Rayson.DependencyInjection 1.0.4

Rayson.DependencyInjection? Why...?

With absolutely zero setup, you can start writing code that uses dependency injection. There's no need to manually configure a container. I have always felt that having to write a configuration file for DI is so much hassle, and really isn't needed. The API is designed to be as thin and as easy as possible, while still providing some flexibility. Convention over Configuration!!

Get started guide

Using the Container class

The static Container class contains static methods for instantiating objects and automatically resolving their dependencies. The resolution of the dependencies will store those dependencies in a cache ready for next time.

Getting a New Instance of an object

Interface obj = Container.ResolveInstance<Interface>();
// or
Class obj = Container.ResolveInstance<Class>();

Getting a Singleton

Interface obj = Container.ResolveSingleton<Interface>();
// or
Class obj = Container.ResolveSingleton<Class>();

Getting all possible components

IEnumerable<Interface> obj = Container.ResolveMany<Interface>();
// or
IEnumerable<Class> obj = Container.ResolveMany<Class>();

Getting a specific implementation

MySpecificClass obj = Container.ResolveSingleton<Interface>(nameof(MySpecificClass));

Implementing your own container

You may implement the IContainerAdapter interface in any way you like, and then set the static Container class's internal instance by calling...

Container.SetCurrent(yourCustomImplementation);

...All calls to Container methods will then use your custom implemenation. This gives you the freedomt to use any other DI framework under the hood.

Any gotchas?

Maybe... Just Try It! I promise you it'll be faster to start with than any of the major DI frameworks, I've tried most of them...

Why isn't my dependency being found?

You will need to have your dependency assemblies in the same location as the class you're trying to resolve, this is where the DefaultContainer will search for assemblies and load them in. For example, if you resolve a class from an assembly which is in the "C:/MyLocation/Assemblies/" folder, all of the dependencies of that dll will need to also be in that folder.

Can I load a DotNet type?

YEP! But it's not thoroughly tested, so it may not work for everything. You can certainly get a DotNet Dictionary<T,T2> but other classes have not been tested. I'm pretty sure String would fail because it doesn't have a constructor, for example.

Do you have a test suite?

Of course I do! There's a total of 24 sanity tests at the moment, and growing with every new feature I add. There shouldn't ever be something that works in one version that gets broken in a subsequent version, but bad things happen... If you ever find a bug, please report it to danrayson@hotmail.co.uk and I'll let you know when it's fixed.
