Upgrading from 1.x to 2.0
|
||
|
|
-------------------------
|
||
|
|
Please see http://go.microsoft.com/fwlink/?LinkId=320578 for more information on how to
|
||
|
|
upgrade your SignalR 1.x application to 2.0.
|

|
|
Mapping the Hubs connection
|
||
|
|
----------------------------
|
||
|
|
To enable SignalR in your application, create a class called Startup with the following:
|
||
|
|
|
||
|
|
using Microsoft.Owin;
|
||
|
|
using Owin;
|
||
|
|
using MyWebApplication;
|
||
|
|
|
||
|
|
namespace MyWebApplication
|
||
|
|
{
|
||
|
|
public class Startup
|
||
|
|
{
|
||
|
|
public void Configuration(IAppBuilder app)
|
||
|
|
{
|
||
|
|
app.MapSignalR();
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
Getting Started
|
||
|
|
---------------
|
||
|
|
See http://www.asp.net/signalr/overview/getting-started for more information on how to get started.

Why does ~/signalr/hubs return 404 or Why do I get a JavaScript error: 'myhub is undefined'?
|
||
|
|
--------------------------------------------------------------------------------------------
|
||
|
|
This issue is generally due to a missing or invalid script reference to the auto-generated Hub JavaScript proxy at '~/signalr/hubs'.
|
||
|
|
Please make sure that the Hub route is registered before any other routes in your application.
|
||
|
|
|
||
|
|
In ASP.NET MVC 4 you can do the following:
|
||
|
|
|
||
|
|
<script src="~/signalr/hubs"></script>
|
||
|
|
|
||
|
|
If you're writing an ASP.NET MVC 3 application, make sure that you are using Url.Content for your script references:
|
||
|
|
|
||
|
|
<script src="@Url.Content("~/signalr/hubs")"></script>
|
||
|
|
|
||
|
|
If you're writing a regular ASP.NET application use ResolveClientUrl for your script references or register them via the ScriptManager
|
||
|
|
using a app root relative path (starting with a '~/'):
|
||
|
|
|
||
|
|
<script src='<%: ResolveClientUrl("~/signalr/hubs") %>'></script>
|
||
|
|
|
||
|
|
If the above still doesn't work, you may have an issue with routing and extensionless URLs. To fix this, ensure you have the latest
|
||
|
|
patches installed for IIS and ASP.NET.
