Based on your error
emulator: Cannot find build properties file: C:\Users\egome\SurfaceDuoEmulator\artifacts\\system\build.prop, please open the pathC:\Users\egome\SurfaceDuoEmulator\artifacts\bin\system, if you have build.prop file, then I find your error's path is wrong, the correct path isC:\Users\egome\SurfaceDuoEmulator\artifacts\bin\system\build.prop, your path is\\.Please uninstall your Surface duo from the control pannel, re-install it. Then open the
Surface duo emulator for visual studio, at this first run, it will be slow.![135851-image.png][1]

2021-10-01T06:33:53.82+00:00 Your install way may have some issue, Please uninstall it, check the Surface Duo emulator prerequisites, resintall it. get the full functionality of Surface Duo emulator, please install Android Emulator 30.0.26 or over.
And check the android SDK path if it is correct.

I succeed and have the emulation running, but now I have an Issue
How can I integrate duo into my VS
Now if I run it, I can see it on my dropdown, but it has no name, it just say build

2021-10-06T08:40:38.09+00:00 Open your Project in Visual Studio, build it, and select <build> (Android 11.0 - API 30) (in the list of Running Devices) and deploy.
Debugging (breakpoints, step into, step over, etc) will all work as usual.
