mono-xbuild binary package in openKylin Nile V2.0 arm64

 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.
 .
 xbuild is Mono's implementation of msbuild and allows projects that have a
 msbuild file to be compiled natively on Linux.
 .
 Microsoft Build (msbuild) is a build system developed by Microsoft similar in
 spirit to Nant (in that it uses XML files for describing the build process)
 and in the same spirit as make.
