Yes, VS 2012 will support CE development, including Compact Framework 3.9.  Support is scheduled to be released in Q1 of next year.  See this video for more details.

I’m (finally) trying to publish some better, more formal documentation for the ORM.  I just posted a simple example of how you can create a one-to-many relationship between Entities and how you can get the ORM to fill in the references when you do a Select call.  Take a look at the ORM documentation for more details.

I’ve just checked in new code changes and rolled a full release for the OpenNETCF ORM.  The latest code changes add transaction support.  This new release adds a load of features since the last (the last was way back in February), most notably full support for SQLite on all of the following platforms: Windows Desktop, Windows CE, Windows Phone and Mono for Android.

If you needed another excuse to try out IoC, here it is.  It’s now even easier to create intuitive UIs. I just checked in a new feature to the OpenNETCF.IoC.UI assembly.  Workspaces now have basic gesture support, so you get an even on a swipe in the four primary directions (up/down/left/right). 

The OpenNETCF ORM has supported SQLite for a while now – ever since I needed an ORM for Android – but somehow I’d overlooked addeing SQLite support for the Compact Framework.  That oversight has been addressed and support is now in the latest change set (99274).  I’ve not yet rolled it into the Release as it doesn’t support Dynamic Entities yet, but that’s on the way.
