StructureMap isn't creating WebAPI controllers for some reason.

Hi

I'm struggling at the moment to work out what's going on with my app.

We've recently included an owin Startup class and I believe that's what's made StructureMap stop working.

It seems like WebAPI can't create any of my controllers and I can't see StructureMap anywhere in the stack trace so that's making me think it's not registered as the controller factory or something.

"ExceptionMessage": "Type 'GRP2App.Web.API.AuthController' does not have a default constructor",
"ExceptionType": "System.ArgumentException",
"StackTrace": "
  at System.Linq.Expressions.Expression.New(Type type)
  at System.Web.Http.Internal.TypeActivator.Create[TBase](Type instanceType)
  at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.GetInstanceOrActivator(HttpRequestMessage request, Type controllerType, Func`1& activator)
  at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)"

What am I missing? There must be an OWIN config line that I'm missing that tells OWIN that StructureMap is my DI container and to use it to create controller instances

Hmm, now I've even managed to break the MVC controllers which were working fine before.

I added this to my Start.cs

config.DependencyResolver = new StructureMapWebApiDependencyResolver(IoC.Initialize());

StructureMapDependencyScope has started throwing exceptions in DoGetInstance

"Cannot access a disposed object. Object name: 'StructureMap Nested Container'."
