4 or 5 years back I reported the bug that MS does not support multi-sized .ico files in .NET. The answer of one MS employee was that this was a bug, but not a critical one, so it would not be processed at the current point of time.
There is no fix / appropriate dealing with it to the current date.
Does anybody (successfully) deal with multi-size .ico files in .NET, or has everbody switched to the appropriate PNG files?
