Logo Zero Install .NET

API documentation Build status
Zero Install is a decentralized cross-platform software installation system. You can learn more at

This is the .NET implementation of Zero Install. It can be used as a command-line tool on various platforms or be embedded into .NET applications as a set of libraries. It provides the basis for Zero Install for Windows.


Zero Install .NET provides the 0install command-line tool. There are a number of ways you can get it:

  • You can get a .NET Framework version of the 0install command by downloading Zero Install for Windows. (recommended)

  • If you already have some version of Zero Install (.NET-based or otherwise) on your system you can use it to download and run a .NET 5 version of the 0install command like this:

    0install run
  • You can also manually install .NET 5 and then download a Zero Install .NET Release, extract the archive and run:

    dotnet 0install.dll

NuGet packages

You can use these NuGet packages to integrate Zero Install features into your own application:

Data model for the feed format.

Management of on-disk caches, signature verification, etc..
This provides a common basis for the packages ZeroInstall.Services and ZeroInstall.Publish. You will usually get this package indirectly as a dependency from there.

Core services like solving dependencies, downloading implementations and execution selections.
Zero Install itself is built upon this API. You can use the API to integrate Zero Install features into your own application, e.g. for a plugin management system.

Interfaces/abstractions for Zero Install services (contains no actual implementations).
You will usually get this package indirectly as a dependency of ZeroInstall.Services.

Methods for integrating applications with desktop environments (creating menu entries, etc.).

Command-line interface for Zero Install.
The binary in this package serves both as an actual CLI and a library for building other clients.

Utilities for creating and modifying feed files.
The Zero Install Publishing Tools (including the Feed Editor) are built upon this library. You can use this to automate complex feed creation/update tasks.

For more information read the Zero Install .NET API documentation.


The source code is in src/, config for building the API documentation is in doc/ and generated artifacts are placed in artifacts/.
The source code does not contain version numbers. Instead the version is determined during CI using GitVersion.

To build on Windows install Visual Studio 2019 v16.8 or newer and run .\build.ps1.
To build on Linux or macOS run ./
Note: Some parts of the project can only be built on Windows and are skipped in Linux/macOS builds.
