I've tried building MANY tagged versions (6 and 7) over the past few days and had 0 success getting any of them to build unfortunately =\
Also, the version of msbuild 15.5 from the AUR is busted as well. The URL no longer exists on mono-project.com. I managed to hack the PKGBUILD to pull 15.4. I don't know if that's related to my issues or not.
At this point, I don't really know what else to try. Here's a gist of what happens when I attempt to build it:
I included the output from 'pacman -Q' at the beginning so you could have a reference for the packages that I have installed. Any help that
