Clear the local NuGet caches to ensure no cached Telerik packages exist (it is important in the steps later where your credentials will be stored by Windows). You can run dotnet nuget locals all --clear in your CLI.
Open Visual Studio and go to Tools > NuGet Package Manager > Package Manager Settings > Package Sources.
Click the + button at the top right hand side.
Add the Telerik Feed URL
https://nuget.telerik.com/v3/index.json and choose a Name for that package source (such as "TelerikOnlineFeed").
Click OK and close all Visual Studio instances.
Open a project that has a Telerik UI components library package referenced. For example, generate one through our New Project Wizard.
Make sure to remove local nuget.config files from the solution that contain information about Telerik packages.
From the Build menu select Rebuild Solution.
There will be a Windows prompt asking for credentials for the Telerik feed. Enter the email and password you use to log in to telerik.com.
Make sure to select the Remember my password checkbox.
Your project should now build and restore all packages - including those from nuget.org and from Telerik.
If you experience issues, see the NuGet Feed Troubleshooting article.
The following video explains how you can add the Telerik NuGet feed. If you prefer to do this yourself, follow the rest of this article.
