It is possible to use Spring.NET's aspect-oriented capabilities without using the Spring DI container? Specifically, in an app that uses Unity for IoC/DI, will Spring's AOP work?
I'm reading through http://www.springframework.net/doc-latest/reference/html/aop.html but it's quite dense and not clear to me if it requires the Spring container to be managing all objects in order to work.
Today it's not possible. Spring.Aop interact with Spring.Core and have a huge dependency of Spring.Core, the container itself.
To use AOP with Unity, you need to search about Policy Injection.
Policy Injection produces same concepts, but is limited regarding Spring.Aop.
