Usage

//C#11(NET7+) support generic attribute
[AutoInject<T>(ServiceLifetime.Scoped)]

[AutoInject]
[AutoInject(serviceLifetime: ServiceLifetime.Transient)]
[AutoInject(typeof(ITest2Service), ServiceLifetime.Scoped)]


//C#12(NET8+) support keyed service
[AutoInjectKeyed<ITest2Service>("test", ServiceLifetime.Transient)]

Your Service

public interface ITestService
{
    string Say(string message);
}

public interface ITest2Service
{
    string Say2(string message);
}

[AutoInject<TestService>]
[AutoInject<ITestService>(ServiceLifetime.Singleton)]
[AutoInject<ITest2Service>(ServiceLifetime.Scoped)]
public class TestService : ITestService, ITest2Service
{
    public string Say(string message)
    {
        return $"hello {message}";
    }

    public string Say2(string message)
    {
        return message;
    }
}
[AutoInject]
[AutoInject<ITest2Service>]
public class TestService2 : ITest2Service
{
    public string Say2(string message)
    {
        return message;
    }
}

support .net8 keyed service

//NET8.0+ 支持keyed
[AutoInjectKeyed<ITest2Service>("test2", ServiceLifetime.Transient)]
[AutoInjectKeyed<ITest2Service>(nameof(TestService2))]
public class TestService2 : ITest2Service
{
    public string Say2(string message)
    {
        return message;
    }
}

        return services;
    }
}
#pragma warning restore

Then .AddAutoInject()

• 服务将自动注册到DI容器中

// add auto inject
builder.Services.AddAutoInject();
