Microsoft is letting devs download the preview version of Visual Studio 14, due for 2015 release, for feedback.
The CTP – community technology preview – download is available here.
It will work with Roslyn – more formally, the .NET Compiler Platform – that Redmond open sourced at its April Build conference. Roslyn exposes the MS Visual Basic and C# compilers as APIs.
The compiler-as-a-service, MS says in this MSDN blog post, is behind a bunch of features that include build

• IntelliSense
• refactoring
• CodeLens
•   debugging.

“C# refactoring support has been completely revamped including two new core refactorings: Inline Temporary Variable and Introduce Explaining Variable. Additionally, refactoring support for Visual Basic has been added for the first time”, S Soma" Somasegar continues in the post.
The release also gives devs a chance to check out ASP.NET vNext, which includes a cloud optimized mode that gets rid of libraries that aren't needed for server deployments.
“As well as the ASP.NET 4.5 Web Application templates, new templates are included for targeting ASP.NET vNext,” Somasegar notes.
The Visual C++ compiler is getting closer to standards-compliant, Somasegar says, listing its new features as
support for user-defined literals

•  noexcept 
•  alignof 
•  alignas
• inheriting constructors from C++11, 
•  generalized lambda capture
•  auto function return type deduction
•   generic lambdas from C++14.
