It happens on 4.6.x as well, and it seems to be caused by actual
DllImports of 'System.Data.dll':
$ monodis System.Data.dll | grep pinvoke | grep System
.method assembly static hidebysig pinvokeimpl ("System.Data.dll" as
"DllBidTraceCW" unicode cdecl )
.method assembly static hidebysig pinvokeimpl ("System.Data.dll" as
"DllBidTraceCW" unicode cdecl )
...
These look to me like some MS Reference Source artifacts. Maybe
there is a native System.Data.dll under MS.NET which is providing
these exports :) No idea what it is.
