Although not every new C# feature is as... pragmatic... as I would perhaps like, the language is continuing to evolve quite nicely. And the .NET framework doubly so.
One thing I would really like to see, is JSON literals on par with the XML literals that are available in VB.NET. Combined with LINQ, that makes for a quite interesting experience.
(Although the extent of the breakage in various tools, not just third-party solutions like Re# and Rider, but also VS.NET itself, possibly goes to the wrong side of 'interesting'...)
