The current version of Visual Studio (2013) came with a minor framework update in form of the .NET-Framework 4.5.1. What was missing? An update of the C# language! Not even Roslyn was included, but I think that this is no problem at the moment, since it is quite likely to be included in the next version. Aren't we happy with the range of possibilities that are delivered by C#? I think that has nothing to do with the fact that software is never finished and that one can always improve something.
