The timing of this is amazing. I was literally just looking for a solution for the RuntimeType issue lol.

Can we got a build of this soon? I'm working on net20 support for my mod loader, and otherwise I'd have to fall back to the older versions of MonoMod

Can always use the CI builds. That said, net20? I don't think there's anything these days that requires net20. (Even truly ancient Unity games target net35.)

[slxdy]

Nope. There a lots of old mono games that use net20.
Also, the first commit in this PR is a fix specifically for net20

Do those builds also get uploaded to nuget?

It's not, though. That's a fix that's present on old Mono, which is net35.

Not at the moment. I want to have them upload to GitHub Packages, but haven't set that up just yet.

Either way, I will just wait for the new nuget then. But thanks for merging this
