[dreddy-work]

@Olina-Zhang , is this the case with main as well?

[dreddy-work]

@safern, do you know anything changed in RC for Drawing.Common?

[ericstj]

We did change 2ccf787 however that should only apply on Unix. @ViktorHofer perhaps something changed in how we share this binary with WinForms to give them the wrong implementation?

[ericstj]

I can confirm this. Rather than picking up the Windows implementations WindowsDesktop is getting the RID-less implementations. @ViktorHofer I think it's due to this:

runtime/src/libraries/Microsoft.Internal.Runtime.WindowsDesktop.Transport/src/Microsoft.Internal.Runtime.WindowsDesktop.Transport.proj

Line 3 in 948770a

@ViktorHofer I have labeled this issue as infrastructure and 6.0 milestone. Feel free to label it back to System.Drawing if this is not the case.
