NuGetorg

NuGet.org is the official public hosting site for NuGet packages and the central repository used by the .NET ecosystem. It provides a distribution point for libraries, tools, and other packages packaged in the NuGet format (.nupkg). Each package includes metadata such as id, version, authors, description, license, and dependencies, which enables dependency resolution and compatibility checks during installation.

Publishers can upload packages to nuget.org via the NuGet CLI, the dotnet CLI, or the web interface, and they can manage versions, deprecations, and licenses from their account. Consumers browse and search the catalog, install packages into projects, and update dependencies through Visual Studio, the dotnet CLI, or NuGet Package Manager.

NuGet.org also exposes APIs and feeds that enable automation and integration with build systems and package metadata services. It was formerly known as NuGet Gallery and was rebranded as nuget.org as the NuGet ecosystem matured; it has been maintained by Microsoft and the .NET community since the project’s early days.

Key features include package signing and verification support as part of the broader NuGet security model, as well as license information, deprecation notices, and statistics such as download counts and version histories. It is used by many developers to share and reuse code in .NET applications.
