Respectfully bumping this since it would truly be awesome to have a more recent version of mono in the ports tree to benefit from the latest performance improvements and bug fixes.

@cem Hi there! Is there a link to the v2 ?

Yes. Please bring plumbing supplies and a snowblower :-)

Is there something we can do to help move this work forward?

We tested this patch, the mono runtime seems to work fine to run existing applications, however there are missing build tools. We are among the many people using mono as a development environment using the tools included in the mono package (msbuild, the csharp interactive interpreter etc...). To be specific, the exact error we got when trying to build a csharp application was that the folder /usr/local/lib/mono/msbuild/15.0/bin/Roslyn/ is missing - along with all the files this folder is supposed to contain.

If there is something we can do to accelerate the merging, please let us know. We are in the process of migrating all our workstations to FreeBSD, but the lack of a recent mono version is blocking and so critical that we may have to move to Linux instead, this would be a shame. A recent mono is indeed now required to have a development environment for csharp on Unix (omnisharp-roslyn requires mono version 6.4.0 at least. For context: omnisharp-roslyn is the backend providing IDE-like features for csharp to all text editors).

Is anyone working on this?
