Ninject ToFactory works in Resharper unit tests, but not NCrunch

Question

I'm using Ninject.Extensions.Factory with Ninject 3 to create a factory, which creates different types of IFoo based on the string provided to the factory. I've got a passing unit test, but oddly, only in the Resharper test runner. In the NCrunch test runner it fails. Is this a NCrunch config issue, or do I need to change the code?

The interface:

public interface IFooFactory
{
    IFoo CreateFoo(string name);
}

The Ninject bindings:

kernel.Bind<IFooFactory>().ToFactory(() => new UseFirstParameterAsNameInstanceProvider());
kernel.Bind<IFoo>().To<BarFoo>().Named("Bar");

The test:

[Test]
public void CanCreateFooTest()
{
    var factory = (IFooFactory) Kernel.GetService(typeof(IFooFactory));
    var bar = factory.CreateFoo("Bar");
    Assert.AreEqual(typeof(BarFoo), bar.GetType());
}

And the NCrunch exception:

System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation.
  ----> Ninject.ActivationException : Error activating IInterceptor using conditional implicit self-binding of IInterceptor
Provider returned null.
Activation path:
  2) Injection of dependency IInterceptor into parameter  of constructor of type IFooFactoryProxy
  1) Request for IFooFactory

Suggestions:
  1) Ensure that the provider handles creation requests properly.

Answer 1

Go into the NCrunch configuration for the unit test library and set Copy referenced assemblies to workspace to True.

Answer 2

Here the code that works with NCrunch:

        var kernel = new StandardKernel();
        kernel.Bind<IFooFactory>().ToFactory(() => new UseFirstParameterAsNameInstanceProvider());
        kernel.Bind<IFoo>().To<BarFoo>().Named("Bar");
        kernel.Load<FuncModule>();

        var factory = kernel.Get<IFooFactory>();
        var bar = factory.CreateFoo("Bar");
        Assert.Equal(typeof(BarFoo), bar.GetType());

UPDATE

This works great, and sorts out NCrunch. However, Resharper complains that it has been loaded twice. The workaround:

    #if NCRUNCH
        Kernel.Load<FuncModule>(); 
    #endif

Answer 3

The FuncModule is not loaded when running with that TestRunner. This happens in case the extension is not copied to the startup directory of the executed process.

I don't NCrunch. So I can't tell you what it is doing. But most likely it copies the assemblies in a different way than the R# test runner. You could load the extensions manually but this feels like a hack.
