Castle Windsor + ASP MVC 5 - System.MissingMethodException: Cannot create an instance of an interface

Question

First of all, sorry for my english. I am trying to do something small in windsor + mvc. I read some tutorials, and look for any solution of my problem, but i haven't found any. Use:

• VS 2013 Express
• ASP MVC 5.2.2 (.net 4.5)
• Castle.Windsor 3.3.0 for .NETFramework v4.5

I want to build a modular app (web + domain + db layer), but i still get error:

Exception Details: System.MissingMethodException: Cannot create an instance of an interface.

Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

..............

Main class or function of my app ( right now all in the same module/dll .web )

public class HomeController : Controller
{
    public ActionResult Home(ITestApi test)
    {
        var result = test.Test();

        return View();
    }
}

ITestApi Interface

namespace Dashboard.Web.Services.Interfaces
{
    public interface ITestApi
    {
        string Test();
    }
}

TestApi Class

namespace Dashboard.Web.Services.Implementation
{
    public class TestApi : ITestApi
    {
        public string Test()
        {
            return "test";
        }
    }
}

in Global.asax

 private static void BootstrapContainer() {
                Container = new WindsorContainer();
                Container.Install(FromAssembly.InThisApplication());            
                // Create the Controller Factory
                var castleControllerFactory = new WindsorControllerFactory(Container);
                // Add the Controller Factory into the MVC web request pipeline
                ControllerBuilder.Current.SetControllerFactory(castleControllerFactory);
            }

installer

public class WebInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(
                Classes.FromThisAssembly()
                .BasedOn<IController>()
                .LifestyleTransient()
                );

            container.Register(
                Classes.FromThisAssembly()
                .BasedOn<ITestApi>()
                .LifestyleTransient()
                );
        }
    }

I have tried a few different method for register TestApi class, but the result is always the same.

container.Register(
                Classes.FromAssemblyInThisApplication()
                .InSameNamespaceAs(typeof(ITestApi))
                //.WithServiceDefaultInterfaces()
                .WithService.DefaultInterfaces()
                .LifestyleTransient()
                );

Could anyone help me ?

Answer 1

I am not sure, but i think you are just registering all Classes who are using ITestApi against their own name, but you never say what class should be used when CastleWindsor should inject a ITestApi

Replace your

     container.Register(
            Classes.FromThisAssembly()
            .BasedOn<ITestApi>()
            .LifestyleTransient()
            );

with the C# version of this (Sorry, having only a VB.NET snippet)

container.Register(Component.For(Of ITestApi).ImplementedBy(Of TestApi).LifestyleTransient())
