- Editor: When a compile error is emitted for an assembly, clear all compile errors for all assemblies that reference it directly or directly. This improves workflows when dealing with compile errors, as fixing an assembly's compile errors might also fix compile errors in any assemblies that reference the assembly directly or indirectly.
