Migrate to PackageReference with 3 clicks

April 09, 2018

Last year, we introduced the option to make PackageReference the default package management format for managing NuGet dependencies when installing the first NuGet package for a newly created projects. With Visual Studio Version 15.7 Preview 3, we have introduced the capability to migrate existing projects that use the packages.config format to use PackageReference instead. Benefits of using PackageReference include: Ability to manage all project dependencies from one place (the project file). An uncluttered view of top-level dependencies: the project file shows only those NuGet packages you directly installed in the project. Faster package install/update times. Better cache management with a [...]

Deprecating authentication

February 27, 2018

As announced in our NuGet Fall 2017 Roadmap blog post, we are transitioning away from’s home-grown authentication mechanism which will eventually allow us to add support for additional security systems such as two-factor authentication (2-FA). In preparation for this transition, we had already added support for Microsoft accounts (MSA) to sign in to and are now announcing support for Azure Active Directory (AAD) that can be used to sign in to We recommend that all publishers start using either MSA or AAD to manage their accounts as soon as possible. We will ensure a smooth transition [...]

Read more... package publishing workflow – behind the scenes

February 01, 2018

In December 2017, we changed the backend publishing pipeline to introduce a set of validation steps for submitted packages. Our goal is to maintain the same level of experience in terms of the time and effort it would take to publish a package and have it available for download. However, these new validation steps caused a few incidents that resulted in significant delays in the publishing workflow. We wanted to share the reasons why the experience has changed over the last few months and the continuous improvements we have been making since then, based on our learnings. Background When [...]


NuGet Package Signing

September 14, 2017

In our NuGet Fall 2017 Roadmap, we highlighted security as the main area of investment over the next few months. This blog post describes a major part of that roadmap in greater detail – package signing. We started talking about supporting signed packages on a while ago. For example, in 2015 we published a post on Package Signing as well as a related specification from the ASP.NET team, and more recently we described package signing as a part of our future plans in the post on NuGet Package Identity and Trust. We´ve received some great feedback from our various [...]


Changes to service management, and performance improvements in China

September 07, 2017, the package manager for .NET, was purpose-built as a global service with high scale performance regardless of the developer’s location. We are finding that this is not always the case, particularly for developers accessing the service from China, which is the second largest region for .NET developers. They frequently face higher download times resulting in poor restore performance and service outages. We have been actively investigating solutions to this problem. Based on our tests, developers in China should see up to 30x improvement in package download times and on average, a 10x improvement in overall package restore time. The [...]

NuGet Fall 2017 Roadmap

August 09, 2017

Over the past 6 months, the NuGet team has been working hard to ensure the growth of the .NET ecosystem. NuGet has grown significantly during this timeframe: is closing in on 4 billion packages served (up from a billion packages just a year ago), we have enabled new .NET scenarios such as .NET Standard 2.0, and have improved the overall user experience of package authors and consumers using the service. Yet, a lot more remains to be done. Along the way, we made some mistakes that our community has rightfully called us out on. We made changes to the [...]
