Seems like more people are concerning on the WinFX renaming to .NET 3.0. There is a petition in the web written by Rei Miyasaka.
WinFX was renamed to .NET 3.0. This decision was made without any community feedback, which is uncharacteristic of Microsoft's recent openness to community input.
Not only is .NET 3.0 a misnomer, it throws a wrench in the .NET Framework, likely jamming future versions. It is also a severe inconvenience to developers, especially newcomers.
We ask that this short-sighted decision be turned around before the first release of the framework for its own sake as well as the sake of developers…
If you are agree with this you can sign for "Reverse WinFX Petition".
