Microsoft.Web.WebView2.WinForms.WebView2 not loading view for second copy of the same application-CodePudding

The

CodePudding user response：

I got this application to work in multi user mode by making the following changes.

I removed initialization of webView.Source property

I added a method which is preparing the environment for each user and explicitly trigger the initialization of webView control. (I'm calling this method inside of MainForm

private async Task InitAsync(string path) { var env = await Microsoft.Web.WebView2.Core.CoreWebView2Environment.CreateAsync(userDataFolder: path); await webView.EnsureCoreWebView2Async(env); }

I set up path param for the user data folder in a next way

path = Path.Combine(Path.GetTempPath(), $"{Environment.UserName}");

I binded navigation path to the target URL in against CoreWebView2InitializationCompleted event handler.

private void webView_CoreWebView2InitializationCompleted(object sender, Microsoft.Web.WebView2.Core.CoreWebView2InitializationCompletedEventArgs e) { if (webView != null && webView.CoreWebView2 != null) { webView.CoreWebView2.Navigate(_baseUrl); } }

All the steps above solved my issus, which was occuring because each new instance of the app for a new user requred environment folder to deal with webView component. Hope that will save some time for somebody.
