Downloading a NuGet Package

You can download a .nupkg file to build a private feed for your company by following the steps below.

Such a feed must be private (i.e., not available to the general Internet) and the standard developer-seat licensing model applies (i.e., the developers working with the controls must have active licenses). If you have questions on the licensing scheme, send them to

  1. Navigate to Your Account.

  2. Go to the Downloads page of UI for ASP.NET AJAX.

  3. Click on the .nupkg files you require (e.g., Telerik.UI.for.AspNet.Ajax.Net45.2016.3.1027.nupkg) to download them. The file name is built in the following format: Telerik.UI.for.AspNet.Ajax.Net<.NET version of your project>.<Telerik controls version>.nupkg.

  4. Configure your server and projects to use the feed.

Automated Builds

If you are using the Telerik NuGet feed on an automated build environment, you can provide your own credentials to the build PC so that it can connect to the feed and download the package.

You can read more about adding credentials via the NuGet.config in the following page:

You must protect your credentials and ensure they are used only by you and not by other developers, according to the license-per-developer policy. For example, take your encrypted password from your local NuGet.config file and use it on the build PC.


In R1 2018, the nuget.exe version we use was updated from 2.8 to 4.3. This is the executable file used to generate and read the .nupkg files.

Due to this update, you may get the error below when using Visual Studio 2012 that uses the NuGet Package Manager version 2.0. The solution is to upgrade the NuGet Package Manager to version 2.8.

The schema version of '<namespace>' is incompatible with version 2.0.30625.9003 of NuGet. Please upgrade NuGet to the latest version.
