Is it possible to inject beans into inner class? For example: @Named public class outer { @Inject private SomeClass inst; // Injected correctly private static class inner { @Inject private AnotherClass instance; // Not being injected ... Edit: The "AnotherClass" is used only by inner class, so I do not want to pollute outer class with it. Additional reason to keep the declaration in the inner class is that I'll have to remove the static modifier from the inner class or add it to the outer class member if I move the AnotherClass member to the outer class. Annotations like @Inject are used only

I'm using Unity IoC (Microsoft.Practices.Unity) and I can compile fine, but I'm getting the following error at run time: Could not load type 'System.Reflection.IntrospectionExtensions' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The Unity version is: 3.0.1026.0 Is there a compatibility problem between .Net 4 and this version of Unity. Also, I get the same error when using Unity v2. If so, how might I go about resolving this issue? EDIT: Also, I've verified that mscorlib is referenced in my project. RESOLVED. Indeed I was using the .NET 4.5

I currently use Autofac to do simple constructor injection without any issues. However what I would like to know is how to resolve dependencies at runtime. The example below shows multiple ways in which we can export a document. With simple constructor injection the concrete implementation of IExport is resolved at runtime. However what need to do is to resolve IExport on a user selection from a dropdown list which will happen after the construction of my container. Is there any examples of how I can achieve this? Public interface IExport { void Run(string content); } public class PDFformat :

I have a controller and it receives a specific instance of an interface. The interface looks something like this: public interface IMyInterface { ... implementation goes here } And then I have some classes that implement this interface like this: public class MyClassA : IMyInterface { ... implementation goes here } public class MyClassB : IMyInterface { ... implementation goes here } In my ControllerA I have the following constructor: private ICustomerService customerService; private IMyInterface myInterface; puvlic ControllerA(ICustomerService customerService, IMyInterface myInterface) { this

I have a simple filter. public class IsAdmin : ActionFilterAttribute, IAuthenticationFilter { private string _roleName; IBusinessIdentity _identity; public IsAdmin(string roleName, IBusinessIdentity identity) { this._roleName = roleName; this._identity = identity; } public void OnAuthentication(AuthenticationContext filterContext) { } public void OnAuthenticationChallenge(AuthenticationChallengeContext filterContext) { if (!_identity.Roles.Contains(_roleName)) filterContext.Result = new HttpUnauthorizedResult(); } } I am using Ninject. Here is my controller. I'm trying to get the injected

I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC. For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception. If I force garbage collection the memory is released OK. My datacontext class is very simple: public class DataContextAccessor : IDataContextAccessor { private readonly DataContext dataContext; public DataContextAccessor(string connectionString) { dataContext = new
