These annotations provide classes with a declarative way to resolve dependencies: @Autowired ArbitraryClass arbObject; As opposed to instantiating them directly (the imperative way): ArbitraryClass arbObject = new ArbitraryClass(); Two of the three annotations belong to the Java extension package: javax.annotation.Resource and javax.inject.Inject.MethodInfo mi = factory.GetType ().GetMethod ("CreateFoo"); MethodInfo generic = mi.MakeGenericMethod (type); var param = (MyBaseClass)generic.Invoke (factory, null); Where factory is the instance of IMyFactory created by Ninject and type is the type of MyBaseClass derived class I want to create.

It does not work for concrete methods. The original method is run instead. Using mockbuilder and giving all the abstract methods and the concrete method to setMethods () works.
