What is this?

Have you ever wanted to embed the current version of .NET, its documentation, etc.? Furthermore, have you ever wanted to automate such an operation with CI, but found the additional work to be too opaque and numerous?

In C#, such information is conventionally described in the AssemblyInfo.cs file:

using System.Reflection;.

// Embed version number in assembly attribute.
[assembly: AssemblyVersion("1.0.21")]

However, this is as far as the standard goes. It was the developer's responsibility to properly update the embedded version number.

RelaxVersioner makes version embedding extremely simple by applying versions via Git tagging. Simply put, you can tag a Git tag with 1.0.21 and it will automatically generate and embed an assembly attribute like the one shown above!

The assembly with the embedded version number can be partially viewed in the Properties page of Explorer:

If you look in ILSpy, you will also see all the information:

• Simply install RelaxVersioner's NuGet package into your .NET project and it will embed the version number from your Git tags completely automatically at build time.
  • Don't worry about untagged commits. It can go back in time, find the tag, and apply the automatically incremented version.
• This is not just a tag. It also embeds additional information such as commit ID, branch name, author name, date and etc. The format can be freely changed.
• You can also customize the information to be embedded. For example, by embedding the value of variables used in MSBuild, you can also embed detailed information at build time.
• Version embedding is fully integrated into MSBuild. This means that you can simply install the NuGet package and embed versions directly in the build process of IDEs such as Visual Studio, Rider, Visual Studio Code or in the build process of CI.
  • RelaxVersioner does not contain any environment-dependent code, so it works in almost any .NET environment.
• A CLI interface also exists. You can embed version numbers in text documents and apply the same version notation to different project systems than .NET (e.g. Makefile and etc.).
  • CLI has a dedicated NPM (Node.js package manager) mode, which allows you to easily centralize NPM project and version operations.

Sample output code

The following is a C# example, but F#, VB.net, and C++/CLI are also supported. The output attributes are the same.

In addition to the assembly attributes, a ThisAssembly symbol is also defined. This has the advantage that you can easily retrieve various version information without having to use reflection to search for the attributes:

using System.Reflection;

[assembly: AssemblyVersion("1.0.21")]
[assembly: AssemblyFileVersion("2020.12.20.33529")]
[assembly: AssemblyInformationalVersion("1.0.21-561387e2f6dc90046f56ef4c3ac501aad0d5ec0a")]

Getting started

Start guide

• An easy way to practice version embedding on .NET (dev.to)
• Refer start guides.

How to use

• Search NuGet repository: "RelaxVersioner", and install.
• (Optional if you're using old MSBuild project): Before build, comment out "AssemblyVersion" and "AssemblyFileVersion" attribute in AssemblyInfo.cs default definitions (will cause build error by duplicate definition). If you use custom rule set, continue use this definitions.
• After installed, build project. Auto-apply version informations into assembly attributes. Some attributes are looking for ILSpy or Windows Explorer property page.
• You can use custom rule set file naming "RelaxVersioner.rules" into project folder "$(ProjectDir)" or solution folder "$(SolutionDir)". Current no documentation custom rule set file, see also below.

Example for development cycles

1. You create new C#,F# or another project.
2. Install "RelaxVersioner" from NuGet.
3. (Optional): Comment outs default "AssemblyVersion" and "AssemblyFileVersion" declarations in AssemblyInfo.cs.
4. Let's build now! Output binary applied version informations.
   • Default declaration of AssemblyVersion="0.0.1.0", AssemblyFileVersion="(Build date on 2sec prec.)" (ex:"2016.05.12.11523"）
   • Applied AssemblyVersionMetadata from local Git repository (Author, Branch, Tags）. But this example git repository not created , so there declarations containing "Unknown".
5. Create Git local repository (command: git init). And commit with message.
6. Build retry. Output binary applied Author, Branch, Tags now.
7. You are tagging current commit. For example "0.5.4" or "v0.5.4". Rebuild, then contains AssemblyVersion is "0.5.4" now.
   • The auto increment feature: If your current commit doesn't apply any tags, RelaxVersioner will traverse committing history and auto increment commit depth for tail of version component. For example, tagged "0.5.4' at 2 older commit. The auto incrementer will calculate version "0.5.6".
   • RelaxVersioner will traverse first priority for primary parent and then next others. Therefore, if you're using branch strategy, you can apply auto increment with different version each branch when tagged different version each branch at bottom commit. For example: The tick-tock model for the master branch tagged "1.0.0" and devel branch tagged "1.1.0".
8. All rights codes, tags. Push to remote repository, all done.
9. Development cycles: next codes change and ready to release, you are tagging new version and then build, output binary auto tagged in AssemblyVersion and store informations.
   • We can apply with automated version number when "dotnet cli" for generate NuGet package (PackageVersion and PackageReleaseNotes attributes). You can use only dotnet pack command.

---

Command line interface (CLI)

RelaxVersioner supports the dotnet CLI tool. The rv command can be installed with:

$ dotnet tool install -g rv-cli

You can easily obtain the version string by using the rv command as follows:

$ rv .
1.2.3.4

You can use -f to get different output. For example:

# Standard version format
$ rv -f "{versionLabel}" .
1.2.3.4

# Commit ID
$ rv -f "{commitId}" .
01234567899abc ...

# Complex formats are also possible
$ rv -f "{commitId}:{commitDate:yyyyMMdd}/{branches}" .
0123456789 ...:20240123/develop,main

• Please refer to below section such as versionLabel, commitId and etc. that are specified as placeholders.
  • Note: tfm, tfid, tfv, tfp, namespace and buildIdentifier cannot be recognized unless they are specified as command line options.

You can use the -o option to output directly to a file. In this case, no newlines are included at the end of the line:

# Output to the file
$ rv -o version.txt .
$ cat version.txt
1.2.3.4

If you use the -r or -i options, you will be in “replace mode”, which allows you to directly replace arbitrary text. Using this mode, you can perform bulk text replacements in a more direct way:

# Replace text on standard input
$ echo "@@@{commitId}@@@" | rv -r .
@@@0123456789abc ... @@@

# Replace specified file text
$ rv -i input.txt -o output.txt .

The standard bracket for the replacement keyword is in the form of braces '{ ... }', but different bracket characters can be used. For example, when applied to a document, braces can cause false positives, so a custom bracket is used to replace them:

# Replace with custom brackets
# Separate left and right bracket definitions with commas
$ echo "ABC#{commitId}#XYZ" | rv -r --bracket "#{,}#" .
ABC0123456789abc ... XYZ

With this CLI, you can use a combination of RelaxVersioner for different targets than .NET. For example, in a CI/CD environment like GitHub Actions, you can apply versions to NPM package generation or embed versions in your text documentation.

---

Using with Node.js projects

The CLI interface has special options for NPM (Node.js package manager). Change to the directory where the package.json file is located and run the CLI as follows:

$ rv --npm .
RelaxVersioner [3.8.0]: Generated versions code: Language=NPM, Version=12.34.56

The value of the version key in package.json will then be replaced with the correct version value.

• This function is similar to the standard NPM npm version command.
• The version search algorithm is based on RelaxVersioner, so it is useful if you want to share the same version with .NET projects.

Furthermore, if you use the --npmns option, you can also change the package versions that the package depends on at the same time. For example, if you are managing multiple packages and there are dependencies between the packages:

{
  "name": "webapi-interaction",
  "version": "0.0.1",             // <-- The version of this package (before updating)
  "dependencies": {
    "@foobar/helpers": "^1.4.0",  // <-- Version of the managed package that is a dependency
    "@foobar/common": "^1.7.2",   // <-- Version of the managed package that is a dependency
    "dayjs": "^1.2.3"
  }
}

Run the CLI specifying the namespace of the package name (@foobar) that is a dependency:

$ rv --npmns @foobar .

This will unify all the version numbers:

{
  "name": "webapi-interaction",
  "version": "13.24.5",             // <-- Automatically updated
  "dependencies": {
    "@foobar/helpers": "^13.24.5",  // <-- automatically updated (dependency)
    "@foobar/common": "^13.24.5",   // <-- automatically updated (dependency)
    "dayjs": "^1.2.3"               // <-- not updated
  }
}

• Dependency checks are performed on the dependencies, peerDependencies and devDependencies keys.
• Please use a consistent package namespace to identify dependent packages.
  • In practice, this is a simple prefix match, so any name that can be identified is fine.
  • If you are targeting multiple namespaces, specify them separated by commas.
• The version of a dependent package is automatically prefixed with ^.

This function is intended to be used with NPM workspaces and inside the CI process. In that case, please follow the NPM workspaces handling, such as using * as the version number of the referenced package. After updating the version of each package, run npm install in the workspace root directory to update the correct version numbers in package-lock.json.

Hints and Tips

How to use version numbers after building process

RelaxVersioner saves the files in the following location after build:

<your project dir>/obj/<configuration>/<tfm>/

To be precise:

• $(IntermediateOutputPath) at build time.
• $(NuspecOutputPath) at NuGet package generation.

For example, FooBarProject/obj/Debug/net6.0/ directory hierarchy. Here are the files to save:

• RelaxVersioner_Metadata.cs : Source code including version attributes and ThisAssembly class definition, which is the core feature of RelaxVersioner.
• RelaxVersioner_Properties.xml : A dump of all MSBuild properties in XML format, just before RelaxVersioner calculates the version.
• RelaxVersioner_Result.xml : An XML dump of the main version information after RelaxVersioner has calculated the version.
• RelaxVersioner_Version.txt : A text file containing only the version number after RelaxVersioner has calculated the version.
• RelaxVersioner_ShortVersion.txt : A text file containing only the short version number after RelaxVersioner has calculated the version.
• RelaxVersioner_SafeVersion.txt : A text file containing only the safe (safe-numerical-notate) version number after RelaxVersioner has calculated the version.
• RelaxVersioner_Branch.txt : a text file containing the name of the checkout branch from the time RelaxVersioner has calculated the version.
• RelaxVersioner_Tags.txt : A text file containing the tags corresponding to the commits when RelaxVersioner has calculated the version.

If you want to reference this information from your program, you can get it from the version attributes or ThisAssembly. Other, XML or text files can be referenced by CI/CD (Continuous Integration and Continuous Deployment) to apply version information to the build process. For example, RelaxVersioner_ShortVersion.txt contains a string like 2.5.4, so you may be able to save your build artifacts with a version number when you upload them to the server.

If you want to reference this information from within the MSBuild target, you can use the properties as follows without having to access the text file:

  <Target Name="AB" AfterTargets="Compile">
    <Message Importance="High" Text="PropertiesPath: $(RelaxVersionerPropertiesPath)" />
    <Message Importance="High" Text="ResultPath: $(RelaxVersionerResultPath)" />
    <Message Importance="High" Text="ResolvedVersion: $(RelaxVersionerResolvedVersion)" />
    <Message Importance="High" Text="ResolvedShortVersion: $(RelaxVersionerResolvedShortVersion)" />
    <Message Importance="High" Text="ResolvedSafeVersion: $(RelaxVersionerResolvedSafeVersion)" />
    <Message Importance="High" Text="ResolvedIntDateVersion: $(RelaxVersionerResolvedIntDateVersion)" />
    <Message Importance="High" Text="ResolvedEpochIntDateVersion: $(RelaxVersionerResolvedEpochIntDateVersion)" />
    <Message Importance="High" Text="ResolvedCommitId: $(RelaxVersionerResolvedCommitId)" />
    <Message Importance="High" Text="ResolvedBranch: $(RelaxVersionerResolvedBranch)" />
    <Message Importance="High" Text="ResolvedTags: $(RelaxVersionerResolvedTags)" />
  </Target>

RelaxVersioner_Properties.xml contains a lot of very useful information, and you may be able to pull information from this XML file to meet your specific needs without having to write custom MSBuild scripts.

SourceLink integration

Sourcelink is a cool stuff debugger integration package for showing source code on-the-fly downloading from Git source code repository.

RelaxVersioner already supported Sourcelink integration. You can integrate using both RelaxVersioner and Sourcelink on simple step:

<!-- Example common properties for Sourcelink integration -->
<PropertyGroup>
  <!-- Will embed project untracked source files -->
  <EmbedUntrackedSources>true</EmbedUntrackedSources>

  <!-- Symbol embedding is recommended -->
  <DebugType>embedded</DebugType>

  <!-- Or you have to include symbol files (*.pdb) into same package -->
  <!-- <DebugType>portable</DebugType> -->
  <!-- <AllowedOutputExtensionsInPackageBuildOutputFolder>.pdb</AllowedOutputExtensionsInPackageBuildOutputFolder> -->

  <!-- Required: Will include Git repository information into assembly -->
  <PublishRepositoryUrl>true</PublishRepositoryUrl>
  <RepositoryType>git</RepositoryType>
  <RepositoryUrl>https://github.com/kekyo/Epoxy.git</RepositoryUrl>
</PropertyGroup>

<!-- Will build deterministic binary on GitHub CI Release building -->
<PropertyGroup Condition="'$(Configuration)' == 'Release'">
  <Deterministic>true</Deterministic>
  <ContinuousIntegrationBuild>true</ContinuousIntegrationBuild>
</PropertyGroup>

<ItemGroup>
  <!-- RelaxVersioner -->
  <PackageReference Include="RelaxVersioner" Version="2.12.0" PrivateAssets="All" />

  <!-- Root directory location of the solution file, if it exists. -->
  <!-- Refer: https://github.com/dotnet/roslyn/issues/37379 -->
  <SourceRoot Include="$(MSBuildThisFileDirectory)/"/>
</ItemGroup>

<!-- Required: Add Sourcelink package reference on only Release build -->
<ItemGroup Condition="'$(Configuration)' == 'Release'">
  <PackageReference Include="Microsoft.SourceLink.GitHub" Version="1.1.1" PrivateAssets="All" />
</ItemGroup>

For more further informations, see Sourcelink documentation.

CI process trouble shooting

If your CI process causes error with this description like:

RelaxVersioner [2.12.0]: NotFoundException=object not found -
   no match for id (a2b834535c00e7b1a604fccc28cfebe78ea0ec31),
   Unknown exception occurred, ...

It means your clone repository contains only 1 depth commit or some. (And couldn't find these commit id.) You must clone all commits into CI workspace.

For example, GitHub Actions checkout@v2 task will clone only 1 depth for defaulted. Because it makes better fast cloning.

RelaxVersioner (and other automated versioning tool) requires all commits for calculating version depth. Apply fetch-depth: 0 predication into your build.yml script. You can understand with this real script.

Use nuspec file to generate NuGet package

When you are using a nuspec file to generate a NuGet package, there are additional symbols available besides the default placeholders, we can do automated building NuGet package with nuspec file. Please refer to the example below:

<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
  <metadata>
    <!-- Embedding package version -->
    <version>$PackageVersion$</version>

    <!-- Embedding branch name and commit ID -->
    <repository type="git" url="https://example.com/your/repo.git" branch="$RepositoryBranch$" commit="$RepositoryCommit$" />

    <!-- Embedding commit message -->
    <releaseNotes>$PackageReleaseNotes$</releaseNotes>
  </metadata>
</package>

• Add the prepared nuspec file to the project and specify it with the NuSpecFile property inside of PropertyGroup. The rest of the procedure is the same as the general NuGet packaging procedure.

Another topics

• RelaxVersioner supported on Visual Studio 2012/2013 only installed .NET Framework 4.6 or upper. Because it requires uses compatibility for net461 MSBuild.Framework assembly.
