I'd like to have property getters and methods that I can decorate with my own custom attribute and based on the presence of that attribute replace the method bodies with a different implementation. Also, that different implementation will need to know the constructor arguments given to the custom attribute where it decorates the method.
This can obviously be done with AOP, like PostSharp or LinFu, but I'm wondering if there's a way to do this that does not involve a post-build processing step because adding that complicates the project more than I would prefer.
