How to configure Nuget.config file to use Теlerik Nuget Server within Xamarin app

Environment

Product Version	2019.2.603.1
Product	Telerik UI for Xamarin

Description

Telerik UI for Xamarin Nuget package is hosted on a private server, it is not published in the official NuGet storage. So, when you're building a Xamarin.Forms application with our Xamarin nuget package in AppCenter, you would need to provide the credentials to the Telerik Nuget Server (they are the same as in your Telerik account) inside a Nuget.config file.

The improved Telerik NuGet Server v3 is now available for beta testing at https://nuget.telerik.com/v3/index.json. The new v3 API is faster, lighter, and reduces the number of requests from NuGet clients. You are welcome to try it. For authentication use the same credentials

Solution

You could check how to setup the Nuget.config file in the MSDN topic below: https://docs.microsoft.com/en-us/nuget/reference/nuget-config-file#package-source-sections

The tricky part is that you'd need to use ClearTextPassword field for the credentials.

Here is an example with setting up Telerik Nuget Server in Nuget.config:

<packageSources>
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
    <add key="Telerik" value="https://nuget.telerik.com/nuget" />
</packageSources>
<packageSourceCredentials>
    <Telerik>
      <add key="Username" value="%TELERIK_USERNAME%" />
      <add key="ClearTextPassword" value="%TELERIK_PASSWORD%" />
    </Telerik>
</packageSourceCredentials>

and if you want to use the beta server:

<packageSources>
    <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="%TELERIK_USERNAME%" />
      <add key="ClearTextPassword" value="%TELERIK_PASSWORD%" />
    </Telerik>
</packageSourceCredentials>
