Still struggling. I get the error "The type or namespace name 'CoreWebView2InitializationCompleted' does not exist in the namespace 'Microsoft.Web.WebView2' (are you missing an assembly reference?)"
I have
using Microsoft.Web.WebView2.WinForms;
I have downloaded and installed Microsoft.Web.WebView2 v. 1.0.2739.15 from NuGet and the project has references
<Reference Include="Microsoft.Web.WebView2.Core, Version=1.0.2739.15, Culture=neutral, PublicKeyToken=2a8ab48044d2601e, processorArchitecture=MSIL">
<HintPath>..\packages\Microsoft.Web.WebView2.1.0.2739.15\lib\net462\Microsoft.Web.WebView2.Core.dll</HintPath>
</Reference>

What am I misssing?

That all looks fine. Have you tried cleaning the solution? Build | Clean solution

Nice thought but sadly not the answer. Have rebooted and tried other solutions that use mostly the same code but no further forward. The problem arisies consistently on all the versions of the app I have tried.
Will resume picking over my csproj files tomorrow so if you have any more brilliant thoughts happy to hear about them.

What platform are you building for? .Net Core, WPF or WinForms
Mine is WPF based (long story), but I didn't use CoreWebView2InitializationCompleted.
namespace DigiwiseDOM { using Microsoft.Web.WebView2.Core; using System; using System.Threading.Tasks; using System.Web; /// <summary> /// Interaction logic for CloudLogin.xaml /// </summary> public partial class CloudLogin : System.Windows.Window { public CloudLogin(string url) { this.InitializeComponent(); Browser.NavigationCompleted += WebBNavigationCompleted; _ = InitializeBrowser(url); } public string GetOAuthCode() { this.ShowDialog(); // The dialog will close once the user has granted access to MYOB and the OAuth code is in the URL // Extract the oAuth code and return it var uri = Browser.Source; var queryParams = HttpUtility.ParseQueryString(uri.Query); var code = queryParams["code"]; Browser.Dispose(); // Prevented an exception that occcurred on exiting the application if we remove this line return code; } private async Task InitializeBrowser(string url) { var userDataFolder = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\DigiwiseQuickExtract"; var env = await CoreWebView2Environment.CreateAsync(null, userDataFolder); await Browser.EnsureCoreWebView2Async(env); Browser.Source = new UriBuilder(url).Uri; } private void WebBNavigationCompleted(object sender, EventArgs e) { var webB = (Microsoft.Web.WebView2.Wpf.WebView2)sender; // Check if OAuth code has been returned and close dialog if it has var uri = webB.Source.ToString(); if (uri.Contains("code=")) { this.Close(); } } } }
