Microsoft.Web.Webview2 issue

When is the Microsoft.Web.Webview2 issue expected to be resolved? 

Even after adding in the Microsoft.Web.WebView2 1.0.4078.44 nuget dependency to my project, as suggested here: https://feedback.telerik.com/winforms/1714837-radpdfviewer-could-not-load-microsoft-web-webview2-winforms-in-q2-2026, I get a runtime exception because WebView2 is targeting .NET 10 10.0.0.17763.10 and my .NET 10 version is 10.0.201.

Should I downgrade to earlier version of Telerik UI for WPF or is there another workaround?

The Telerik dependencies I'm using are as follows:

Telerik.Windows.Controls.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.Data.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.Diagrams.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.Docking.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.FileDialogs.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.GridView.for.Wpf.Xaml.2026.2.701
Telerik.Windows.Controls.Navigation.for.Wpf.Xaml.2026.2.701

Hello Andrew,

Thank you for reaching out to us.

The reported behavior in this feedback item: RadPDFViewer: Could not load Microsoft.Web.WebView2.WinForms in Q2 2026 is already fixed. In the upper-left corner, the item status is set to Complete. Below the status, it specifies which version of our controls contains the fix. In this case, the 2026.2.702 version. You can download the version from your account. The Download Product Files help article lists the steps to navigate to the download page of your account. 

May I ask you to check this version of our assemblies and let me know if the reported behavior is still observed on your side?

Regards,
