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]

Contents

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
