The convention based registration works great for us, and it is of great value I believe.
However I do get a slow startup time, because of repeatedly iterating over the assemblies' GetExportedTypes collections, once for MR components, once for the convention configurations, and more. what could be great is some kind of a way to hook into a single iteration over an assembly types collection, and supplying an action for every one (if it's a MR controller/filer/etc, if it's a Service that implements IService, etc.) 2010/1/21 Krzysztof Koźmic (2) <[email protected]> > Alvin, > > Problem is this approach won't work when matching constructor > parameters, and it changes semantics of the dependencies. > > when you specify just a name with string, you're being implicit about > what kind of dependency it is (property or method argument) and let > Windsor figure it out. > Indeed depending on which constructors Windsor can satisfy, the same > call can lead to having the dependency injected as ctor arg, and other > time as property. > > I think it's a great strength of Windsor, and I much dislike being > explicit about it when dealing with some other containers.
