Not sure how to register controller and repository correctly

[bioluminescence]

Hi,

I am using MVC 2 and I am new to Autofac. I'm not sure what I am
doing wrong, I know it is something. I want to register my
controllers and repository.

My NewsController constructor receives an INewsRepository parameter.
NewsPository implements INewsRepository. How would I register this?
This is what I currently have (I know it is wrong):

var builder = new ContainerBuilder();
builder.RegisterControllers(Assembly.GetExecutingAssembly());
builder.Register<NewsRepository>().As<INewsRepository>().SingletonScoped();

The compiler error is: No overload for method 'Register' takes 0
arguments

I assume that I am doing it wrong in registering all the controllers
as once like I did seeing that the NewsController constructor requires
a parameter?

Please can someone help me with the correct code?

Thanks
Brendan

Hi,

The method you're looking for is RegisterType(), e.g.:

  builder.RegisterType<NewsRepository>()

Cheers,

Nick

You want to use builder.RegisterType<NewsRepository>(). Use the builder.Register<T> method if you want to handle construction of the object a bit more custom, ie:

builder.Register<NewsRepository>(x => new NewsRepository(SomeMethodToGetConfig(()).As<INewsRepository>()

Hi,

Thanks. Isn't this where I tell it to inject NewsRepository for
INewsRepository? By using builder.RegisterType<NewsRepository>() how
would it know to inject NewsRepository for INewsRepository?

Hi Brendan,

The same configuration syntax works - 

   builder.RegisterType<NewsRepository>().As<INewsRepository>();

The method you're using, "Register(Type)", was renamed in v. 2.0 to: "RegisterType(Type)".

Will be sufficient?

var builder = new ContainerBuilder();
builder.RegisterControllers(Assembly.GetExecutingAssembly());

builder.RegisterType<NewsService>().As<INewsService>();

So as I understand it, where ever INewsService is used (like in my
example in the controllers constructor) NewsService will be injected?

I tried to implement it in my previous email, but then I get an
error. I am using MVC 3 with the assemblies that were loaded on 16
October. Can this be the reason why? I don't know how to get the
latest build for MVC 3. I don't understand the client software, too
complicated:

None of the constructors found with 'Public binding flags' on type
'Nedbank.Recognition.Core.Services.NewsService' can be invoked with
the available services and parameters:
Cannot resolve parameter
'Nedbank.Recognition.Core.Repositories.INewsRepository newsRepository'
of constructor
'Void .ctor(Nedbank.Recognition.Core.Repositories.INewsRepository)'.

Thanks.

Just another question. How would I register a specific controller
that received a specific parameter? My controller looks like this, so
I will need to specify the parameter some how:

public NewsController(INewsService newsService)
{
this.newsService = newsService;
}

In this case do I need to register the controller individually, or
should I still register it all together?

Register it all together - the default behaviour is what you're after.

BTW, Stack Overflow (we have an Autofac tag over there) is generally a better place for basic usage questions as answers over there are easier for others to find via Google. There's also less moderation delay :)

Good luck!
