[[AdaCore]] took over this development in 2007, and announced "[[GNAT]] for .NET", which is a fully supported .NET product with all of the features of A# and more.<ref>Cited by Martin Carlisle (USAFA) https://asharp.martincarlisle.com/ and see also http://www.adacore.com/2007/09/10/adacore-first-to-bring-true-net-integration-to-ada/ {{Webarchive|url=https://web.archive.org/web/20071028102900/http://www.adacore.com/2007/09/10/adacore-first-to-bring-true-net-integration-to-ada/ |date=2007-10-28 }}</ref> As of 2021, A# has fallen dramatically in popularity and is considered by some to be a dead language (there are no known users or implementations).<ref>{{Cite web|last=Developer|first=Website|date=2021-03-10|title=The Mysterious Existence of A#|url=https://seattlewebsitedevelopers.medium.com/the-mysterious-existence-of-a-325d870ee6a4|access-date=2021-06-22|website=Medium|language=en}}</ref>{{Unreliable source?|date=August 2022}}
