Versioning Guidelines

All version numbers follow the Semantic Versioning (SemVer) format

1. The version numbers of the two foundational abstraction packages start from 1.0.0 and increase incrementally:
   • Rougamo.Extensions.DependencyInjection.Abstractions
   • Rougamo.Extensions.DependencyInjection.AspNetCore.Abstractions
2. For Microsoft official DI extension packages, the major version matches the corresponding official package (e.g., Microsoft.Extensions.*):
   • Rougamo.Extensions.DependencyInjection.AspNetCore
   • Rougamo.Extensions.DependencyInjection.GenericHost
3. For Autofac extension packages, the major version matches the corresponding official Autofac package:
   • Rougamo.Extensions.DependencyInjection.Autofac.AspNetCore
   • Rougamo.Extensions.DependencyInjection.Autofac

Rougamo.Extensions.DependencyInjection.AspNetCore

Quick Start

// Register Rougamo (Note: Rougamo does not require registration if you do not need IoC/DI features)
public static void Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    // ... other setup steps
    builder.Services.AddRougamoAspNetCore();
    // ... other setup steps
}

// Accessing IServiceProvider in an aspect
public class TestAttribute : MoAttribute
{
    public override void OnEntry(MethodContext context)
    {
        // Use the extension method GetServiceProvider to obtain the IServiceProvider instance
        var services = context.GetServiceProvider();

        // Utilize IServiceProvider
        var xxx = services.GetService<IXxx>();
    }
}

Non-HttpContext Scope

By default, the extension method GetServiceProvider on MethodContext only attempts to retrieve the IServiceProvider for the current HttpContext scope. If there is no HttpContext, it will return the root IServiceProvider. This design assumes that in AspNetCore projects, scopes are typically not manually created. If you have a scenario where you need to manually create a scope, follow the steps below:

public static void Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    // ... other setup steps
    builder.Services.AddNestableHttpContextScopeAccessor();  // Additional registration step
    builder.Services.AddRougamoAspNetCore();
    // ... other setup steps
}

public class Cls(IServiceProvider services)
{
    public void M()
    {
        // Use the extension method CreateResolvableScope to create a scope.
        // If you use CreateScope, that scope will not be accessible in aspect types.
        using var scope = services.CreateResolvableScope();
    }
}

Rougamo.Extensions.DependencyInjection.GenericHost

// Register Rougamo (Note: Rougamo does not require registration if you do not need IoC/DI features)
public static void Main(string[] args)
{
    var builder = Host.CreateDefaultBuilder();
    // ... other setup steps
    builder.ConfigureServices(services => services.AddRougamoGenericHost());
    // ... other setup steps
}

// Accessing IServiceProvider in an aspect
public class TestAttribute : MoAttribute
{
    public override void OnEntry(MethodContext context)
    {
        // Use the extension method GetServiceProvider to obtain the IServiceProvider instance
        var services = context.GetServiceProvider();

        // Utilize IServiceProvider
        var xxx = services.GetService<IXxx>();
    }
}

Rougamo.Extensions.DependencyInjection.Autofac.AspNetCore

Quick Start

// Register Rougamo (Note: Rougamo does not require registration if you do not need IoC/DI features)
public static void Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    builder.Host
            .UseServiceProviderFactory(new AutofacServiceProviderFactory())
            .ConfigureContainer<ContainerBuilder>(builder =>
            {
                builder.RegisterRougamoAspNetCore();
            });
    
    // Registering IHttpContextAccessor is also required
    builder.Services.AddHttpContextAccessor();
}

// Accessing ILifetimeScope in an aspect
public class TestAttribute : MoAttribute
{
    public override void OnEntry(MethodContext context)
    {
        // Use the extension method GetAutofacCurrentScope to obtain the ILifetimeScope instance
        var scope = context.GetAutofacCurrentScope();

        // Utilize ILifetimeScope
        var xxx = scope.Resolve<IXxx>();
    }
}

Non-HttpContext Scope

By default, the GetAutofacCurrentScope extension method on MethodContext only attempts to retrieve the ILifetimeScope for the current HttpContext. If there is no HttpContext, it will return the root IServiceProvider. This design assumes that in AspNetCore projects, scopes are typically not manually created. If you have a scenario where you need to manually create a scope, follow the steps below:

public static void Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    builder.Host
            .UseServiceProviderFactory(new AutofacServiceProviderFactory())
            .ConfigureContainer<ContainerBuilder>(builder =>
            {
                builder.RegisterAutofacNestableHttpContextScopeAccessor(); // Additional registration step
                builder.RegisterRougamoAspNetCore();
            });
    
    // Registering IHttpContextAccessor is also required
    builder.Services.AddHttpContextAccessor();
}

public class Cls(IServiceProvider services)
{
    public void M()
    {
        // Use the extension method BeginResolvableLifetimeScope to create a scope.
        // If you use BeginLifetimeScope, that scope will not be accessible in aspect types.
        using var scope = services.BeginResolvableLifetimeScope();
    }
}

Rougamo.Extensions.DependencyInjection.Autofac

// Register Rougamo (Note: Rougamo does not require registration if you do not need IoC/DI features)
public static void Main(string[] args)
{
    var builder = Host.CreateDefaultBuilder();
    
    builder
        .UseServiceProviderFactory(new AutofacServiceProviderFactory())
        .ConfigureContainer<ContainerBuilder>(builder =>
        {
            builder.RegisterRougamo();
        });
}

// Accessing ILifetimeScope in an aspect
public class TestAttribute : MoAttribute
{
    public override void OnEntry(MethodContext context)
    {
        // Use the extension method GetAutofacCurrentScope to obtain the ILifetimeScope instance
        var scope = context.GetAutofacCurrentScope();

        // Utilize ILifetimeScope
        var xxx = scope.Resolve<IXxx>();
    }
}

Usage in Framework Projects

If your project is an older WebForm, WinForm, WPF, or similar project that does not use the Microsoft.Extensions.* packages, you can directly call the RegisterRougamo extension method when initializing the ContainerBuilder.

var builder = new ContainerBuilder();
builder.RegisterRougamo();
