BB84.SourceGenerators

A collection of C# source generators that automatically generate boilerplate code at compile time, reducing manual coding and improving code maintainability.

Features

This package provides sixteen powerful source generators:

• Abstraction Generator - Interface and implementation generation for static classes
• ActionCommand Generator - Compile-time ICommand property generation (sync, async, parameterized, cancellable) for MVVM
• AutoMapper Generator - Compile-time property-to-property mapping method generation
• Assembly Information Generator - Compile-time assembly metadata constants without reflection
• Builder Generator - Fluent builder pattern generation for classes and structs
• Cloneable Generator - Compile-time Clone() and DeepClone() method generation with collection and struct support
• Decorator Generator - Compile-time decorator pattern generation with full interface delegation, generic methods, events, and partial method hooks
• Disposable Generator - Compile-time IDisposable / IAsyncDisposable pattern generation with ordered resource cleanup
• Enumerator Extensions Generator - Fast, allocation-free extension methods for enums
• Equality Generator - Compile-time Equals, GetHashCode, and operator generation
• Factory Generator - Compile-time factory pattern generation with automatic implementation discovery
• INI File Generator - Compile-time INI file serialization and deserialization
• Notification Properties Generator - Configurable INotifyPropertyChanged/INotifyPropertyChanging implementation
• Singleton Generator - Thread-safe singleton pattern generation with lazy or eager initialization
• ToString Generator - Compile-time ToString() override generation
• Validator Generator - Compile-time data annotation validation

Each generator has its own page covering why to use it, its benefits and usage examples. See the documentation index for an overview.

Installation

Install the package via NuGet:

dotnet add package BB84.SourceGenerators

Or via Package Manager Console:

Install-Package BB84.SourceGenerators

In the project where you want to use the generators, add a reference to the package and include the appropriate using directive for the attributes:

using BB84.SourceGenerators.Attributes;

If the attributes are not recognized, make sure that the EmitCompilerGeneratedFiles property is set to true in the project file:

<PropertyGroup>
  <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
</PropertyGroup>

Requirements

• .NET Standard 2.0 or higher
• C# 7.3 or higher
• Supports .NET Framework 4.7.2+, .NET Core 2.0+, .NET 5+, .NET 6+, .NET 7+, .NET 8+

How It Works

Source generators run during compilation and generate additional C# source files that are compiled alongside your code. This means:

• Zero runtime overhead - All code is generated at compile time
• IntelliSense support - Generated code appears in Visual Studio IntelliSense
• Debuggable - You can step through generated code during debugging
• No reflection - Generated code uses direct method calls
