Telerik Login

Hello Ken,

This sponds like you keep attempting to connect to the Telerik NuGet server, but do not have those credentials stored. This is why you're asked for credentials every time and is unrelated to anything you installed locally, it's just how private NuGet servers work.

If you did not save the package source to your machine, then every time a project opens that needs to connect to that source, Visual Studio (or dotnet CLI) is going to ask for credentials again.

Solution

The fastest and easiest way to handle this is to add a nuget.config file to the project, or to update the nuget.config file on your PC. I have a blog post that explains everything => https://www.telerik.com/blogs/azure-devops-and-telerik-nuget-packages 

Side note: If you created your Telerik.com account using a Google OAuth login, you'll need to use a Telerik NuGet Key to authenticate with the nuget server (instead of your username and password). I also have a blog post that explains this, along wth several examples => https://www.telerik.com/blogs/announcing-nuget-keys.

Next Steps

For live demos that use the private nuget server along with a wide range of project types, you can visit my demos here => https://github.com/LanceMcCarthy/DevOpsExamples where you can see my live nuget.config file.
