1/23/2023 0 Comments Microsoft edge webview2 update![]() ![]() The exact throttling limit can change in the future.Įdge update service can only support one update request at a time globally. To protect accidental abuse of the update service, the implementation throttles the calls of this API to 3 times within 5 minutes in a process. Calling this API repeatedly in a short period of time, will also fail with HRESULT_FROM_WIN32(ERROR_BUSY). There could only be one active UpdateRuntime operation in an app process, calling this API before previous call is completed will fail with HRESULT_FROM_WIN32(ERROR_BUSY). When running a fixed version Edge WebView2 Runtime or non stable channel Edge browser, this API will return HRESULT_FROM_WIN32(ERROR_NOT_SUPPORTED). The UpdateRuntimeAsync() method is only supported for an installed Edge WebView2 Runtime. The latest version can always be queried using the GetAvailableBrowserVersionString(String) API. This will not impact Edge browser installations. Besides the NewBrowserVersionAvailable event, there will be no impact to any currently running WebView2s when the update is installed.Įven though the Edge WebView2 Runtime update is installed for the machine and available to all users, the update will happen silently and not show elevation prompt. There is no guarantee on the order of that event being raised and the completed handler being invoked. This will potentially result in a new version of the Edge WebView2 Runtime being installed and NewBrowserVersionAvailable event being raised.
