the problem is that mscorlib.dll is no longer portable and needs to be built for each platform. This will also give us some other headaches as well. I’m working on a way to fix this properly but it’s not entirely trivial.

mono.zip

Compiling from windows 10/vs build tools 2017 (which works fine) built against mono 6.6.0 (official), that’s the GodotSharp/Mono/etc/mono folder with all the configs in there. Maybe there’s something in there that isn’t in the existing config which is causing the issue?

Edit: Another thing I noticed is my local windows build has the libmono-btls-shared.dll while the one you provided doesn’t.

Building the editor from source using 6.6 works fine. I was using vs build tools 2017 + mono 6.6 64b. Too bad i get api mismatch with the templates else i’d just reupload an alternative binary for others to use.

It also fixes the missing “build” button & drop down in the editor menu for build tool. So I’m guessing cross compilation error for windows. System.Native.dll doesn’t exist on windows
