I am using Autofac and I have several classes which ask for parameter of type string and name lang. Is there a way to register a string value to all parameters named "lang", so it resolves automatically? I do not want to edit any of the constructors, since it is not my code (I know accepting e.g. CultureInfo would make registration easy..) Something resulting in short syntax like builder.Register(lang => "en-US").As().Named("lang") would be ideal. Thank you. A fairly simple way to solve this is with a custom Autofac module. First, implement the module and handle the IComponentRegistration

I'm giving a MVVMCross a spin, to see if it will be of use in some bigger projects coming up, and it's great. I like the navigation, viewModel location and general cross-platform approach, which is just what I need. However, I'm a bit stuck on splitting out some of the dependency injection depending on the platform. So, we have the basic application, with a shared portable library, that initialises the service references when starting up: public TwitterSearchApp() { InitaliseServices(); } private void InitaliseServices() { this.RegisterServiceInstance<ITwitterSearchProvider>(new

I asked a more general question a minute ago: How to organize DI Framework usage in an application? , and the feedback I got was that I was using a Service Locator Pattern rather than true DI as is pointed out by Martin Fowler here: http://martinfowler.com/articles/injection.html Actually, I read that article just the other day, but apparently haven't quite grasped it. So let's say I have the following code: interface ICardReader { string GetInfo(); void SetDebugMode(bool value); void Initialize(string accountToken); void ShowAmount(string amount); void Close(); ICreditCardInfo GetCardInfo();

I'm playing around with Ninject for a simple test-bed project at home, just to see what I can do with it. As a starting point I'm building a console runner for some service, which accepts a variety of arguments and based on what it gets in, uses the same methods provided for a fluent interface to configure a model to run. As an example, suppose I have a verbosity switch, /o . /o can be passed as /o:quiet , /o:normal , or /o:verbose . The various options are self-explanatory. To satisfy this argument I would like to attach various implementations of ILogger - quiet gets a quiet logger that

I have a class which takes an IEnumerable constructor parameter which I want to resolve with Unity and inject an array of objects. These simple classes illustrate the problem. public interface IThing { int Value { get; } } public class SimpleThing : IThing { public SimpleThing() { this.Value = 1; } public int Value { get; private set; } } public class CompositeThing : IThing { public CompositeThing(IEnumerable<IThing> otherThings) { this.Value = otherThings.Count(); } public int Value { get; private set; } } Say I want to inject four SimpleThing in to CompositeThing . I've tried several

I've been using the Spring.Net IoC container and can use it to inject properties that are of type IList and even IList<T> but I'm a bit stumped as to how to inject a property thats of type string[] . There doesn't seem to be an <array> element defined in the XSD's and using <list> <value> </list> doesn't work either. If anyone could post the xml I need to inject using an array for a property it'd be much appreciated As mentioned here in the documentation you can inject a string array as a comma delimited string (not sure what the syntax is for escaping actual commas in strings if necessary).

I'm trying to emulate a behavior that I can configure in Ninject, only using Unity instead. I am attempting to use the Cached Repository Pattern, given the following classes and interface: public interface IRepository<T> { T Get(); } public class SqlRepository<T> : IRepository<T> where T : new() { public T Get() { Console.WriteLine("Getting object of type '{0}'!", typeof(T).Name); return new T(); } } public class CachedRepository<T> : IRepository<T> where T : class { private readonly IRepository<T> repository; public CachedRepository(IRepository<T> repository) { this.repository = repository; }

I have several WebActivator.PreApplicationStartMethod decorated classes. One is for Ninject, another class for AwesomeMVC and a third one is for background task scheduler. The problem is that the scheduler class needs to take advantage of the dependecies, that are resolved by IoC container. My questions are: Can I have several WebActivator.PreApplicationStartMethod classes? Can I define order, in which they are initialized, so that IoC, being the most important, comes first? Can WebActivator.PreApplicationStartMethod static class instances rely on IoC container to resolve their constructor

I have my code which makes a webservice Call based on type of request. To do that , I have following code; public class Client { IRequest request; public Client(string requestType) { request = new EnrolmentRequest(); if (requestType == "Enrol") { request.DoEnrolment(); } else if (requestType == "ReEnrol") { request.DoReEnrolment(); } else if (requestType == "DeleteEnrolment") { request.DeleteEnrolment(); } else if (requestType == "UpdateEnrolment") { request.UpdateEnrolment(); } } } So as per open close principle, I can subclass like: Class EnrolmentRequest:IRequest { CallService(); } Class

I have a ViewModel and I want to inject another Class into it. I am using Visual Studio with the latest version of Xamarin. I'm using Autofac for registering en resolving dependencies. But I'm new to it and I'm facing a problem which I can't find the solution to, even though it's probably simple. This is the Class in which I want to inject another Class: public IMessagingCenterWrapper MessagingCenterWrapper; public LoginViewModel(IMessagingCenterWrapper messagingCenterWrapper){ MessagingCenterWrapper = messagingCenterWrapper; } Then in entry point of the app I have a function which initializes
