SoftwareExtravaganza.Whizbang.Migrate 0.9.4

Whizbang

A comprehensive .NET library for building event-driven, CQRS, and event-sourced applications with zero reflection and AOT compatibility.

Version 0.1.0 - Foundation Release

This is the foundation release establishing all core components with in-memory implementations. The focus is on breadth over depth, ensuring every component exists and works together from day one.

Core Components (v0.1.0)

Receptors

Stateless message handlers that receive commands and produce events. Type-safe with flexible response types (single, tuple, array, Result<T>).

Dispatcher

Message routing and orchestration engine. Routes messages to appropriate handlers with context tracking (correlation/causation IDs).

Value Objects (Vogen)

Type-safe IDs using source-generation:

• MessageId - Unique message identifier
• CorrelationId - Logical workflow identifier
• CausationId - Causal chain identifier

Technology Stack

• .NET 10.0 - Target framework (LTS)
• Vogen - Source-generated value objects
• TUnit 1.5+ - Modern source-generation test framework
• TUnit.Assertions - Native fluent assertions
• Rocks 9.3+ - Source-generation mocking for AOT compatibility
• Bogus - Test data generation
• EF Core 10 - Database access with compiled models
• Dapper - High-performance SQL queries
• PostgreSQL - Primary database with JsonB and UUIDv7 support

Getting Started

Build

dotnet build

Run Tests

dotnet test

Current Status

All tests are currently failing by design. This is TDD - tests define the behavior, implementation comes next.

Philosophy

• Zero Reflection - Everything via source generators
• AOT Compatible - Native AOT from day one
• Type Safe - Compile-time safety everywhere
• Test Driven - Comprehensive test coverage

Documentation

See the whizbang-lib.github.io repository for comprehensive documentation of all features and design decisions.

Release Workflow

Three-Phase Release Process

Whizbang uses a three-phase release process:

1. Alpha - Internal testing and validation
2. Beta - Limited public testing with early adopters
3. GA - General availability for public use

Release Checklist

The complete release checklist is maintained in .github/RELEASE.md.

Using the /release Command

Claude Code can guide you through the release process:

/release alpha   # Start alpha release
/release beta    # Start beta release
/release ga      # Start GA release

Manual Release Process

If not using Claude Code, follow these steps:

Alpha Release

1. Follow all items in .github/RELEASE.md Alpha Phase section
2. Verify all exit criteria are met
3. Tag version: git tag -a v0.1.0-alpha.1 -m "Alpha 1"
4. Push tag: git push origin v0.1.0-alpha.1
5. GitHub Actions will automatically publish to NuGet

Beta Release

1. Complete Alpha phase
2. Address feedback from alpha testing
3. Follow all items in .github/RELEASE.md Beta Phase section
4. Tag version: git tag -a v0.1.0-beta.1 -m "Beta 1"
5. Push tag: git push origin v0.1.0-beta.1

GA Release

1. Complete Beta phase
2. Address feedback from beta testing
3. Follow all items in .github/RELEASE.md GA Phase section
4. Tag version: git tag -a v0.1.0 -m "Release v0.1.0"
5. Push tag: git push origin v0.1.0
6. Announce to community

Version Numbering

See GitVersion section for automatic version calculation.

Next Steps

1. ✅ Foundation skeleton (DONE)
2. ⏳ Implement Receptors to pass tests
3. ⏳ Implement Dispatcher to pass tests
4. ⏳ Add source generators for handler discovery
5. ⏳ Add remaining components (Perspectives, Lenses, etc.)

Contributing

This is v0.1.0 - the foundation. Follow the TDD approach:

1. Tests define behavior (already written)
2. Implement to make tests pass (green)
3. Refactor for quality (refactor)

See CONTRIBUTING.md for full guidelines.
