A Sharp (.NET)
A# is a port of the Ada programming language to the Microsoft .NET platform. A# is freely distributed by the Department of Computer Science at the United States Air Force Academy as a service to the Ada community under the terms of the GNU General Public License. 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. 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). Examples

hello world
with Ada.Text_IO;
use Ada.Text_IO;
procedure Hello_Dotnet is
begin
 Put_Line(Item => “Hello .NET world!”);
end Hello_Dotnet;
