What type of editor in your c# snippet and what c# project are you using?
Will snippet below work?

        private async void button1_Click(object sender, EventArgs e)
        {

            string result = await webView.CoreWebView2.ExecuteScriptAsync("foo();");
            MessageBox.Show(result);

        }

Hi,@ Harry Potter. How do you add ACE editor to WebView2? What are the steps? And what is the definition of editor in your code?

in order to add ACE editor to WebView2 you have to make index.html and add ace.js they can be found in their repository and of course you can add more javascript files if you want to change theme language mode etc. definition of editor is web browser. index.html = https://github.com/ajaxorg/ace-builds/blob/master/editor.html ace.js = https://github.com/ajaxorg/ace-builds/tree/master/src-noconflicti cant add direct link as it wont let me do that all you gotta do find ace.js and copy all code and paste it into ur ace.js file

            for (int i = 0; i < parameters.Length; i++)
            {
                script += JsonConvert.SerializeObject(parameters[i]);
                if (i < parameters.Length - 1)
                {
                    script += ",";

            script += ");";
            return await webView2.ExecuteScriptAsync(script);
