I'm starting to work with StructureMap on a windows application project. In working on learning the basics, I found 2 ways to arrange my solution that accomplish the same goal, and I'm wondering if anyone can comment on if one of these 2 seems like a better option, and why. The goal here was to use IOC so that I could use 2 services without taking dependencies on them. So I I created interfaces in my Business Layer, and then implemented those interfaces in my Infrastructure project and wrapped the actual services at that point. In my fist attempt at this, I created a project DependencyResolver

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 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'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 using MVC 3 and using the following code when the application starts... UnityContainer container = new UnityContainer(); new UnityMappings(container); DependencyResolver.SetResolver(new UnityServiceLocator(container)); Now when the app runs I'm getting the following error (but only sometimes)... Activation error occured while trying to get instance of type IControllerFactory, key "" Interestingly, if I continue with the web request, the website works normally. Any ideas? I can't see what I'm doing differently from before when this worked fine. Cheers, Ian. MVC3 requests a lot more than

I ran into an issue that can only be explained with my fundamental lack of understanding of Spring's IoC container facilities and context setup, so I would ask for clarification regarding this. Just for reference, an application I am maintaing has the following stack of technologies: Java 1.6 Spring 2.5.6 RichFaces 3.3.1-GA UI Spring framework is used for bean management with Spring JDBC module used for DAO support Maven is used as build manager JUnit 4.4 is now introduced as test engine I am retroactively (sic!) writing JUnit tests for the application and what suprised me is that I wasn't

I'm using the Simple Injector IoC framework, and I would like to be able to change the dependency registration at run time. For example, I have two implementations, A and B , of interface I . Implementation A is registered at app start, but depending on some flag which can change during runtime, I would like to switch the implementation. We are currently doing this the OnActionExecuting event of our BaseController , which all of our controllers inherit from. Here is the sample code of what I am trying to do. protected override void OnActionExecuting( ActionExecutingContext filterContext) { if
