Assembly: Meziantou.Framework.WebPlatform.dll
Package: Meziantou.Framework.WebPlatform 1.0.10

The source of the posture of the device (https://w3c.github.io/device-posture/#dfn-calculate-the-device-posture-information), read by the documents of the browsing contexts that share a BrowsingContextOptions (DevicePostureOptions.Provider). The default implementation returns DevicePostureProvider.Posture, set by the application. Override DevicePostureProvider.GetPosture to read another source, and call DevicePostureProvider.OnPostureChanged when the posture changes, to update the documents.

public class DevicePostureProvider

Remarks

A provider can be shared by several browsing contexts, and used from any thread.
