7 years ago Give or take, this should decrease startup time by 500ms if we apply it in MonoDevelop, but it can lead to hard to track bugs. I'm still not sure what to do about this PR. We reflect a lot just to register a gtype.
Most managed implementations in MD do not have any kind of Property/Signal/Interface usage. So we can trim down assemblies so native registration is skipped for the types that contain them.
The problem is do we want that?
This attribute allows for a fast path of registration of a gtype. We selectively choose what to register if we mark the type with the attribute. Thus, if you mark something with IgnoreRegistration(DefaultHandlers=false), it'll only register DefaultHandlers for a method, so we don't reflect all the methods of each type when we register the gtype.
