Unable to build on Arch Linux (possibly newer versions of mono?).

[k8ieone]

Describe the bug The build fails on Arch Linux with messages about xbuild being deprecated.

To Reproduce

1. Clone the repo on Arch Linux
2. Start the build.sh script

Expected behavior The build should finish without issues.

System information

• operating system: Arch Linux
• NBFC version: fc9fb970155607d9ebc994f9e99c8ee09121e628
• Mono version: Mono JIT compiler version 6.8.0 (makepkg/1d0d939dc30 Mon 29 Jun 2020 01:21:28 PM -03)
• Build log is below

Additional context Installing mono-msbuild and replacing xbuild with msbuild in the build script solves the problem.

nbfc package on Arch Linux doesn't actually use the build.sh script for building so it can be fixed in the AUR without touching the upstream. I already asked the maintainer to use msbuild.

This might become a problem later, when more distros update mono to newer versions.
