Microsoft has announced a new Visual C++ Compiler CTP (Community Technology Preview):

Announcing the Visual C++ Compiler November 2013 CTP

In addition to the ISO C++ features added in last month's Visual c++ 2013 full release, this CTP adds the following additional ISO C++11 and draft ISO C++14 features in preview form:

• Implicit move special member function generation (thus also completing =default)
• Reference qualifiers on member functions (a.k.a. "& and && for *this")
• Thread-safe function local static initialization (a.k.a. "magic statics")
• Inheriting constructors
• alignof/alignas
• __func__
• Extended sizeof
• constexpr (except for member functions)
• noexcept (unconditional)
• C++14 decltype(auto)
• C++14 auto function return type deduction
• C++14 generic lambdas (with explicit lambda capture list)
• (Proposed for C++17) Resumable functions and await

The new CTP installs as a new toolset under the Visual C++ 2013 IDE, allowing editing and building using the new Visual C++ compiler through the current shipping IDE. As this is a CTP, however, there is not yet other IDE support, and so for example the IDE may display red squiggles on valid code that will actually compile and run, as shown in the accompanying screenshot which exercises a generic lambda function having an auto parameter. If you do not already have a copy of Visual C++ 2013 installed and would like a free copy, several versions of the Visual C++ 2013 Express optimizing compiler are available for free via the Visual Studio Downloads page.
