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][unreliable source?][4]

Examples

 Put_Line(Item => "Hello, world!");
end Hello_Dotnet;
