Unity 2.0 and Creation by Assembly

Sep 24, 2010 at 9:23 PM

I would like to use the Unity application block for dependency injection at an assembly level without having to specify every type mapping.  What I am looking for is something where either through configuration or implicitly I can specify that unity should look in Assembly X to resolve any references for interfaces defined Assembly Y.  So when I call container.Resolve<Interface>, it will look in Assembly X for the class that implements this interface.  Structure map allows the system to do this, but I haven't found a way to do so using Unity.  Is this possible?  Thanks.

There is nothing built in at this time. The reflection code required to do something like this is about 50 lines give or take, so I haven't prioritized building it. I obviously need to put something out there, I'll see what I can do.

This is really, really easy to do on top of the existing container API, assuming you know how to do reflection.

You might want to take a look at Unity Auto Registration on codeplex


I've used it as a basis for my own "register by policy" xml configuration extensions
