Bug - Can't Resolve Nuget Reference in Freshly Created Telerik WinForms Core Project
  • I'm using Visual Studio 2022 Community. Running as Admin.
  • I've installed the latest Winforms (Telerik_UI_For_WinForms_2022_1_222_Dev.msi)
  • I open Visual Studio and select to create a Word-like project.
  • The files are all created
  • One nuget reference is present under Dependencies/Packages, but shows as unresolved (UI.for.WinForms.AllControls.Net60 (2022.1.222.0))
  • Using the NuGet Package Manager, there is no Telerik package source present.

So, at this point this seems to be a possible bug. The template project did not setup correctly. I have literally done nothing other than download and install Telerik WinForms today and then try to create this project. This _should_ work or give me instructions of further setup that I have to do manually.

I did try a couple other things, but also failed to get things working.

  • I tried to setup the Telerik Package Source as
  • I was able to see various WinForms packages in the Package Manager, includes the one registered in the project. But VS won't update the project to resolve the package.
  • I uninstalled the nuget package to try reinstalling it, but the re-install failed with the following messages

Restoring packages for C:\DevGit\pws\pws.core\pws.core\pws.core.csproj...

followed by many more "NotFound" messages.

Hi Dess,

Thank you for your detailed reply. I was able to get things working finally with your assistance.

I believe the problem all started because the telerik nuget source was initially missing.

After that I think it may have been mostly me breaking things and then trying to fix them again.

One thing that may have made a difference was that I downloaded the Control Panel and repaired or reinstalled WinForms. I did not initially use the Control Panel.

During that step I believe it asked if I wanted to create some nuget directory. I replied, yes.

I don't know if this made the difference.

It could also have simply been selecting "All" for package source, which I think I was not doing after I started messing around with different nuget sources.

The program compiled and ran.

Thanks for the assistance..

Hello, Steve, 

I am really sorry to hear that you are experiencing any difficulties with the NuGet package restoring after creating a new .Net6 Word-inspired template project. Our package depends on other packages on It may be possible that by adding the Telerik feed it has removed the Microsoft one. In this case it won't be able to install our package because of their dependencies. The second image suggests something similar. 

Following the provided information, I was unable to replicate the problem you are facing. The following screenshots demonstrates the exact steps I performed on my end and what is the observed result:


The UI.for.WinForms.AllControls.Net60 NuGet is successfully restored.

Please make sure that has the following source:

Select the All option in the Package Source:

I would recommend you to have a look at the following help article demonstrating two approaches for managing the Nuget packages:

You can either manually download the NuGet package, or download it from the NuGet server. Please give both approaches a try and see how it would work on your end.

In case you are still experiencing any further difficulties, it would be greatly appreciated if you can provide a sample video demonstrating the exact steps you perform and the behavior you observed. Thank you in advance.

I am looking forward to your reply.
