Will project “Roslyn” change how developers use Visual Studio?
The Roslyn Community Technology Preview (CTP) was released in October 2011. To help understand the significance and the promise of the Roslyn project, I've prepared a series of questions and answers. The questions are my own and the answers are based on my experience using the Roslyn CTP, along with my own research; but you can have confidence in the answers, as they've been reviewed for accuracy by Dustin Campbell and Kevin Pilch-Bisson of Microsoft's Roslyn team.
Roslyn is a CTP and there are many unfinished areas; it's not yet language complete. As a CTP, Roslyn includes features in C# that aren't yet available in Visual Basic, such as the C# interactive window, the C# scripting engine and the C# script code file format (.csx). That said, Roslyn is being developed under the principle of language co-evolution, so any feature seen in either C# or Visual Basic can be expected to be present in the other when Roslyn is released.
