Organizations on NuGet.org

We are happy to announce support for Organizations on NuGet.org. This will help businesses and open-source projects collaborate on packages using a single nuget.org identity. Why organizations?

NuGet.org package publishing workflow – behind the scenes

In December 2017, we changed the NuGet.org backend publishing pipeline to introduce a set of validation steps for submitted packages.

However, these new validation steps caused a few ...

Changes to NuGet.org service management, and performance improvements in China

NuGet.org, the package manager for .NET, was purpose-built as a global service with high scale performance regardless of the developer’s location.
