WPF, похоже, не существует тоже:

WPF has no investment, it’s kept together by a skeleton crew and its evangelism / community efforts have little to no funding attached to it. It’s dead, the question now is how is the corpse going to be buried and no amount of cheer leading will change that outcome in the near future.
И еще:
Evernote 4 is a major departure from Evernote 3.5 in every way. While 3.5 added tons of great new features, there were some problems we simply couldn’t fix: the blurry fonts, slow startup times, large memory footprint, and poor support for certain graphics cards were all issues that the technology behind 3.5 (Windows .net and WPF) was incapable of resolving. As a result, we ended up chasing down platform bugs rather than adding the great features our users wanted.
So we decided to start over from scratch, with fast, native C++ that we knew we could rely on. ...
On our test hardware, Evernote 4 starts five times faster, and uses half the memory of Evernote 3.5.

Насколько я понял, то, что вам нужно, в Entity Framework называется Code-First (http://weblogs.asp.net/scottgu/archive/2010/07/23/entity-framework-4-code-first-custom-database-schema-mapping.aspx).

Я про аннотирование классов, чтоб маппинг по нему строился, а не по xml. Ну в nhibernate есть. Правда если использовать в .NET nhibernate + spring.net это жава какая-то уже получается :)
