This is a cleaner way of doing things, and will run Next it shows how to use WinRT device-enumeration APIs, rather than implementing SSDP manually.Next it shows where you can use HttpClient and VB's XML-literals, for a higher-level abstraction rather than doing raw TCP programming.NET45 machine but not allowed on app store) and WinRT code (runs on Windows tablets,Īllowed on app-store, requires Windows8). Next it shows code that implements those raw UDP and TCP communications explicitly, both for device-discovery (SSDP) and for device control (UPnP).The article describes the raw UPnP protocols, i.e., the UDP and TCP messages involved between devices.I wanted to learn about UPnP. More generally, the code might help you understand the UPnP underpinnings of how things work under the hood when you use PlayTo. I wrote this code because my device doesn't yet have windows-8-certified drivers, and because UPNP.dll dating back to XP, but it isn't allowed for app-store apps). (Note that certified drivers are only needed for app-store apps they're not needed for desktop apps. There's also one older technique, using a COM library called To use the Devices charm to make your app stream its video or audio to their TV or speakers or picture-frames, so long as the device's manufacturer has provided Users of your app-store app will then be able PlayTo is far simpler, better-tested, and preferable to implementing all this UPnP stuff yourself. Instead of following this article, there's a key alternative technique that's better - using the new Windows 8 supportįor " Play To" (this link goes to Windows SDK sample code for the PlayTo contract+API). This code plays audio on UPnP speakers. If you have DLNA speakers ("Digital Lifestyle Networking Alliance") they are based on UPnP and it will also work on them.
