Introduction

In software development, maintaining version control of assemblies is a crucial part of the continuous integration (CI) process. Auto-incrementing the assembly version ensures that each build is uniquely identifiable, aiding in tracking changes, bug fixes, and enhancements. This article delves into how you can automatically increment the C# assembly version using the CI platform Hudson, a popular choice for developers.

Understanding Assembly Versioning

AssemblyVersion Attribute

In .NET, the `AssemblyVersion` attribute represents the version of the assembly being generated. It follows the format `major.minor.build.revision`, where:

• Major: A significant release, possibly with breaking changes.
• Minor: Minor changes, typically backward-compatible.
• Build: Incremented for every build, usually initiated manually or automatically.
• Revision: Often used for bug fix updates or additional changes.

Example in `AssemblyInfo.cs`:

• A basic understanding of C# and .NET assemblies.
• Hudson installed with necessary build tools.
• Git or any other version control system integrated with Hudson.
• Create a New Job: Log into Hudson and create a new job specifically for your C# project.
• Source Code Management: Configure the source code repository, usually Git.
• Build Environment: Set up any environment variables or prerequisites needed, such as .NET SDK paths.
• Build Steps: In your Hudson job configuration, add a build step to execute a Windows batch command or invoke a PowerShell script.
• Script Execution: Use the PowerShell example provided to update the assembly version automatically before the build process.
• Build Triggers: Set conditions for when the build should trigger, such as changes in the source code repository or time-scheduled builds.
• Execute the Build: Start a build manually or let Hudson trigger it based on the configured conditions.
• Consistency and Traceability: Each build is uniquely identifiable, aiding in code rollback or debugging.
• Reduced Manual Error: Eliminates the need for developers to manually increment versions, which can lead to errors.
• Efficient CI/CD Workflow: Integrating versioning into Hudson streamlines the release pipeline and ensures best practices in software delivery.
