When trying to debug my Application according to your manual (https://docs.telerik.com/devtools/winui/getting-started) this error appeared in my Debugging Session:
| Name | Wert | Typ | |
|---|---|---|---|
| ▶ | Exception | {"Error HRESULT E_FAIL has been returned from a call to a COM component."} | System.Exception {System.Runtime.InteropServices.COMException} |
It happens when I'm trying to set the ItemsSource of my DataGrid.
I'm using the same declarations as described in your manuals example of using a DataGrid.
I've configured my environment according to the following specifications:
Visual Studio 16.11.1
Project Reunion 0.8.2
Telerik UI For Win UI 0.4.0 | I'm referring to the Win32-Assembly of Progress Control Panel
Are there any known issues with the current setup of 0.4.0 as described in this link (https://www.telerik.com/forums/is-winui-in-desktop-currently-supported)?

Hello Alexander,
Thank you for the provided details.
I tried to replicate the exception you described following the same steps and settings, however, the created WinUI application runs correctly at my end. Please find it attached to my reply for your reference.
Can you please let me know if you're able to successfully run it on your machine?
If that is not the case, here are two troubleshooting steps I can suggest:
- Try to use the 0.8.1 version of the Project Reunion instead as this is the version on which the Telerik.WinUI.Controls.dll is built.
- Try to manually reference the Telerik.WinUI.Controls.dll in your project rather than use the NuGet package.
- Add the following resource dictionary to your application's MergedDictionaries collection:
<Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" /> <ResourceDictionary Source="ms-appx:///Telerik.WinUI.Controls/Themes/Generic.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources>
Please let me know if any of these approaches resolves the exception at your end. I will be awaiting your reply.
