   Why not switch to the Microsoft version of Java (J#) and use A#?

   Conceptually, this looks very interesting.  But it says it only
   works with JDK 1.2, and is over five years old.  My best bet
   for for this project now seems to be to port the MS Visual C++
   code to g++ and call that using a normal Ada binding.

Where I can find information on A#?
Is there an official release from microsoft or is it indipendent from it?

Information is supposed to be at 
http://www.usafa.af.mil/dfcs/bios/mcc_html/a_sharp.html, but that link 
(along with others around the site) seems to be broken at the moment. 
You can Google for "Ada for .Net" and look at the cached page if the 
link stays broken.

According to an ad in the latest issue of "Ada Letters", A# is being 
welcomed into the Visual Studio .Net 2005 family (or something like 
that, I'm recalling it from memory).
