You want scale too? No problem; SignalR scales out with your application. Come and see why web programing will never be the same again.

    the package microsoft.aspnet.signalr.sample seems to be no more available on nuget. Any ideas about where to find it ?

  • User profile image


    I think you need to make sure you have "Include Prerelease" selected in the dropdown and NOT "Stable Only".

    Hi I'm new to signalr. Though I update the project for the sample, when I run and press the OPEN MARKET button, it's not working. Can you please let me know are there any machine configurations to be done for the Signalr?

    Thank you.

    you guys missed the demo of Redis and service bus. how can we use them?

    nuget is fail
    this is true

  • User profile image


    Let me be clear: Nuget is certainly not a fail; you have a misunderstanding about it. The package that you are searching is and this is the old SignalR package. So, it's unlisted now so that it won't appear in searches. 

    What you need to install is the Microsoft.AspNet.SignalR.Sample package which also won't appear in searches because it's a pre-release package:

    In order to install this package through PMC, you need to type the following command:

    Install-Package Microsoft.AspNet.SignalR.Sample -pre

    Hey, this is really awesome..And am really looking forward to develop my first app using SignalR.

    I tried the same MoveShape app which Mr.Edwards has demoed. But no luck, getting some issue like
    "SCRIPT5007: Unable to get value of the property 'client': object is null or undefined".
    Can some one please help me with this.

    @Madhu:You need to write MoveShape with uppercase M Wink

    Was having the same problem: "SCRIPT5007: Unable to get the value of the property 'client': object is null or undefined"

    The solution is to write "moveShape" in the Hubname attribute on the controller

  • User profile image

    its simply awesome session...!!!

  • User profile image

    I did the exact same thing that Damien Edwards demoed for moveshape. But my box does not get dragged. Also, the /signalr/hubs does not work for me. I get a blue squiggly line saying it is not found.

  • User profile image

    Very interesting! Move shape worked perfectly and I was able to add more stuff. But there was no luck for persistent connection. I was able to track the error from the browser
    http://localhost:7696/chat/negotiate?_=1365870613397 was not found 404

  • User profile image

    great stuff, works like charm.

  • User profile image

    Awesome stuff, however it does not have something I want.
    What I want is have two webforms. (1) WebForm1 allows to do dataentry (Name, Address). which does CRUD task which should update straight on WebForm2 which shows on Gridview/Table.
    I want to do above how can I achieve using SignalR any example. This is just a small example, If I can achieve this then I can implement on bigger project.

  • User profile image

    Awesome!!! Real time application, a lot of potential and ideas.
