Task: Question Answering
Input (English): passage: Microsoft is leading the development of the open-source reference C# compiler and set of tools, previously codenamed ``Roslyn''. The compiler, which is entirely written in managed code (C#), has been opened up and functionality surfaced as APIs. It is thus enabling developers to create refactoring and diagnostics tools. While other implementations of C# exist, Visual C# is by far the one most commonly used. The Unity game engine uses C# as its primary scripting language.
 question: is c# and visual c# the same?
Output (English): No
