Microsoft’s version of dependency injection (DI) container, Unity (a.k.a., Unity Application Block) v1.1 is available for download. As you might remember 1.0 was released just back in April 2008. The documentation for v1.1 is here (VS 2005) and here (VS 2008)
To conceptually know more about DI container/IoC patterns:
The latest version of Microsoft Enterprise Library, v4.0, is finally here for download!
The most important additions in this release for me are VS 2008 support and integration of Unity dependency injection container (Unity Application Block). Go grab it!!
You know Visual Studio 2008 comes in many editions but ever wanted to know the features available with these editions? Microsoft has a comprehensive feature matrix (for quite some time) here. A downloadable copy is also available here.
If you are deciding which edition of VS 2008 to buy, then this should be your one-stop reference point.
