A Sharp (.NET) explained

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.^[1]

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.^[2] 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).^{[3] [4]}

Examples

Hello, world!

with Ada.Text_IO;use Ada.Text_IO;procedure Hello_Dotnet isbegin Put_Line(Item => "Hello, world!");end Hello_Dotnet;^[5]
