That's not true. C++ .NET was replaced by C++/CLI, which has a much nicer syntax.
Microsoft is certainly pushing .NET hard. However, Windows operating systems will be able to run "native" C++ code for a very long time yet. And actually, C++.NET has already been deprecated (MS are no longer supporting it). They recommend using C# or Visual Basic to develop .NET applications.
Edit: Seems like I should read the thread before posting :)
