New in WebView2 SDK 1.0.2357 Pre-release (Feb 6, 2024)

  • Experimental APIs:
  • Added the Runtime selection feature to support more prerelease testing and flighting scenarios. Developers can specify ReleaseChannels to choose which channels are searched for during environment creation, and ChannelSearchKind to select a search order.
