Unable to resolve reference 'UnityEngine.UI'. Is the assembly missing or incompatible with the current platform?

I have same issue after upgrade.

A work around would be use source code instead of dll.

1. delete odin’s assemblies directory.
2. decompress source.zip.
3. create unity’s assembly file inside each source directory.
4. fix assemblies.

Here’s fixed assemblies of sources.

Fixed in 2.1 when it releases

Doesn’t appear to be fixed in current 2.1 download. But disabling “Validate References” in the relevant DLLs and adding Unity.ugui to the compat layer (needed?) seems to fix it.

[Tor Esa Vestergaard]

Yeah. Fixed in 2.1, uh… when it releases - we might drop another beta build before then, but I don’t think the release is very far away.

I can provide a fixed build for now if you contact me on Discord.
