ICoreWebView2EnvironmentOptions Language

Hello ,

how can change the ICoreWebView2EnvironmentOptions.Languge without recreate the webView

i try this but not work [DelphiCode]

var aEnvironment         : ICoreWebView2Environment;
    aEnvironmentOptions  : ICoreWebView2EnvironmentOptions;
    HR                   : HRESULT;
begin
  {
    aEnvironmentOptions not exist function to get this interface and change language ???

    Does the whole webView need to be recreated?

    ??? ???? ???
  }
  if Not WebViewCreated then exit;
  if Not LastWebViewIsValid then exit;
  // Get Environment from WebView
  aEnvironment := nil;
  HR           := FLastWebViewSupported.get_Environment(aEnvironment);

  if Assigned(aEnvironment) and ProcessHResultAM(HR)  then
 begin
    //Search interface ICoreWebView2EnvironmentOptions
    aEnvironment.QueryInterface(IID_ICoreWebView2EnvironmentOptions,aEnvironmentOptions)
  end
  else
    DoErrorLog('SetLanguage',Format('get_Environment error %d',[HR]));

  if not Assigned(aEnvironmentOptions) then
  begin
    DoErrorLog('SetLanguage','ICoreWebView2EnvironmentOptions not found');
    exit;
  end;
  // SetLanguage
  HR := aEnvironmentOptions.Set_Language(PChar(ifThen(String(FEdgeLanguage.LanguageISO3166)='',DEFAULT_ISO_3166_VALUE,String(FEdgeLanguage.LanguageISO3166))));

  if not ProcessHResultAM(HR) then
   DoErrorLog('SetLanguage',Format('Set_Language error %d',[HR]));

Thanks

Start with the ICoreWebView2EnvironmentOptions and get_Environment calls shown in the issue, then check the WebView2 API documentation for when Set_Language takes effect. Determine whether changing the language on an existing environment is supported or requires recreating the WebView. Done means documenting the supported behavior and any required lifecycle steps.
