Does dependency injection potentially cause large overhead? I would imagine so, especially if the resolver is called many times (which is quite likely looking at pattern examples)? Or am I thinking wrong? Unfortunately I can't test for myself as I have never used it but planned on using it. ...
Can anyone point me at a decent repository or dependency injection library for any of the variations of Azure data services? I'm looking for quicker ways to bring applications to market and would like a library that allows (even more) minimal coding to persist and retrieve entities to the cloud.

I decided to try to conjure up a container assembly to interact with FubuMVC. Well the cool part is that it pass all the test that the FubuMVC.Container.StructureMap assembly does. However, when I dropped it into the FubuSample. I received an activation error. The error is because in the provider for the behaviors I'm only calling a par...
Can someone describe pros and cons of both methods, and when you prefer one over another? interface IService { object GetSomething(); } class Service:IService{...} DI Container.Register<IService, Service>(); class A { public A(IService service) { _service = service; } } Global class Config { publi...
I need to use some 3rd party jar in my project. The project is a Spring project and the jar is also using Spring. Is there a way by which I can include the 3rd party jar in my project? I am finding it difficult to find each and every dependency of the 3rd part jar and inject it. ...
I was just thinking that when should I actually consider loading more than one application contexts in Spring? All so far I have been merging the context files with <include> such that only one application context loads up. Do you have an idea about when to go for more than one application contexts in the same JVM? ...
I'm gearing up to jump ship at my current company in (hopefully) 9 months or so. I'm a c# developer but don't have experience past the 2.0 framework and VS2005 due to the OS limitations of our target environment. Last year we had a consultant come in for about 9 months or so and he opened my eyes to new technologies, etc.. I still kee...
I have a three layered Java application consisting of a presentation layer, a business layer, and a data access layer. In my application, the business layer contains what I am calling service classes and my data access layer contains what I'm calling data access classes. I am using Spring for dependency injection and to manage database t...
I have an object with two parameters that needs to be created via Spring.NET using the configuration file for decoupling. public Object(string param1, string param2) { ... } The two parameters are dynamically passed in based on user interaction where they pass in a username and password, so these values can't be hard coded to the conf...
I have contracts for functionality in my repository that are implemented with linq-to-sql. // IEvent was extracted from the generated linq-to-sql class public partial class Event : IEvent { } public class EventRepository : IEventRepository { public void Add(IEvent e) { db.Events.InsertOnSubmit(e); db.SubmitCha...
With regular ASP.NET MVC pages, the repository is passed in to the constructor of the control. Then the tests can instantiate the controller passing in a mock repository. How can I do this with web services? The problem I see is that we don't have the equivalent of ControllerBuilder.SetControllerFactory. What are the best practices t...
I've seen several articles on various websites that propose resolving circular dependencies between .NET assemblies by using dependency injection. This may resolve the build errors but it's not really resolving the circular dependency, is it? To me, there seems to still be a logical error in the architecture. Am I crazy or do others a...
If you don't know what I'm talking about either go through the tutorial and try to add dependency Injection yourself or try your luck with my explanation of the problem. Note: This problem isn't within the scope of the original tutorial on ASP.NET. The tutorial only suggests that the patterns used are dependency injection friendly. The...
Hello all, I've recently got a task to create a simple utility that allows to import data from a file with special format to the database. I've implemented console application with few classes(Program class operates with business logic class, business logic class in turn operates with data access class). Everything works ok, but now I'm...
Hello, I've recently asked a question regarding best ways of separating business logic from data access to make application testable (here). Thanks to Jeff Sternal, I've created interface for the data access and passing its concrete implementation from the application top level to BL. But now I'm trying to figure out how can I separate ...
Hello, Has anyone tried loading multiple hierarchical contexts (parent/child) using Spring? Could you explain how to do that as I could not locate enough documentation on this? Thanks in advance. ...
