Description:

I recently upgraded my .NET Framework project to .NET Core 8. However, I'm now encountering an issue where the RadListView component is not recognized. I've tried adding the necessary NuGet packages, but the error persists.

The specific error message I'm receiving is:

CS0234: The type or namespace name 'RadListView' does not exist in the namespace 'Telerik WinControls.UI' (are you missing a reference?)

I've attached a screenshot of the error message for your reference.

I'm using the Telerik RadControls for WinForms library, and I've made sure to install the latest version of the NuGet package (Telerik.WinControls.dll). I've also tried adding the following using directives:


using Telerik.WinControls.UI;
using Telerik.WinControls;

But the error persists.

I've searched for similar issues online, but I haven't been able to find a solution that works for me. I'm hoping someone here can help me troubleshoot this problem.

Additional details:

  • I'm using Visual Studio 2022.
  • I'm targeting .NET Core 8.
  • I've tried cleaning and rebuilding the project.

Any help would be greatly appreciated.

Here are some additional things you can include in your forum post:

  • Any relevant code snippets
  • The exact versions of the Telerik RadControls for WinForms library and NuGet package that you're using
  • The steps you took to upgrade your project to .NET Core 8

I hope this helps!

Hi Roberto,

Thank you for reaching out to us and for the shared information. I will assist you with your case.

May I ask you to share the exact name of the added NuGet package in your project? In your case, you should use: UI.for.WinForms.AllControls.Net80

Can you also elaborate if the error appears during design time and you are able to run the project or if the project is not buildable at all? Is it possible to isolate your set-up in a sample project?
