  title: Microsoft Windows 10 Geolocation Access and Current Position
  summary: Check location permission, request it when unspecified, and then read the device's current geographic position.
  description: >-
    A permission-aware geolocation flow built on the Windows.Devices.Geolocation
    namespace. The workflow first checks the application's GeolocationAccessStatus
    and branches: when access is already Allowed it reads the position directly,
    and when access is Unspecified it prompts the user via a request before
    reading. Each step inlines its request and documents the response status it
    keys on so the flow can be executed without opening the OpenAPI description.

  summary: Resolve geolocation access then read the current geographic position.

    Checks the current geolocation access status, requests access when it is
    unspecified, and reads the current Geoposition with the requested accuracy.
