  I must emphasize that I am not a C# programming specialist.  I did locate a C# reference that may be relevant though, where dev.QuerySensors was defined with an index bracket on the end as dev.QuerySensors()[0];

  Thanks MartyG

  //var sensors = dev.QuerySensors();
  var depthSensor = dev.Sensors[0];   // sensors[0];
  var colorSensor = dev.Sensors[1];   //sensors[1];

  Hi MartyG,

  I'm back with some news.
  I'am following your  link and this : librealsense/Window.xaml.cs at master · IntelRealSense/librealsense · GitHub

  Now, my problem is solved.
  I have got an other one, but I have fix it (Frame didn't arrive within 5000). Im few words, be carefull with FPS, image size and your USB port.

  In my case, I connect 4 cameras on an USB-3HUB with optic fiber. I have got a good result with 5fps, 848px*480px.
  
  Thanks a lot for your support!
