Installing Telerik UI for ASP.NET Core with NuGet

This article describes how to configure your system for the Telerik NuGet source and then use it to install Telerik UI for ASP.NET Core in your project.

NuGet is a popular .NET package manager. Telerik maintains a private NuGet feed with official Telerik UI for ASP.NET Core releases and service packs. In the Telerik NuGet feed, you will see packages that your account has a license for; trials (active) and commercial (active and expired).

Looking for a complete tutorial? Check out the Getting Started guide that uses NuGet to add Telerik UI to the project.

Setting Up the Telerik NuGet Feed

The Telerik NuGet feed allows you instant access to various Telerik and Kendo packages that you can install in your project. You can access either the latest or older versions of the suites.

Before you can use the Telerik NuGet Feed as a Package source, you must configure your machine by utilizing any of the following methods:

• Use the NuGet Package Manager in Visual Studio.

• Use the Telerik UI for ASP.NET Core trial installer.

• Use the Progress Control Panel application.

• Use NuGet CLI.

• Edit the nuget.config file.

The NuGet v2 server at https://nuget.telerik.com/nuget will be sunset in November 2024.

The new v3 protocol offers faster package searches and restores, improved security, and more reliable infrastructure.

To redirect your feed to the NuGet v3 protocol, all you have to do is to change your NuGet package source URL to https://nuget.telerik.com/v3/index.json.

Setup with the NuGet Package Manager

The following video demonstrates how to add the Telerik NuGet feed through the NuGet Package Manager tool in Visual Studio. Scroll below the video to find the required steps.

To configure the Telerik NuGet feed in Visual Studio:

1. Open Visual Studio.

2. Go to Tools > NuGet Package Manager > Package Manager Settings, select Package Manager Sources, and then click the + button.

3. Enter a Name for the Telerik NuGet feed, for example, telerik.com.

4. In the Source field, enter https://nuget.telerik.com/v3/index.json and click OK.

   

You have successfully added the Telerik NuGet feed as a Package source.

The next steps describe how to authenticate your local NuGet instance and display the available packages:

1. Create a new project or open an existing project.

2. Right-click the solution in the Solution Explorer window.

3. Select Manage NuGet Packages for Solution...

   

4. Select the Telerik NuGet Package source from the drop-down list.

5. Click on the Browse tab to see the available packages.

6. Enter your Telerik credentials in the Windows Authentication dialog.

7. In the Visual Studio Package Manager, you will see all packages that are licensed to your user account.

Setup with the Trial Installer

The UI for ASP.NET Core free trial installer package comes with an option that will automatically configure the Telerik NuGet feed for you. Refer to the NuGet feed setup section in the First Steps article for step-by-step instructions.

Setup with the Progress Control Panel Application

If you have already purchased a commercial Telerik UI license, you can use the Progress Control Panel application to configure the Telerik NuGet. The Control Panel has an option that you can select, and it will configure the Visual Studio Package Manager to use the Telerik NuGet feed.

Refer to the NuGet feed setup section in the First Steps article for step-by-step instructions.

Setup with NuGet CLI

The following video demonstrates how to add the Telerik NuGet feed by using the NuGet CLI or directly editing the nuget.config file. Scroll below the video to find the required steps.

To add the Telerik NuGet feed by using the NuGet CLI:

1. Download the latest NuGet executable.
2. Open a command prompt and change the path to where the nuget.exe was downloaded.

3. Execute the command:

   NuGet Sources Add -Name "telerik.com" -Source "https://nuget.telerik.com/v3/index.json" -UserName "your login email" -Password "your password"
   

   The above command stores a token in the %AppData%\NuGet\NuGet.config file. Your original credentials cannot be obtained from this token.

If you are unable to connect to the feed by using encrypted credentials, try the alternative approach of storing credentials in clear text:

   NuGet Sources Add -Name "telerik.com" -Source "https://nuget.telerik.com/v3/index.json" -UserName "your login email" -Password "your password" -StorePasswordInClearText

If you have already stored a token instead of storing the credentials as clear text, you can update the definition in the %AppData%\NuGet\NuGet.config file by using the following command:

   NuGet Sources Update -Name "telerik.com" -Source "https://nuget.telerik.com/v3/index.json" -UserName "your login email" -Password "your password" -StorePasswordInClearText

Setup with nuget.config

An alternative way to add the Telerik NuGet feed is to directly edit the nuget.config file. For more details about this config file, see Microsoft's dedicated article.

To learn more about how this configuration works, see the Common NuGet Configurations article.

To use a nuget.config file for the Telerik feed, you need to:

1. Ensure you have the relevant config file: %AppData%\NuGet\NuGet.Config. You can create a new one by via the dotnet new command by calling dotnet new nugetconfig.

2. Add the Telerik feed to the nuget.config file, and make sure to use plain-text credentials because the .NET Core NuGet tooling does not fully support encrypted credentials. Here is an example of how your config file can look like:

       <?xml version="1.0" encoding="utf-8"?>
       <configuration>
        <packageSources>
           <!--To inherit the global NuGet package sources remove the <clear/> line below -->
           <clear />
           <add key="nuget" value="https://api.nuget.org/v3/index.json" />
           <add key="telerik" value="https://nuget.telerik.com/v3/index.json" />
        </packageSources>
        <packageSourceCredentials>
           <telerik>
             <add key="Username" value="your telerik account email" />
             <add key="ClearTextPassword" value="your plain text password" />
          </telerik>
        </packageSourceCredentials>
       </configuration>
   

Refer to the Telerik NuGet feed instructional video for more details.

Installing the NuGet Packages

After setting up the Telerik NuGet package source, install the packages either through the Package Manager Dialog or the Package Manager Console.

The NuGet packages allow you to use the Telerik UI Tag Helpers and HTML Helpers in your application. For the UI components to render correctly, you must also provide the required client-side resources.
