FractalDataWorks.Configuration 0.1.3-alpha-gc2820fa97d

FractalDataWorks Developer Kit

A comprehensive .NET library framework providing foundational abstractions and implementations for building scalable, maintainable enterprise applications.

Overview

The FractalDataWorks Developer Kit is a layered architecture framework that provides:

• Core abstractions for services, configuration, validation, and results
• Service patterns with built-in validation, logging, and error handling
• Configuration management with validation and registry patterns
• Enhanced messaging using the EnhancedEnums pattern for type-safe, maintainable messages
• Extensible architecture supporting dependency injection, data access, hosting, and tools

Architecture

The framework follows a progressive layered architecture:

Layer 0.5 - Core Foundation (No Dependencies)

• FractalDataWorks.net - Core abstractions and base types (targets netstandard2.0 for maximum compatibility)
  • IFractalService - Base service abstraction
  • IFractalConfiguration - Configuration abstraction
  • IServiceResult & FractalResult<T> - Consistent result pattern
  • ServiceMessage - Enhanced enum-based messaging system
  • IFractalValidator<T> - Validation abstractions

Layer 1 - Domain-Specific Abstractions

• FractalDataWorks.Services - Service patterns and base implementations

  • ServiceBase<TConfiguration, TCommand> - Base service with validation and logging
  • IConfigurationRegistry<T> - Configuration management pattern
  • Built-in command validation and error handling

• FractalDataWorks.Configuration - Configuration providers and patterns

  • ConfigurationBase<T> - Self-validating configuration base class
  • ConfigurationProviderBase - Provider pattern implementation
  • ConfigurationSourceBase - Configuration source abstractions

• FractalDataWorks.Connections - Data and messaging connection abstractions

  • Connection interfaces for various data sources
  • Retry and resilience patterns

• FractalDataWorks.DependencyInjection - DI container abstractions

  • Container-agnostic dependency injection patterns
  • Service registration extensions

• FractalDataWorks.Tools - Common utilities and helpers

  • Extension methods and utility classes
  • Common helper functions

• FractalDataWorks.Hosts - Web and worker host abstractions

  • Host service abstractions
  • Background service patterns

• FractalDataWorks.Data - Data abstractions and common types

  • Repository patterns
  • Data access abstractions

Git Workflow

This repository follows a git-flow branching strategy:

1. master - Production-ready releases only
2. develop - Main development branch
3. feature/ - Feature branches
4. beta/ - Beta release branches
5. release/ - Release candidate branches
6. experimental/ - Experimental features

Setting up the Development Branch

After cloning, create the develop branch from master:

git checkout -b develop
git push -u origin develop

Creating Feature Branches

Always branch from develop:

git checkout develop
git pull origin develop
git checkout -b feature/your-feature-name

Building and Testing

Prerequisites

• .NET 10.0 Preview SDK
• Visual Studio 2022 Preview or VS Code

Build Commands

# Restore packages
dotnet restore

# Build solution
dotnet build

# Run tests
dotnet test

# Pack NuGet packages
dotnet pack

Configuration-Specific Builds

# Debug build (default)
dotnet build

# Alpha build
dotnet build -c Alpha

Package Dependencies

Each Layer 1 package depends on FractalDataWorks.net. Additional dependencies:

• FractalDataWorks.DependencyInjection also depends on FractalDataWorks.Configuration
• FractalDataWorks.Hosts also depends on FractalDataWorks.Services

Testing

All projects use xUnit.v3 for testing. Test projects follow the naming convention: FractalDataWorks.[Package].Tests

Run tests with:

dotnet test

Key Features

Service Pattern

public class MyService : ServiceBase<MyConfiguration, MyCommand>
{
    public MyService(ILogger<MyService> logger, IConfigurationRegistry<MyConfiguration> configs)
        : base(logger, configs)
    {
    }

    protected override async Task<FractalResult<TResult>> ExecuteCore<TResult>(MyCommand command)
    {
        // Implementation with automatic validation and error handling
    }
}

Configuration Management

public class MyConfiguration : ConfigurationBase<MyConfiguration>
{
    public string ConnectionString { get; set; }
    public int Timeout { get; set; }
    
    protected override FluentValidation.Results.ValidationResult ValidateCore()
    {
        var validator = new MyConfigurationValidator();
        return validator.Validate(this);
    }
}

Enhanced Messaging

// Type-safe, discoverable service messages
_logger.LogError(ServiceMessages.InvalidConfiguration.Format("Missing connection string"));
_logger.LogInformation(ServiceMessages.ServiceStarted.Format(ServiceName));

// Messages are strongly-typed with consistent formatting
var message = ServiceMessages.ConnectionFailed;
_logger.LogError(message.Format(retries, errorMessage));

Result Pattern

// Consistent error handling across all services
var result = await service.Execute<Customer>(command);
if (result.IsSuccess)
{
    return Ok(result.Value);
}
else
{
    return BadRequest(result.Error);
}

Code Quality

The framework enforces code quality through:

• Analyzers: StyleCop, AsyncFixer, Meziantou.Analyzer, Roslynator
• Threading Analysis: Microsoft.VisualStudio.Threading.Analyzers
• XML Documentation: Required for all public/protected members
• Testing: xUnit v3 with parallel execution
• Coverage: Coverlet integration for code coverage
• Build Configurations: Progressive quality gates from Debug to Release
