Starting in Windows 10, version 1803 , the Windows.Graphics.Capture namespace provides APIs to acquire frames from a display or application window.

You could use the GraphicsCapturePicker class to invoke the system picker UI. The end user uses this UI to select the display or application window of which to take screen captures. The picker will return a GraphicsCaptureItem that will be used to create a GraphicsCaptureSession.

Please refer this document that contains complete sample code.
