https://bugs.winehq.org/show_bug.cgi?id=49116 --- Comment #2 from Zebediah Figura <z.figura12(a)gmail.com> --- A bit of research later, I understand this better. BootstrapperApplicationFactory is irrelevant, because what CreateInstance() returns is System.ObjectHandle. The 0x38 offset is Unwrap(). The missing methods are those of System.Object itself. The CCW comes from System.Runtime.InteropServices.Marshal:GetCCW, which is an icall to mono/metadata/cominterop.c. That code seems to want to do the right thing, but it doesn't for some reason. It'll take some more debugging to figure out why. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
