Its main purpose is to be set to <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CreationProperties"/> in order to customize the environment and/or controller used by a <see cref="T:Microsoft.Web.WebView2.Wpf.WebView2"/> during implicit initialization. It is also a nice WPF integration utility which allows commonly used environment/controller parameters to be dependency properties and be created and used in markup. </summary> <remarks> This class isn't intended to contain all possible environment or controller customization options. If you need complete control over the environment and/or controller used by a WebView2 control then you'll need to initialize the control explicitly by creating your own environment (with <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2Environment.CreateAsync(System.String,System.String,Microsoft.Web.WebView2.Core.CoreWebView2EnvironmentOptions)"/>) and/or controller options (with <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2Environment.CreateCoreWebView2ControllerOptions"/>) and passing them to <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.EnsureCoreWebView2Async(Microsoft.Web.WebView2.Core.CoreWebView2Environment,Microsoft.Web.WebView2.Core.CoreWebView2ControllerOptions)"/> *before* you set the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.Source"/> property to anything.

As far as I know so far this only occurs before an event loop as started on the running thread. Once there's an event loop running the `SynchronizationContext` ensures that `await`s resume in the same event loop (i.e. same thread). Although it's a rare corner case, it's possible to create a `Window` w/ `WebView2` before an app's event loop starts. This sub-gate handles that corner case. </remarks> </member> <member name="P:Microsoft.Web.WebView2.Wpf.ImplicitInitGate.PendingInitAction"> <summary> An action which will trigger initialization next time the gate is open (and only once). </summary> <remarks> This basically tracks whether or not implicit initialization has been requested while the gate is closed.

You can directly access the underlying ICoreWebView2 interface and all of its functionality by accessing the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> property. Some of the most common COM functionality is also accessible directly through wrapper methods/properties/events on the control. Upon creation, the control's <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> property will be <c>null</c>. This is because creating the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> is an expensive operation which involves things like launching Edge browser processes. There are two ways to cause the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> to be created: <list type="bullet"> <item><description> Call the <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.EnsureCoreWebView2Async(Microsoft.Web.WebView2.Core.CoreWebView2Environment,Microsoft.Web.WebView2.Core.CoreWebView2ControllerOptions)"/> method. This is referred to as explicit initialization. </description></item> <item><description> Set the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.Source"/> property (which could be done from markup, for example). This is referred to as implicit initialization. Either option will start initialization in the background and return back to the caller without waiting for it to finish. To specify options regarding the initialization process, either pass your own <see cref="T:Microsoft.Web.WebView2.Core.CoreWebView2Environment"/> to <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.EnsureCoreWebView2Async(Microsoft.Web.WebView2.Core.CoreWebView2Environment,Microsoft.Web.WebView2.Core.CoreWebView2ControllerOptions)"/> or set the control's <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CreationProperties"/> property prior to initialization. </description></item> </list> When initialization has finished (regardless of how it was triggered or whether it succeeded) then the following things will occur, in this order: <list type="number"> <item><description> The control's <see cref="E:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2InitializationCompleted"/> event will be invoked. If you need to perform one time setup operations on the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> prior to its use then you should do so in a handler for that event. </description></item> <item><description> If initialization was successful and a Uri has been set to the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.Source"/> property then the control will start navigating to it in the background (i.e. these steps will continue without waiting for the navigation to finish). </description></item> <item><description> The Task returned from <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.EnsureCoreWebView2Async(Microsoft.Web.WebView2.Core.CoreWebView2Environment,Microsoft.Web.WebView2.Core.CoreWebView2ControllerOptions)"/> will complete. </description></item> </list> For more details about any of the methods/properties/events involved in the initialization process, see its specific documentation. Because the control's <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> is a very heavyweight object (potentially responsible for multiple running processes and megabytes of disk space) the control implements <see cref="T:System.IDisposable"/> to provide an explicit means to free it. Calling <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.Dispose(System.Boolean)"/> will release the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> and its underlying resources (except any that are also being used by other WebViews), and reset <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> to <c>null</c>. After <see cref="M:Microsoft.Web.WebView2.Wpf.WebView2.Dispose(System.Boolean)"/> has been called the <see cref="P:Microsoft.Web.WebView2.Wpf.WebView2.CoreWebView2"/> cannot be re-initialized, and any attempt to use functionality which requires it will throw an <see cref="T:System.ObjectDisposedException"/>. Accelerator key presses (e.g. Ctrl+P) that occur within the control will fire standard key press events such as OnKeyDown. You can suppress the control's default implementation of an accelerator key press (e.g. printing, in the case of Ctrl+P) by setting the Handled property of its EventArgs to true. Also note that the underlying browser process is blocked while these handlers execute, so: <list type="number"> <item> <description>You should avoid doing a lot of work in these handlers.</description> </item> <item><description> Some of the WebView2 and CoreWebView2 APIs may throw errors if invoked within these handlers due to being unable to communicate with the browser process. </description></item> </list> If you need to do a lot of work and/or invoke WebView2 APIs in response to accelerator keys then consider kicking off a background task or queuing the work for later execution on the UI thread. Note that this control extends <see cref="T:System.Windows.Interop.HwndHost"/> in order to embed windows which live outside of the WPF ecosystem. This has some implications regarding the control's input and output behavior as well as the functionality it "inherits" from <see cref="T:System.Windows.UIElement"/> and <see cref="T:System.Windows.FrameworkElement"/>. See the <see cref="T:System.Windows.Interop.HwndHost"/> and [WPF/Win32 interop](/dotnet/framework/wpf/advanced/wpf-and-win32-interoperation#hwnds-inside-wpf) documentation for more information. </remarks> <seealso cref="T:System.Windows.Interop.HwndHost"/> </member> <member name="M:Microsoft.Web.WebView2.Wpf.WebView2.#ctor"> <summary> Creates a new instance of a WebView2 control.
