NuGet is a package manager primarily used for packaging and distributing software written using the .NET framework. A NuGet package is a single ZIP file that contains .NET assemblies and their needed files, with a manifest file describing its contents. Developers may create these packages with the NuGet client app and publish them in private or public repositories. NuGet enables developers to create, share, and consume useful .NET libraries. The NuGet Gallery is the central package repository used by all package authors and consumers. The ability to easily build on the work of others is one of the most powerful features of a package management system, and much of what NuGet does is managing that dependency tree or "graph" on behalf of a project.
