Question

Why should I prefer StructureMap over Unity?

Answer 1

StructureMap allows you to register your types by convention. Instead of explicitly registering Foo for IFoo, Bar for IBar, and Baz for IBaz, you can do:

ObjectFactory.Initialize(x => 
  x.Scan(scan => {
    scan.TheCurrentAssembly();
    scan.WithDefaultConventions();
  })
);

The "Default Standard" automatically registers every type that has an interface with the same name and prefix "I". There are a few more built-in conventions (if you type names, don't follow this pattern), and it is trivial to define your own.
