No registration for type IEnumerable<IFilterProvider> could be found.

[bjm3819]

Updated from SimpleInjector 3.0.0 to SimpleInjector 3.0.1 is breaking the MVC web site.
There are several types that are not getting registered such as IEnumerable<IFilterProvider> and IEnumerable<ModelValidatorProvider> , etc.

[dotnetjunkie]

Please update to the SimpleInjector.Integration.Web.Mvc NuGet package version 3.0.2.

[bjm3819]

My configuration looked like the below after upgrading and that is when stuff broke and I rolled back.
"SimpleInjector" version="3.0.1" targetFramework="net45"
"SimpleInjector.Integration.Web" version="3.0.1" targetFramework="net45"
"SimpleInjector.Integration.Web.Mvc" version="3.0.2" targetFramework="net45"

My current working configuration is (below)
"SimpleInjector" version="3.0.0" targetFramework="net45"
"SimpleInjector.Integration.Web" version="3.0.0" targetFramework="net45"
SimpleInjector.Integration.Web.Mvc" version="3.0.0" targetFramework="net45"

so I'll try to upgrade to the SimpleInjector.Integration.Web.Mvc NuGet package version 3.0.2

[bjm3819]

so after updating as you suggested the problem comes back to life. Image attached.

[dotnetjunkie]

I just double checked by pulling in version 3.0.2 of the SimpleInjector.Integration.Web.Mvc NuGet package, but the problem is really solved in that version. If I roll back to 3.0.1 the problem reappears again.

I expect that somehow an old version is cached on your machine. Make sure that the project references version 3.0.2 (you can check this by going to properties after right clicking on the assembly in the project's references list).

[utkuerd]

Upgrading to 3.0.3, my MVC project generated a similar error. Do you think the problem came back?

[dotnetjunkie]

Can you post a full stack trace of the exception and inner exceptions?

[dotnetjunkie]

@bjm3819, you are using your own custom IDependencyResolver implementation called PMD.Web.Http.SimpleInjectorWebApiDependencyResolver. This implementation is calling GetAllInstances. The behavior of GetAllInstances has changed in Simple Injector 3.0.

Please use the SimpleInjectorWebApiDependencyResolver class that is provided by the SimpleInjector.Integration.WebApi NuGet package, or change the GetServices method of your custom implementation to the following:

IEnumerable<object> IDependencyScope.GetServices(Type serviceType) {
    Type collectionType = typeof(IEnumerable<>).MakeGenericType(serviceType);
    var services = (IEnumerable<object>)this.ServiceProvider.GetService(collectionType);
    return services ?? Enumerable.Empty<object>();
}

@utkuerd, are you using your own custom implementation as well?

[utkuerd]

Ok, here is some more detail for my case:

I was at 2.5.2 and upgraded it to 3.0.3. I do not have a custom IDependencyResolver implementation. I'm using SimpleInjector with ASP.NET MVC 5.2.0. (Tried upgrading it to 5.2.3 too, same result). There seems nothing related to my code in the stack trace.

I've also applied your workaround at #98 and it was a success. After inserting
container.Options.ResolveUnregisteredCollections = true; problem disapeared. But my container is not empty. I've registered some dependencies. Am I missing something?

Here is my exception details:

SimpleInjector.ActivationException occurred

There seems nothing related to my code in the stack trace.

@utkuerd, there actually is something related to your code in the stack trace, but you have to know what to look for. Here is the clue:

System.Web.Mvc.DelegateBasedDependencyResolver.GetServices(Type type) +47

The DelegateBasedDependencyResolver is used everytime you register a resolver either using System.Web.Mvc.DependencyResolver.SetResolver(object) or SetResolver(Func<Type, object>, Func<Type, IEnumerable<object>>).

In other words, you are either calling:

DependencyResolver.SetResolver(((IServiceProvider)container).GetService, container.GetAllInstances)

or you are calling:

DependencyResolver.SetResolver(container);

Both are not valid in Simple Injector 3 anymore. The call SetResolver(object) expects to get supplied with a type that contains both a GetInstance and GetAllInstances method. Although Simple Injector 3 contains both methods, GetAllInstances does not match the expectations of MVC, because MVC expects that method to return an empty collection in case no collection is registered. For that same reason, SetResolver(..., container.GetAllInstances) breaks. You will have to change that call to the following:

DependencyResolver.SetResolver(((IServiceProvider)container).GetService, 
    type => (IEnumerable<object>)container.GetService(typeof(IEnumerable<>).MakeGenericType(type))
        ?? Enumerable.Empty<object>());

[utkuerd]

Thanks for clarificaton. I had suspected something breaking down with my v 2.x style use of DelegateBasedDependencyResolver, but I couldn't have figured out how things bind together by examining stack trace. That cleared everything.

A quick question from my curiosity, any plans to provide a mechanism to automatically adapt the new behavior of Container to MVC? For example in the SimpleInjectorDependencyResolver class in MVC Integration package?

[dotnetjunkie]

@utkuerd: The SimpleInjectorDependencyResolver of the SimpleInjector.Integration.Web.Mvc NuGet package v3.0.2 (and up) adapts to the new behavior of the container, while adhering to the IDependencyResolver contract. So it's best to use the integration package.

[utkuerd]

Oh great, I'll go that way. Thanks for the answers.

[dotnetjunkie]

Fixed in v3.0.2.

[dotnetjunkie]

@jabreuar, what IDependencyResolver did you register? Can you show the code to reproduce?

[anakic]

I'm having the same issue as @jabreuar. My registration is extremely simple:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    //IOC
    Container container = new Container();
    container.Register<IIdentityProvider, LoggedOnUserIdentity>();
    DependencyResolver.SetResolver(container);
}

[anakic]

Woops, I figured out my problem. The last line is supposed to be:

DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));

I wonder why the compiler let me pass the container object, it doesn't implement IDependencyResolver as far as I can see.

[dotnetjunkie]

I wonder why the compiler let me pass the container object

The MVC designers tried to be smart and implemented some sort of duck typing. When the supplied object contains a GetInstance and GetAllInstances method, MVC will simply call those methods using reflection. Yuck.

In Simple Injector v3 however, the behavior of GetAllInstances changed. We now stop returning unregistered collections, but throw an exception instead. This is why you should use the SimpleInjectorDependencyResolver instead of passing in the container object.

[anakic]

Yeah, it's very strange. Global.asax, in general, has some crazy dynamic compilation magic going on.
