The April 2008 release of the Smart Client Software Factory is now available at http://msdn2.microsoft.com/en-us/library/aa480482.aspx

This is a port of the last release (May 2007, if I recall correctly) to VS2008.  No new features were added.  A few bugs were fixed, and a number of work items from CodePlex were closed.

This release supports Enterprise Library 3.1.  It does not support Enterprise Library 4.0.  If you want EntLib 4.0 (once it is released) you have the source code, and should be able to get it to work, if you really need to.  I would not recommend it, as you will end up with two containers (Unity and the CAB container), which means code bloat and challenges deciding where objects should go.
