DevDiv vs WinDev. The Windows group maintains the C++ compiler. So you get the resource editor for dialog templates and that’s about it. And that actually got worse from Visual Studio .NET onwards, my guess is that it got took over by the DevDiv people when they unified the IDEs.
Windows could have been like Android, regarding the extent of managed languages usage and NDK, if DevDiv and WinDev had actually collaborated in Longhorn, but I digress.
