Microsoft Patterns & Practices just released both Enterprise Library 4.0 and now Unity 1.1 this weekend just in-time for TechEd.
Unity 1.1 has a few changes and some important bug fixes:
- Removal of all obsolete ObjectBuilder code.
- Fix for a bug when using lifetime managers with open generic types.
- Fix for a bug where the RegisterType method was overriding the RegisterInstance method.
- Performance improvement when resolving singletons.
- Exposure of some additional internal classes as public to make it easier write extensions that need to resolve dependencies in a customized way.
- Addition of try...catch blocks to improve the error messages returned when value resolution fails.
