    • WPF Designer: The WPF designer isn't currently supported. Add the WebView2 control in your app by directly modifying the appropriate XAML in a text editor.

0.9.488

Release Date: April 20, 2020

NuGet package for WebView2 SDK 0.9.488

This version of the WebView2 SDK requires Microsoft Edge version 84.0.488.0 or higher.

  • Important

    Announcement: Starting with the upcoming Microsoft Edge version 83, Evergreen WebView2 no longer targets the Stable browser channel. Instead, it targets another set of binaries, branded Evergreen WebView2 Runtime, that you can chain-install through an installer that the WebView2 team is currently developing. See Distribute your app and the WebView2 Runtime.

  • Important

    Announcement: Moving forward, the WebView2 team releases two packages:

    • A Prerelease SDK package containing Experimental APIs (for you to try out), and also APIs that have been promoted to Stable status.
    • A Release SDK package that consists entirely of APIs that have reached Stable status (for your confidence).

    To learn about the differences, see Prerelease and Release SDKs for WebView2.

  • Important

    Breaking Change: In order to ensure the WebView2 API aligns with the Windows API naming conventions, the WebView2 team updated the names of the following interfaces.

  • Important

    Breaking Change: The AddRemoteObject JS proxy methods are also renamed.

    • getLocal is now getLocalProperty.
    • setLocal is now setLocalProperty.
    • getRemote is now getHostProperty.
    • setRemote is now setHostProperty.
    • applyRemote is now applyHostFunction.

  • Important

    Breaking Change: Deprecated CreateCoreWebView2EnvironmentWithDetails and replaced with CreateCoreWebView2EnvironmentWithOptions.

  • Added FrameNavigationCompleted event. Now, when an iframe element completes navigation, an event is run and returns the success of the navigation and the navigation ID.

  • Added ICoreWebView2EnvironmentOptions interface, which can be used to determine the version of the Evergreen WebView2 Runtime targeted by your app.

  • Added IsBuiltInErrorPageEnabled setting. Now, you can choose to turn on or off the built-in error webpage for navigation failure and render process failure.

  • Updated Remote Object Injection to support .NET IDispatch implementations (#113).

  • Updated NewWindowRequested event to handle requests from context menus (#108).

  • Released the first separate WebView2 prerelease package where you can access visual hosting APIs. The WebView2 team updated APISample to include the new experimental APIs.

    • Added ICoreWebView2ExperimentalCompositionController interface, to connect to a composition tree and provide input for the WebView2 control.
    • Added ICoreWebView2ExperimentalPointerInfo, which contains all the information from a 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 the CompositionController 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 to ICoreWebView2 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 separated ICoreWebView2 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 the HistoryChanged event is run. The ContentLoading 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. When AreRemoteObjectsAllowed 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.

  • Important

    Breaking Change: Modified DevToolsProtocolEventReceived behavior. Now, you can create a DevToolsProtocolEventReceiver for a particular DevTools Protocol event and subscribe/unsubscribe to such event using add_DevToolsProtocolEventReceived/remove_DevToolsProtocolEventReceived.

  • Important

    Breaking Change: Changed WebMessageReceivedEventArgs get_WebMessageAsString property to a TryGetWebMessageAsString method.

  • Important

    Breaking Change: Changed AcceleratorKeyPressedEventArgs Handle method to a get_Handled property.

0.8.355

Release Date: December 9, 2019

NuGet package for WebView2 SDK 0.8.355

This version of the WebView2 SDK requires Microsoft Edge version 80.0.355.0 or higher.

  • Released WebView2API Sample, a comprehensive guide of the WebView2 SDK. See API Sample.
  • Added IME support for all languages besides English (#30).
  • Updated the API surface of the WebResourceRequested event in response to bug reports. Simultaneously specifying a filter and an event on creation is now deprecated. 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.

0.8.314

Release Date: October 28, 2019

NuGet package for WebView2 SDK 0.8.314

This version of the WebView2 SDK requires Microsoft Edge version 80.0.314.0 or higher.

Changes

  • Added support for Windows 7, Windows 8, and Windows 8.1. See Supported platforms in Introduction to Microsoft Edge WebView2.

  • Added Visual Studio and Visual Studio Code debug support for WebView2. Now, debug your script in the WebView2 right from your IDE. See How to debug when developing with WebView2 controls.

  • Added Native Object Injection for the running script in WebView2 to access an IDispatch object from the Win32 component of the app and access the properties of the IDispatch object. See AddRemoteObject (#17).

  • Added 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

Release Date: September 10, 2019

NuGet package for WebView2 SDK 0.8.270

This version of the WebView2 SDK requires Microsoft Edge version 78.0.270.0 or higher.

Changes

  • Added DocumentTitleChanged event to indicate document title change (Issue #27).

  • Added GetWebView2BrowserVersionInfo API (Issue #18).

  • Added NewWindowRequested event.

  • Updated CreateWebView2EnvironmentWithDetails function to remove releaseChannelPreference. For more information about the CreateWebView2EnvironmentWithDetails 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 to 1 before launching the app. See Test upcoming APIs and features.

  • Updated the CreateWebView2EnvironmentWithDetails function with logic for selecting userDataFolder when not specified. For more information about the CreateWebView2EnvironmentWithDetails function, see CreateWebView2EnvironmentWithDetails. If you previously used the default userDataFolder location, when you switch to the new SDK the default userDataFolder 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, the CreateWebView2EnvironmentWithDetails function might fail. You can copy the data from the old user data folder to the new directory.
