Please see Private network services sample. It demonstrates how to connect an Azure Sphere device to a private network and use network services.
The AzureIoT sample contains instructions and code for adding web proxy support
Let me know if if that helps or need any further help.

I'm not sure about the Private network services sample, because I want to send some string using WebSocket to a server with local IP. I didn't found such section in that demo.I have tried to connect with
connect(socketFd, (struct sockaddr*)&serverAddress, sizeof(serverAddress)) != 0But I always got
Error connecting to server: Operation timed out (110)I think the connect function is in the
C:\Program Files (x86)\Microsoft Azure Sphere SDK\Sysroots\15\usr\include\sys\socket.hI'm not sure if this is the correct way to use it. Is there any sample for using socket.h to sent and receive WebSocket string message to an Local IP connected using "eth0" (Ethernet Adapter ENC28J60). -

Thank you for your comment.
Do you have any steps or example about how to implement libwebsockets to azuresphere code?

How to implement libwebsockets to AzureSphere? I have tried, but the libwebsockets seems use lots of unix header, that will cause lots of error.
Is there any experience or any way to use websocket on AzureSphere?
