Trouble Installing a NuGet Library in .NET: Need Guidance

Good morning, I'm new to this .NET world, and I would like your guidance with this issue that I haven't been able to solve. I'm trying to install a library from NuGet.org, but I can't install it. What solution can I implement or what configuration might I have missed? Thank you.

This same issue has occurred with several libraries. I have created new projects and followed the steps from scratch, but I haven't been able to install libraries.

If you have the Visual Studio, then check if it works in principle on your machine using the Manage NuGet Packages window in case of .NET and .NET Framework projects. (It seems to work).

"Good, it seems that the issue has been resolved. I made some modifications in Visual Studio to the package source. It appears that the URL of the source was incorrect. I found the correct URL in this blog: https://davecallan.com/what-is-the-current-nuget-url-and-how-can-we-reset-it-in-visual-studio/. The URL I configured was: 'https://api.nuget.org/v3/index.json,' and it allowed me to install the libraries I needed in both Visual Studio and Visual Studio Code. I hope to be able to install the others in the other project. Thank you very much to everyone who helped me."
