            Bug ID: 45588
           Summary: .Net Framework 4.5.2 (WPF) requires
                    windowscodecs.dll.IWICPixelFormatInfo_GetChannelCount_
                    Proxy
           Product: Wine
           Version: 3.13
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: windowscodecs

"Content Manager" (https://acstuff.ru/app/
https://assettocorsa.club/index.php?q=content-manager.html) is an alternative
launcher for Assetto Corsa. That one requires/uses WPF from .Net Framework
4.5.2. The launcher works surprisingly well and much better that the original
Assetto Corsa launcher which I never got to work. Anyway, "Content Manager"
works fine in wine once .Net 4.5.2 is installed, though with several actions,
like selecting a track, the program crashes with:

wine: Call from 0x7b43d85b to unimplemented function
windowscodecs.dll.IWICPixelFormatInfo_GetChannelCount_Proxy, aborting

Looking at
https://github.com/wine-mirror/wine/blob/master/dlls/windowscodecs/windowscodecs.spec#L103
this method is indeed not implemented in the wine implementation of
windowscodecs. It would be nice if this method could be implemented. I don't
know if IWICPixelFormatInfo_GetBitsPerPixel_Proxy and
IWICPixelFormatInfo_GetChannelMask_Proxy are also needed, but could imagine
that this is the case.

PS: Installing the native version of windowscodecs is a somewhat of a
work-around. The application does no longer crash, but then a lot of images are
no longer displayed correctly (looks like transparent is displayed as white).

Kind regards.
