# DotNet.ReproducibleBuilds

.NET Foundation Build Status

This repo is a collection of best practices for build reproducibility with MSBuild.

It provides documentation and NuGet packages to simplify build configuration and isolate builds from developer or workstation-specific settings.

DotNet.ReproducibleBuilds nuget package

NuGet Version NuGet Downloads

It's highly recommended that all projects enable these settings, either via adding this package or manually as described here: https://devblogs.microsoft.com/dotnet/producing-packages-with-source-link/

This package sets the following properties:

It also adds SourceLink dependencies for all repo types (the right one will be used automatically).

For more information on debugging with Source Link is here.

Usage

Add the following to your Directory.Build.props file so all projects in your solution have the package added -- use the latest package version.

<ItemGroup>
  <PackageReference Include="DotNet.ReproducibleBuilds" Version="1.2.4" PrivateAssets="All"/>
</ItemGroup>

MSBuild 16.10 is required to generate binaries that can be fully reproduced. You'll need Visual Studio 2019 16.10 and/or .NET 5.0.300 SDK. You'll get a warning if you're using a lower version.

Prerelease packages are available on the following NuGet feed: https://pkgs.dev.azure.com/dotnet/Projects/_packaging/ReproducibleBuilds/nuget/v3/index.json

DotNet.ReproducibleBuilds.Isolated Documentation and nuget package

NuGet Version NuGet Downloads

It's highly recommended that all projects enable these settings, either via adding this package or manually, as described in Documentation/Reproducible-MSBuild.

This package configures a variety of properties and item groups to prevent your build from unintentionally depending on other installed software that's not described by your repo. All build dependencies should come from either the MSBuild SDK you've chosen, or from nuget packages restored from your package feed.

If you check out the same commit with the same SDK version and same nuget feed, you should get the same build result.

Usage

Add the following to the top of your projects or to Directory.Build.props:

<Sdk Name="DotNet.ReproducibleBuilds.Isolated" Version="1.2.4" />

Tested on MSBuild 16.7 (Latest LTS at time of writing).
