The constructors of the following types now accept the base interface (IWebViewHandler) instead of a specific, concrete type that implements the interface (WebViewHandler):
Microsoft.Maui.Platform.MauiWebChromeClientMicrosoft.Maui.Platform.MauiWebViewNavigationDelegate
Version introduced
.NET 7
Previous behavior
The constructors of MauiWebChromeClient and MauiWebViewNavigationDelegate required the caller to pass in a concrete Microsoft.Maui.Handlers.WebViewHandler instance.
New behavior
The constructors of MauiWebChromeClient and MauiWebViewNavigationDelegate now accept any implementation of the interface Microsoft.Maui.Handlers.IWebViewHandler.
Type of breaking change
This change can affect binary compatibility.
Reason for change
The original constructors required the caller to pass in a concrete type that's not user-controllable and could throw at any point depending on the library author or order of imports. The new implementation just requires the base interface, which is something a developer can actually use.
Recommended action
- If you've overridden the
WKUIDelegatemapper for the iOS or Mac CatalystWebViewHandler, multi-targetnet6.0-iosandnet7.0-iosornet6.0-maccatalystandnet7.0-maccatalyst. - If you've overridden the
WebChromeClientmapper for the AndroidWebViewHandler, multi-targetnet6.0-androidandnet7.0-android. - Otherwise, no action is necessary.
