Sorry for bringing this thread back from the dead.
Your example is the only one I could find that has Razor syntax for the signalR grid however there are some issues I am facing:
The link on the main page to open another browser window instead opens a window which says unknown protocol.
The Update/Delete/Create methods do not work with two instances of the browser open. I am using Firefox latest stable version (41).
Please let me know how to fix this as I am attempting to implement signalR via Razor syntax in an app I am working on.
Thanks
