A disappointment at Microsoft\u2019s Build conference last month was lack of news about the next version of C#, version 6.0. C# architect Anders Hejlsberg did present a session, but it was on TypeScript, a language which compiles to JavaScript.<\/p>\n

Aside: Hejlsberg talks about the new Xbox music app in Windows 8.1 (and Xbox One) which is written in JavaScript. It is a large app with 500,000  lines of code, and new features are now implemented in TypeScript (30,000 lines so far). <\/p>\n

However, Hejlsberg did also talk about C# 6.0 at Build, during this Channel 9 Q&A<\/a>, though you have to scroll through to reach the C# content (about 34 minutes in).<\/p>\n

He confirmed that C# in Visual Studio 2013 is the same as before, but there will be new previews of the forthcoming \u201cRoslyn\u201d compiler soon, and that C# 6.0 will be in the \u201cnext Visual Studio after\u201d which suggests Visual Studio 2014, presuming Microsoft sticks to its annual release cycle.<\/p>\n

\u201cWe are at a point where the Roslyn compilers are done,\u201d he said.<\/p>\n

Roslyn, Hejlsberg explained, is the new compiler for \u201cC#, and VB, and the language services in the IDE.\u201d<\/p>\n

Roslyn performance will be at least as good as the existing native compiler, says Hejlsberg. It is better suited to parallel processing so will take advantage of multi-core machines, \u201cparticularly for large projects.\u201d<\/p>\n

You can read more about Roslyn here<\/a>. Microsoft describes it as \u201copening up the Visual Basic and C# compilers as APIs.\u201d Practical benefits include features like instant porting of VB code to and from C#, and the use of C# and VB as macro languages within a .NET application.<\/p>\n

Hejlsberg also says that Roslyn will enable a faster pace of evolution for C# in future. <\/p>\n

Another aside: Xamarin<\/a>, which provides a compiler for C# targeting iOS and Android, gets a nod of approval from Hejlsjberg. \u201cI\u2019m a great fan of their work,\u201d he says.<\/p>\n
