Castle Windsor with ASP.NET MVC 2 Areas
- by Doug Shontz
Been lurking for a few months and decided to jump in with a question. I am very new to Windsor and IoC in general. I can get Windsor to work with my MVC2 project with no problem. The project I am working on is a "portal" of multiple applications under one MVC2 project using the new Areas concept. In this scenario, each Area will actually be a separate application inside the "portal". We are doing this to effectively share a LOT of common code, views, authentication, and cross-application functionality. Many of our apps link to one another, so it made sense after discussing it to combine them into one project.
What I am wondering how to do is actually allow different Areas to inject different concrete classes? In my limited understanding, the Application_Start is governing building the container and assigning it as the controller factory. I don't necessarily want to do all the injection at the application level. We have a config system where we have a config.xml at the root of every Area and those settings override any root settings. I would like to continue that trend by having the injections for each Area be read by the Area's config.xml (an inheritance similar to Webforms web.config where the config in a lower folder overrides settings in a parent folder).
Example: I would have an ILogHandler which would need a different concrete implementation depending on which Area of the application I am in. So I would need to inject something different depending on where I am at in the application.
I can easily do this using factories since each area could have it's own set of factories, but I am attempting to take this opportunity to learn about IoC and what the benefits/drawbacks are. Any help would be appreciated.
