So you want to hack on NuGet? These notes will help you get your development environment set up correctly so you can work on NuGet using Visual Studio. The lowest supported version is Visual Studio 2015 with Update 1.

Get and Build the code on Windows

  1. Install Visual Studio 2015.1 and ASP.NET 5
  2. Uninstall the existing NuGet Extension from Visual Studio.

To build NuGet.VisualStudioExtension, execute the following steps:

  1. Add the directory of msbuild 14, e.g. C:\Program Files (x86)\MSBuild\14.0\Bin, to PATH

  2. Download the latest version of NuGet.exe, and add its directory to PATH

  3. Start powershell. Create a directory, cd into that directory

  4. Clone NuGet/NuGet.Client repository

     git clone
  5. Build NuGet

     .\build.ps1 -CleanCache

The generated vsix will be in the artifacts folder

For more details, please visit the NuGet/Home repository

Setup Debugging for VS2015

To debug the console and UI during development, following these steps:

  1. Launch Visual Studio as Administrator
  2. Make sure that the NuGet Extension is UNINSTALLED from your primary instance of VS so your newly compiled one can load into the experimental instance.
  3. Set the VsExtension project as the startup project
  4. Ensure that you rebuild the VsExtension project.
  5. Now you can run or debug the VsExtension project and this would launch a separate instance of VS2015 (called the Experimental instance) with a copy of the NuGet vsix installed. What you do in this instance don't affect the main VS instance.

Developing NuGet on Linux

The easiest distribution to use is OpenSUSE. Install OpenSUSE 13.2, then follow these steps:

  1. Install Git

     sudo zypper install git
  2. Install Mono

     sudo zypper install mono-complete
  3. Import Trusted Root Certificates. By default, Mono trusts no one. The NuGet build needs to install some packages from, and without neccessary root certificates this will fail. Run this command to import trusted root certificates from Mozilla's LXR into Mono's certificate store:

     mozroots --sync --import
  4. Clone the repository

     git clone
  5. Build NuGet Cd to the nuget source code direcotry, run


This will build NuGet.exe in directory src/CommandLine/bin/Release successfully.
