In Simple Injector v3.0 we will break with the past. We will remove legacy methods, considerably simplify parts of the API, and add new compelling features.

We will strive to let the API guide users as much as possible about any breaking changes. This means that removed parts of the API, will physically still exist, but will be marked with [Obsolete(error: true)] attributes with expressive messages that explain what to call instead. This will make it easier for users to migrate from v2.x to v3.0. We are planning to eventually remove those methods somewhere after v3.0.
