POINTER_INFO
. This object is passed to SendPointerInput to inject pointer input into the WebView2. - Added ICoreWebView2ExperimentalCursorChangedEventHandler, which tells the app when the mouse cursor over the WebView2 control should be changed. When mouse is over a text box in the WebView2, the cursor changes from the arrow to the selector. The
cursor
property on theCompositionController
tells the app what the mouse cursor should currently be for the WebView2.
0.9.430
NuGet package for WebView2 SDK 0.9.430
This version of the WebView2 SDK requires Microsoft Edge version 82.0.430.0 or higher.
The WebView2 SDK is the official Win32 C++ Beta version, which incorporates several feature requests from feedback. The WebView2 team tries to limit the number of releases with breaking changes. As general availability approaches, several major breaking changes are incorporated in the Beta release.
-
Important
Breaking Change: As the final release approaches the WebView2 team renamed the prefix
IWebView2WebView
toICoreWebView2
in order to make sure the WebView2 API aligns with the Windows API naming convention. Additionally, in order to leverage the WebView2 SDK from UI frameworks, the WebView2 team separatedICoreWebView2
into ICoreWebView2 and ICoreWebView2Host.ICoreWebView2Host
supports resizing, showing-and-hiding, focusing, and other functionality related to windowing and composition. ICoreWebView2 supports all other WebView2 functionality. To learn more about incorporating the changes, see the WebView2 pull request in the WebView2 APISample project. -
Important
Breaking Change: Split DocumentStateChanged into three components: SourceChanged, ContentLoading, and HistoryChanged. Now, when the source URL changes the
SourceChanged
event is run. When the history state is changed theHistoryChanged
event is run. TheContentLoading
event is run before the initial script when a new document is being loaded. Added support for ARM64 architecture.
Added Soft Input Panel (SIP) support for touch screen devices.
Added support for Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, and Windows Server 2016.
Added NotifyParentWindowPositionChanged for the status bar to follow the window in windowed mode. Also, implement the change in windowless mode in order for accessibility features to work.
Added AreRemoteObjectsAllowed setting to globally control whether a webpage can be accessed by any remote objects. By default,
AreRemoteObjectsAllowed
is turned on, so remote objects added by AddRemoteObject are accessible from the webpage. WhenAreRemoteObjectsAllowed
is turned off, the objects aren't accessible from the webpage. Changes are applied on the next navigation event.Added IsZoomControlEnabled setting to prevent users from impacting the zoom of the WebView2 control using Ctrl++ and Ctrl+- (or Ctrl+ mouse wheel). Zoom can still be set using put_ZoomFactor when the setting is turned off.
Changed ZoomFactor to only apply to the current WebView2 control. Zoom changes to the current WebView2 control don't affect other WebViews that you navigated to using the same site of origin. See get_ZoomFactor.
Hid ZoomView UI for WebView2 control (#95).
Added SetBoundsAndZoomFactor. Now, you can set the zoom factor and bounds of a WebView2 control at the same time.
Added WindowCloseRequested event. See add_WindowCloseRequested (#119).
Added support for the
beforeunload
dialog type for JavaScript dialog events and added CORE_WEBVIEW2_SCRIPT_DIALOG_KIND_BEFOREUNLOAD enum entry.Added GetHeaders to HttpRequestHeaders, GetHeader to HttpResponseHeaders, and get_HasCurrentHeader property to HttpHeadersCollectionIterator.

To create a web resource requested event, use add_WebResourceRequested to add the event and AddWebResourceRequestedFilter to add a filter. RemoveWebResourceRequestedFilter removes the filter (#36) (#74). -
Important
Breaking Change: Modified fullscreen behavior. Deprecated IsFullScreenAllowed. Now, by default, if an element in a WebView2 control (such as a video) is set to full screen, it fills the bounds of the WebView2 control. Use the ContainsFullScreenElementChanged event and get_ContainsFullScreenElement to specify how the app should resize the WebView2 control if an element wants to enter fullscreen mode.

AcceleratorKeyPressed
event. See add_AcceleratorKeyPressed (#57).Turned off the
Context Menus
. See put_AreDefaultContextMenusEnabled (#57).Updated
DPI Awareness
. Now, the DPI awareness of the WebView2 control is the same as the DPI awareness of the host app.Note
If another hybrid app is launched with a different DPI Awareness than the original WebView2 control instance, the new WebView2 control instance isn't launched if the
user data folder
is the same (#1).Updated
Notification Change Behavior
so WebView2 automatically rejects notification permission requests prompted by web content hosted in the WebView2 control.
0.8.270

event.Updated
CreateWebView2EnvironmentWithDetails
function to removereleaseChannelPreference
. For more information about theCreateWebView2EnvironmentWithDetails
function, see CreateWebView2EnvironmentWithDetails. The registry and environment variable override is still supported. The default channel preference is used unless overridden.During the channel search, the WebView2 team skips any previous channel version that isn't compatible with the WebView2 SDK.
The WebView2 team selects the more stable channel to ensure the most consistent behaviors for the end user. When you test with the latest Canary build, you should create a script to set the
WEBVIEW2_RELEASE_CHANNEL_PREFERENCE
environment variable to1
before launching the app. See Test upcoming APIs and features.Updated the
CreateWebView2EnvironmentWithDetails
function with logic for selectinguserDataFolder
when not specified. For more information about theCreateWebView2EnvironmentWithDetails
function, see CreateWebView2EnvironmentWithDetails. If you previously used the defaultuserDataFolder
location, when you switch to the new SDK the defaultuserDataFolder
is reset (set to a new location in the host code directory) and your state is also reset. If the host process doesn't have permission to write to the specified directory, theCreateWebView2EnvironmentWithDetails
function might fail. You can copy the data from the olduser data folder
to the new directory.
