Package: mono-reference-assemblies-4.0 (3.12.1+dfsg-2)

Mono runtime - compiler compatibility for .NET 4.0

Mono is a platform for running and developing applications based on the ECMA/ISO Standards. Mono is an open source effort led by Xamarin. Mono provides a complete CLR (Common Language Runtime) including compiler and runtime, which can produce and execute CIL (Common Intermediate Language) bytecode (aka assemblies), and a class library.

This package contains files required to compile applications against an older version of .NET, using Mono 4.0 or above, which only include the latest version of the class library as-is. This is important for producing apps for wider distribution
