A4 enabled copy_mono_root and upgraded mono to 5.16 will need to figure out what is causing this

[exts]

Workaround is to install mono 5.16 locally then renaming the GodotSharp/Mono/lib folder to GodotSharp/Mono/libx and godot will try loading mono locally from your pc. For those wanting to use latest stable

I will have a look.

So after reverting the lib folder to its original name and renaming the etc folder to something random the project builds. Here's the log file from that build.

Edit: I deleted the .mono folder just to be sure and rebuilt and here's the log file from that

I copy the mono/etc directory from a Linux install of mono. I'll figure out what the difference is between it and a windows install and fix it for a5

[neikeq]

I just checked it. There is nothing wrong with the etc folder which should be portable IINW. The problem seems to be with the bundled assemblies, concretely mscorlib. Replacing it with the one on my system fixed it.

[neikeq]

I just had a quick look and it seems the Godot binary is statically linked against Mono 5.16.0.220 while the bundled mscorlib assembly is from Mono 5.12.0.226. That would explain the problem.

Also can we update the blog to alert people so they aren't confused and maybe point to this thread for the workaround.

It's an alpha, it's fine

Most honest and accurate segment of this year

[piratesephiroth]

Replacing mscorlib fixes it partially.
The editor still can't run regular (non-mono) projects.

Fixed in beta1
