Configure Telerik NuGet

Use these helper functions to manage Telerik NuGet source configuration.

Get a new api key at https://www.telerik.com/account/downloads/api-keys

Function: configure#

Sets a global user environment variable for the Telerik API key and updates/creates nuget.config so credentials use the environment variable instead of a hardcoded secret.
