Covariant Return Types

[Nexer8]

Are there any plans to support covariant return types in Unity 2022.1?

I know they were dropped for Unity 2021.2, but it sounded like the feature almost made it. Something to do with runtime C# 9 support.

No, we don’t expect to get covariant return type support until we ship CoreCLR as a JIT runtime. The version of Mono we ship from the mono/mono repository does not have covariant return type support, and adding it would not be worthwhile. A faster path to get it is to focus on a CoreCLR player, which is what we are doing now.

We don’t have a release date set yet for the CoreCLR player, but I’ll update here as soon as we do.
