Aug 6, 2010I will like to add Rhino Service Bus to my ASP.NET web application but using Ninject as the DI Container. So far all examples I keep seeing use Castle Windsor which I don't want to use since we already use Ninject.Are there any tutorials out there which show how to add Rhino Service Bus to an ASP.NET web application without a direct dependency on Castle Windsor (e.g. using Ninject)?

C# : Dependency Injection And Roles?
Jul 20, 2010I have a page using an injected BLL service: a simple service returning a set of objects with a function like this:
public IMyService { List<Foo> All(); }
There is a default implementation for normal users.Now, i need that users in administrative role can view more objects, with another implementation of the service.Where can i configure my page to use the second implementation?
My first solution is to put the dependency to the IUnityContainer in the page, and use it to resolve the dependency:
[Dependency]
public IUnityContainer Container { get; set;}
Page_Init(..) [code].....
it's a ServiceLocator and it's neither scalable neither testable.
C# - .NET Module Dependency Injection?
Jan 3, 2011During the design of a new generic authentication framework for some of our products, I have come across an architectural issue I cannot seem to find a good solution for.I have tried to simplify the problem in order to easily explain it.
The library has two classes:
Manager Is responsible for storing currently authenticated users.Module It is the responsibility for the module to validate each request according to security policies. The Module must ask the manager to determine whether a user is currently authenticated.
Now the manager is supplied an implementation of an interface which allows the manager to load users from a repository. The specific implementation is not contained in this library. Because of this, I cannot directly instantiate an instance of the repository within the library.
I have no way of modifying properties or supplying arguments for the module constructor. So my question is this, how can I give the module a reference to an instance of the Manager?

public interface IRepository

View 1 RepliesMVC :: ModelBinder For Dependency Injection On ViewModels?
Jan 25, 2011This project is pretty far away and I'm not in the position to go make changes all over the place (If I could, deleting the lot would be what I'd do!)
I want to create a modelbinder that would resolve any dependencies my View Models might have (using StructureMap).
It should not require me to implement a specific interface (so many developers, so many interfaces..I rather keep things clean) and hopefully not require one to go register each model binder individually (Now I'm asking too much,taking the first requirment
in consideration).
Probably will get it right tonight, but figured I'd ask.
C# - Dependency Injection - Colloquial Explanation
Apr 8, 2010Recently I was asked to express the DI in colloquial explanation.
I answered :
1)I am going to a hotel.I ordered food.The hotel management asks me to clean the plates and
clean the tables.So here i am a client,I am responsible for managing the service (Instantiating,executing,disposing).But DI decouples such tasks so the service consumer no need not worry about controlling the life cycle of the service.
2)He also asked is there any microsoft API follows DI ?.I answered (This was my guess) In WCF you can create a Proxy using ChannelFactory that controls the life time of your factory.
for item (1) he said only 10% is correct
for item(2) he said that is factory pattern not dependency injection.
Actually what went wrong in my explanation (apart from my bad English) ? What is the real answers for those?
C# - What Dependency Injection Framework With WebForms
Nov 27, 2010I have been looking at learning dependency injections (i think i have now grasped the basics) and am looking to implement it into a webform application. My question is, what dependency injection framework should i use for a webforms project, or is it a question of what works best for you?
I Have currently looked at Spring.Net, Ninject, Unity and StructureMap, i tend to have no preference in the configuration, whether its XML or fluent interfaces. However is XML configuration becoming less favourable?
Most of the information i come across relates to dependency injection whilst in a MVC environment. And have also read that some frameworks such as Structure Map only work with webforms using version 2.0 or earlier. So the kind of things i need to consider are whether webforms will be continuous support, and the ease of configuration for someone relatively new to the pattern.

LINQ Statement Vulnerable To SQL Injection?
Sep 29, 2010Is this LINQ statment vulnerable to SQL injection?
var result = from b in context.tests
where b.id == inputTextBox.Text
select b;
where context is an Entity and tests is a table. I'm trying to learn LINQ and I thought that the benefit of it was that it wasn't vulnerable to sql injection, but some stuff I've see has said differently. Would I need to parametrize this LINQ statement to make it safer? If so, How? Also would this be considered linq to sql or linq to entities?

.net - What's The Point Of Dependency Injection Frameworks
Aug 12, 2010I am sure that I am somewhat lost in this area... my understanding is that Dependency Injection means initializing something that is required by a class..so for instance. If my controller is going to need a service and I want to be able to test it then I should define two Constructor methods for it... so, my question is.
public class CompaniesController : Controller
{
private ICompaniesService _service;
public CompaniesController()
{.......
MVC :: Dependency Injection / The Role Of A 'Model'?
May 27, 2010My general understanding of the MVC pattern is that the model is reponsible for persisting itself. Though I also see other opionions that models should be dumb data objects and that controllers should persist them via a data access layer.
Per http://en.wikipedia.org/wiki/Model_view_controller: "Many applications use a persistent storage mechanism such as a database to store data. MVC does not specifically mention the data access layer because it is understood to be underneath or encapsulated by the model." Though it does also mention "Models are not data access objects."
Per http://www.asp.net/mvc/tutorials/asp-net-mvc-overview--cs, "Models. Model objects are the parts of the application that implement the logic for the applications data domain. Often, model objects retrieve and store model state in a database. For example, a Product object might retrieve information from a database, operate on it, and then write updated information back to a Products table in SQL Server."
First, am I misguided in believing that models should persist themselves? Or, is this just a matter of opinion?
Second, if I follow the pattern where controllers manage the persistence of the model, I find it fairly easy to use dependency injection to inject a data access component into my controller using a custom controller factory (implementing the IControllerFactory
interface). If I follow the pattern where my model saves itself, I'd want to inject my data access component into the model. Is there a way to provide a custom factory for models? Otherwise, I don't think using DI with models is possible.
Dependency Injection And Code Maintainability?
Oct 30, 2010I am working on a (vb.net/asp.net) project that is using interfaces to provide dependency injection. But to me, it feels like the maintainability of the code has been killed. When I want to read through the code, I can't simply jump to the code of a related class that is used. All I see are the interfaces, and so I have to hunt through the project to figure out what classes are doing the implementation. This really hurts my productivity.
Yes, I know I now can implement the interfaces with a wide variety of replacement classes. But for example, I know I'm not changing my data source any time soon--there is no need for me to enable the ability to swap that out. All of this dependency injection seems like overkill to me (in fact, the only real reason it is there is to support mock classes for unit testing). I've actually read several places that state DI is actually better for maintainability. But that assumes you already know where everything is and you know which class you need to update. Finding out where to look is the part that is killing me. So, my question is: Is there a better way to traverse through the code? Is there a better way to make the code more maintainable? Are we just doing it wrong? Or is this par for the course?
Storing HTML In Db While Avoiding Persistent Xss / Sql Injection?
Nov 29, 2010I'm building a page in asp.net that will use tiny mce to provide a rich text editor on the page. Tiny mce outputs the rich text as html which I would like to save to a database. Then at a later date, I want to pull the HTML from the database and display it in a page.
I'm concerned about allowing malicious html, js tags into my database that would later be output.
I should html encode/decode etc. to prevent a persistent xss attack and or sql injection attack?
