Excalibur.Dispatch.SourceGenerators

Source generators for the Excalibur framework, enabling AOT-compatible code generation at compile time.

Quick Start

1. Install

dotnet add package Excalibur.Dispatch.SourceGenerators

2. Mark Services with `[AutoRegister]`

using Excalibur.Dispatch.Abstractions;
using Microsoft.Extensions.DependencyInjection;

// Basic usage - Scoped lifetime, registers as self and interfaces
[AutoRegister]
public class OrderHandler : IDispatchHandler<CreateOrderCommand>
{
    public Task<IMessageResult> HandleAsync(
        CreateOrderCommand message,
        IMessageContext context,
        CancellationToken ct)
    {
        // Handle the command
        return Task.FromResult(MessageResult.Success());
    }
}

// Explicit Singleton lifetime
[AutoRegister(Lifetime = ServiceLifetime.Singleton)]
public class CacheService : ICacheService { }

// Interfaces only (no concrete type registration)
[AutoRegister(AsSelf = false, AsInterfaces = true)]
public class MultiService : IFirst, ISecond { }

3. Call the Generated Extension

var builder = WebApplication.CreateBuilder(args);

// Register all [AutoRegister] services
builder.Services.AddGeneratedServices();

// Add Excalibur framework
builder.Services.AddDispatch();

var app = builder.Build();

Features

Feature	Description
[AutoRegister] Attribute	Opt-in service registration at compile time
AOT Compatibility	Full Native AOT and trimming support
Lifetime Control	Singleton, Scoped, or Transient per service
Interface Registration	Control self vs interface registration
Zero Reflection	All discovery happens at compile time

Attribute Options

[AutoRegister(
    Lifetime = ServiceLifetime.Scoped,  // Default: Scoped
    AsSelf = true,                       // Default: true - register as concrete type
    AsInterfaces = true                  // Default: true - register for interfaces
)]
public class MyService : IMyService { }

Generated Output

The generator creates AddGeneratedServices() in Microsoft.Extensions.DependencyInjection:

public static class GeneratedServiceCollectionExtensions
{
    public static IServiceCollection AddGeneratedServices(this IServiceCollection services)
    {
        services.AddScoped<MyService>();
        services.AddScoped<IMyService, MyService>();
        return services;
    }
}
