Not sure if this is linked to the interop issue and fix in , but I’m now getting an error when trying to “Add Reference”


This happens even when trying to add reference in a clean / new Winforms Oxygene project - as per the above screenshot. It doesn’t happen in a standard Microsoft C# project.

As per the error, it does seem related to mscorlib which gets included as standard in Oxygene projects but C# ones see to not allow it as it is referenced in the build system directly ?

My mscorlib is :-

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2\mscorlib.dll

Ist mir letzte Woche auch passiert. Mit .NETFramework 4.8.

Thanks, logged as bugs://83597

To be clear, this happens adding any reference, or imply specific ones? What version of VS?


Any reference Marc :-

1). Right click on references
2). Click Add Reference
3). Error as per screenshot.

… and I’m using VS 2017 community

Same thing also on VS 2019, since .2458

FTR, be careful with 2458 firehose builds from Thursday or later, there’s some major compiler subtle breakage.

Ok, thank you for the information!
I’ll be careful and keep the eyes open. Thanx.
