MassiveDynamicProxyGenerator.Microsoft.DependencyInjection 1.3.0-preview1

MassiveDynamicProxyGenerator.Microsoft.DependencyInjection

MassiveDynamicProxyGenerator.Microsoft.DependencyInjection is library of extensions method for Microsoft.Extensions.DependencyInjection IoC container. Adding methods for decorators, proxys, instance proxies for resolving circular depndencies or lazy initialization and interpetion for decoration instances.

Microsoft.Extensions.DependencyInjection is simple IoC container, so MassiveDynamicProxyGenerator.Microsoft.DependencyInjection does just a simple extenion for fetures from MassiveDynamicProxyGenerator library, becose any fetures don't support open generics.

Getting started

In package manager console:

PM> Install-Package MassiveDynamicProxyGenerator.Microsoft.DependencyInjection

Or download MassiveDynamicProxyGenerator.Microsoft.DependencyInjection.

Add decorators

This feture unrelated with MassiveDynamicProxyGenerator, it is universal adding interface generators.

using MassiveDynamicProxyGenerator.Microsoft.DependencyInjection;

public class MessageServiceDecorator : IMessageService
{
    public MessageServiceDecorator(IMessageService messageService, ILogger<MessageServiceDecorator> logger)
    {
        // ...
    }

    // ...
}

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        this.Configuration = configuration;
    }

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddTransient<IMessageService, RealMessageService>();
        services.AddDecorator<IMessageService, MessageServiceDecorator>();
        services.AddMvc();

        return services.BuldIntercepedServiceProvider();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //...
    }
}
    

Add Proxy

using MassiveDynamicProxyGenerator.Microsoft.DependencyInjection;

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        this.Configuration = configuration;
    }

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.Addproxy<IMessageService>(new MyInterceptor());
        // or
        services.AddTransient<MyInterceptor>();
        services.Addproxy<IMessageService, MyInterceptor>();
        // or
        services.Addproxy<IMessageService>(typeof(MyInterceptor));
        // or
        services.AddTransient<IMessageService>(invocation => {
            //... any work with invocation
        });
        
        services.AddMvc();

        return services.BuldIntercepedServiceProvider();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //...
    }
}
    

Add Intercepred Decorator

using MassiveDynamicProxyGenerator.Microsoft.DependencyInjection;

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        this.Configuration = configuration;
    }

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddTransient<IMessageService, RealMessageService>();

        services.AddInterceptedDecorator<IMessageService>(new MessageCallableInterceptor());
        // or
        services.AddInterceptedDecorator<IMessageService, MessageCallableInterceptor>();
        // or
        services.AddInterceptedDecorator(type => type.Name.EndsWith("Service"), 
            serviceProvider => new LoggingInterceptor(serviceProvider.GetRequiredService<ILogger>()));
        // or
        services.AddInterceptedDecorator<IMessageService>(new CallableInterceptorAdapter(invocation =>
        {
            // operations before real methd call
            invocation.Process();
            // operations after real methd call
        }));

        services.AddMvc();

        return services.BuldIntercepedServiceProvider();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //...
    }
}
    

Add Instance Proxy

using MassiveDynamicProxyGenerator.Microsoft.DependencyInjection;

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        this.Configuration = configuration;
    }

    public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        services.AddInstanceProxy<IMessageService>(new MessageServiceInstanceProvider());
        //or 
        services.AddInstanceProxy<IMessageService>(() => new RealMessageService());

        services.AddMvc();

        return services.BuldIntercepedServiceProvider();
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //...
    }
}
