Whether it's encryption, authentication, state management, or just string utilities, every team has a collection of useful tools that can be reused across projects. Many end up copy/pasting or using a giant monorepo to share this code. By learning to generate Nuget packages and hosting a private Nuget source, your team can quickly add the shared code to any new project, and you can improve these packages iteratively. Learn to pack, publish, and share libraries with Nuget.
