What are the platforms supported by the ASP. SIGNALR

SIGNALR supports a variety of server and client configurations. In addition, each mode of transmission has its own requirements, and if some kind of transmission is not supported by the system, SIGNALR can gracefully fail over to other types of transmission.

System Requirements
The SIGNALR server component can be supported by a variety of server configurations. This section describes the supported operating systems. NET Framework, IIS and other components.

Supported server operating systems
SIGNALR server components are supported by the following server and client operating systems.

Windows Server 2012
Windows Server R2
Windows 8
Windows 7
Windows Azure

Note that if you want SIGNALR to use the webcosket, you need a Windows Server 2012 or Windows 8 operating system (WebSocket can also be supported by the Windows Azure Web site, provided that the site is. NET Framework version is 4.5, and websockets is already enabled on the configuration page.

Supported servers. NET Framework version
SignalR 2.0 supports only. Net framework 4.5 and examines recommended updates for increased reliability, compatibility, stability, and performance.

Supported IIS versions of the server
SIGNALR is supported by the following versions of IIS.

1), IIS 8, or IIS 8 Express.
2), IIS 7, and IIS 7.5, require extensionless URLs support.
3), IIS must be running in Integrated mode, and Classic mode is not supported. When IIS is running in Classic mode, using a server to send events can result in a 30-second message delay.
4), the managed application must be running in trust mode.
Note that if you use a client operating system, such as for development (Windows 7 or 8), you should not use the full version of IIS or Cassini. Because the client has a limit of 10 concurrent connections, it is very easy to achieve this limitation because the connection is very short and often re-established. And will not be destroyed immediately after the connection is used. You should use IIS Express.

Also note that if you want SIGNALR to use WebSocket, you must use IIS 8 or IIS 8 Express, the server must use Windows 8, Windows Server 2012, and IIS must have WebSocket enabled. For information about enabling WebSocket in IIS, see IIS 8.0 WebSocket Protocol support.
