使用 Miracast 以编程方式在 Windows 上添加无线显示器

Question

I am looking to develop a WPF application, if not UWP app, that will programmatically add a specific device (a Samsung Tablet) as a wireless display device for Win10. Eg. I have only 1 screen now, I want to add the tablet as my Screen 2 (extend my current Desktop).

It is basically what the 'Win key + K' does, minus the device selection part. Both the Win 10 system and the tablet will be on the same Wifi network.

I have checked out the following samples from Windows UWP samples.

https://github.com/microsoft/Windows-universal-samples/tree/main/Samples/BasicMediaCasting https://github.com/Microsoft/Windows-universal-samples/tree/main/Samples/AdvancedCasting https://github.com/microsoft/Windows-universal-samples/tree/main/Samples/Projection

Using 'Win + K', or using 'add a wireless display' option from Display Settings I am able to find the tablet and connect to it, and enable UIBC, so that I can use the tablet stylus to work on tablet for Windows program such as Whiteboard.

With BasicMedia Casting and AdvanceCasting samples, I am either unable to find the tablet device, or find the device with a 'Phone' icon/category in front. (For 'Win +K' option, the tablet is showed as a 'display' category. ) And I am unable to connect to the tablet with the 2 samples.

With Projection sample, I am able to find and connect to the tablet, but no way to enable UIBC. In addition, Project sample projects a particular application to the tablet, not showing a desktop, although I find out that it does add the tablet as a 2nd screen.

May I know if there is any sample that is suitable for me? Or can point me to any documentation on this topic? And how to enable UIBC programmatically in Windows?

TIA

Programmatically add a wireless display on Windows using Miracast

I have to say, wireless display is system level, there no such api could manage it within UWP platform. BasicMedia Casting is used to cast the media for SMTC, and the receive device need to support casting.

Projection sample shows how to display two different views of your app UI on different screens, as users might do when projecting your app in a meeting or conference.
