I didn't have .NET Framework 3.5 installed.
I made a commit adding that directory: https://github.com/madewokherd/wine-mono/commit/ d30b97b0af371fb655159e7a29705df5fe43502e
Nice
But I'm just seeing a crash in mshtml. If I'm reading this correctly, OleObject_SetClientSite attempts to call IDocHostUIHandler_GetHostInfo, but the method is NULL in the object's vtable, so it crashes.
I marked component for this bug to mshtml for that in this repott; Maybe open a seperate bugreport to track the (already solved by you) .Net issue?
