I see you found a solution, but I think I have a simpler one.

You're using Entity Framework, right? So your application almost certainly has something inheriting from DbContext (probably inheriting from IdentityContext, which in turn inherits from DbContext in this case). In the default template it's ApplicationDbContext.

In your composition root you can just add container.RegisterType(new HierarchicalLifetimeManager()); (obviously edit this if yours isn't called ApplicationDbContext).
