Building

Development Build

dotnet build CSharpHash/CSharpHash.csproj

Release Build (Framework-dependent)

scripts/build.cmd fd release

Build script arguments:

• fd or framework-dependent: Framework-dependent publishing (default)
• sc or self-contained: Self-contained publishing
• debug: Debug configuration
• release: Release configuration (default)

Or using individual dotnet commands:

dotnet publish CSharpHash/CSharpHash.csproj --configuration Release --self-contained false --runtime win-x64 --output ./publish

Creating Releases

To create a new release:

1. Commit your changes
2. Create a git tag: git tag v1.0.1 (version automatically set from tag name)
3. Push the tag: git push origin v1.0.1
4. GitHub Actions will automatically build and publish the release

The workflow will:

• Extract the version from the tag name (e.g., v1.0.1 → version 1.0.1)
• Build the executable with that version
• Publish the executable file to GitHub Releases

Tag Format: Use v{major}.{minor}.{patch} format (e.g., v1.2.3)

Example:

git add .
git commit -m "Add new feature"
git tag v1.0.1
git push origin main
git push origin v1.0.1  # This triggers the release build
