Supported containers

MR.AttributeDI.ServiceCollection

Microsoft's IServiceCollection

MR.AttributeDI.Autofac

Autofac

Example using IServiceCollection

[AddToServices(Lifetime.Transient)]// This will register DefaultMath as self[AddToServices(Lifetime.Transient,As=typeof(IMath))]publicclassDefaultMath:IMath{publicintAdd(intx,inty){returnx+y;}}

usingMR.AttributeDI.ServiceCollection;services.ConfigureFromAttributes(typeof(Program).GetTypeInfo().Assembly);// Assemblies to search in

And then simply:

provider.GetService<IMath>();provider.GetService<DefaultMath>():

Using tags

[AddToServices(Lifetime.Transient,Tags="foo")]publicclassDefaultMath
...

Here, DefaultMath won't be registered unless we specify its tag in configuration:

services.ConfigureFromAttributes(typeof(Program).GetTypeInfo().Assembly);// Will not register DefaultMathservices.ConfigureFromAttributes("foo",typeof(Program).GetTypeInfo().Assembly);// Will register DefaultMath

Multiple tags can be specified separated by a comma (for example "default, integration").

Forwarding

You can also forward service registrations for services where you want to share a single instance for multiple interfaces:

[AddToServices(Lifetime.Singleton,As=typeof(IFoo))][AddToServices(Lifetime.Singleton,As=typeof(IBar),ForwardTo=typeof(IFoo))]publicclassSomeService:IFoo,IBar{}
