A Sharp (.NET)
open-in-new
<p>A# is a port of the <a href="/facts/Ada_/Y2yHel4l">Ada programming language</a> to the <a href="/facts/.NET_Framework/J6QDAUhP">Microsoft .NET</a> platform. A# is freely distributed by the Department of Computer Science at the <a href="/facts/United_States_Air_Force_Academy/LhmgXJ7b">United States Air Force Academy</a> as a service to the Ada community under the terms of the <a href="/facts/GNU_General_Public_License/S75KhLSX">GNU General Public License</a>. </p><p><a href="/facts/AdaCore/bykaAwtl">AdaCore</a> took over this development in 2007, and announced "<a href="/facts/GNAT/bykaAwtl">GNAT</a> for .NET", which is a fully supported .NET product with all of the features of A# and more. 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).[<i>unreliable source?</i>] </p>
