Telerik NuGet Server

The following steps demonstrate how users can take advantage of Telerik NuGet server in order to include our suite in their solution and/or update to the latest available version.

The credentials needed to access Telerik Nuget server are the same you use to log into your Telerik account.

You will find Nuget packages containing the standard and the lite assemblies - the latter have Lite in their names. Please take a look at the Lite Assemblies topic for more details on the difference between them.

Visual Studio for Windows

The first step is to add the Telerik server to the NuGet package sources. This can be done in the Package Manager Settings from the Tools menu.

In the the Package Sources section users can add new sources.

In the Source field users should fill in the address of the Telerik server (URL: and click the Update button.

The Telerik server is now ready to use. Users can go to their solution and open the solution package manager.

'401 Logon failed' error

If you're receiving this error when connecting to Telerik Nuget Server, you could try to update your NuGet credentials through the Windows Credential Manager. Please follow the steps below:

  1. Close all open Visual Studio instances (this is so that all NuGet package manager tasks are stopped).
  2. Open the "Credential Manager" app on your PC.
  3. Scroll through all the entries until you find any that are for
  4. Once you find that entry, expand it and select "edit".
  5. Make sure the username and password are the same ones you use for your Telerik account and clisk
    1. Use the email address in the place of username
    2. Make sure any special characters are escaped (see Handling Special Characters in Password below)
    3. Click "Save"
  6. Make sure the URL does not have a trailing slash, it must be only

Now you can reopen Visual Studio and access the Telerik NuGet server.

Handling Special Characters in Password

If your password contains a special character, those characters need to be escaped or it may fail authentication resulting in Error 401 login failure from the NuGet server. A common character that needs to be escaped is the ampersand &, but it can be as unique as the section character §. There are two ways to handle this.

  1. Change the password so that it only includes characters that do not need to be escaped
  2. HTML encode the password so the special characters are escaped (e.g. my§uper&P@§§word becomes my§uper&P@§§word).

We strongly discourage entering your password into an online encoder utility, use Powershell instead. Here's one example:

Add-Type -AssemblyName System.Web


Powershell Encoding

Networking Problems

Another common problem is that your machine (PC or DevOps agent) is behind a proxy. To check if you're experiencing a networking issue, open the following URL in your web browser:$filter=IsAbsoluteLatestVersion&searchTerm=%27Xamarin%27&includePrerelease=true&$skip=0&$top=100&semVerLevel=2.0.0.

After you enter your username and password, you should see an XML search result containing a list of all the Telerik.UI.for.Xamarin packages available with your license.
