Hi,
I'M just trying to get started with Ninject 2 and ASP.NET MVC 2. I have followed this tutorial http://www.craftyfella.com/2010/02/creating-aspnet-mvc-2-controller.html to create a Controller Factory with Ninject and to bind a first abstract to a concrete implementation. Now I want to load a repository type from another assembly (where my concrete SQL Repositories are located) and I just cant get it to work. Here's my code:
Global.asax.cs
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
ControllerBuilder.Current.SetControllerFactory(new MyControllerFactory());
}
Controller Factory:
public class Kernelhelper
{
public static IKernel GetTheKernel()
{
IKernel kernel = new StandardKernel();
kernel.Load(System.Reflection.Assembly.Load("MyAssembly"));
return kernel;
}
}
public class MyControllerFactory : DefaultControllerFactory
{
private IKernel kernel = Kernelhelper.GetTheKernel();
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
return controllerType == null ? null : (IController)kernel.Get(controllerType);
}
}
In "MyAssembly" there is a Module:
public class ExampleConfigModule : NinjectModule
{
public override void Load()
{
Bind<Domain.CommunityUserRepository>().To<SQLCommunityUserRepository>();
}
}
Now when I just slap in a MockRepository object in my entry point it works just fine, the controller, which needs the repository, works fine. The kernel.Load(System.Reflection.Assembly.Load("MyAssembly")); also does its job and registers the module but as soon as I call on the controller which needs the repository I get an ActivationException from Ninject:
No matching bindings are available, and the type is not self-bindable.
Activation path:
2) Injection of dependency CommunityUserRepository into parameter _rep of constructor of type AccountController
1) Request for AccountController
Can anyone give me a best practice example for binding types from external assemblies (which really is an important aspect of Dependency Injection)? Thank you!
