Release notes for Microsoft Edge WebView2 Prerelease SDK, release date: Apr. 7, 2025.
NuGet package for WebView2 SDK 1.0.3230-prerelease
For full API compatibility, this Prerelease version of the WebView2 SDK requires the WebView2 Runtime that ships with Microsoft Edge version 136.0.3230.0 or later; see Runtime 136.0.3240.44 (May 5, 2025).
Detailed contents:
Promotions to Phase 2 (Stable in Prerelease)
The following APIs have been promoted from Phase 1: Experimental in Prerelease, to Phase 2: Stable in Prerelease, and are included in this Prerelease SDK.
Track navigation history for nested iframes (FrameCreatedEvent API)
The FrameCreatedEvent API supports nested iframes, such as recording the navigation history for a second-level iframe. Without this API, WebView2 only tracks first-level iframes, which are the direct child iframes of the main frame. Using this API, your app can subscribe to the nested iframe creation event, giving the app access to all properties, methods, and events of CoreWebView2Frame for the nested iframe.
Use this API to manage iframe tracking on a page that contains multiple levels of iframes. You can choose to track any of the following:
- Only the main page and first-level iframes (the default behavior).
- A partial WebView2 frames tree with specific iframes of interest.
- The full WebView2 frames tree.
Previous phase: Track navigation history for nested iframes (FrameCreatedEvent API) in Prerelease SDK 1.0.3079-prerelease, for Runtime 134 (Jan. 24, 2025).
