Unable to find package UI.for.WinForms.AllControls.Net60. No packages exist with this id in source(s)

[Steven]

Hello

I have Un-installed all Telerik controls, VS2022.

Used ProgressControlPanelSetupA_2022_1_0727_1.exe to reinstall.

Then, Create new project of type 'Telerik UI for Winforms cSharp .Net Core App'

But I am getting

Severity Code Description Project File Line Suppression State
Error NU1101 Unable to find package UI.for.WinForms.AllControls.Net60. No packages exist with this id in source(s): nuget.org. PackageSourceMapping is enabled, the following source(s) were not considered:

ARTesting D:\Development\AngleRing\AngleRingCRM\ARTesting\ARTesting.csproj 1

Please advise

Thank you.

Hi, Steven,
Your question has already been answered in the support thread (1585933) you have opened on the same topic. However, I am posting the answer here as well in order the community to benefit from it.
We kindly ask you to use just one thread for a specific problem to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two or more tickets instead of one. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread. Thank you for your understanding.

You need to add the Telerik package server (https://nuget.telerik.com/v3/index.json) to the Package sources in Visual Studio. The following help article demonstrates a step by step tutorial how to setup the NuGet server and download the package from there:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

How to work if you are offline with an internal business application?

Hi, Brian, 

It is possible to use the manual download option: https://docs.telerik.com/devtools/winforms/visual-studio-integration/install-using-nuget#manually-download-nuget-packages 

Thus, you will need to download the packages first from your Telerik account and then setup the NuGet packages from a local folder as demonstrate din the referred article.
