C++11 features in Visual Studio 2012

问题

A preview version of Visual Studio 2012 (the next version after VS2010) is now available.

Does anyone know what new C++11 features it supports? (I\'m not in a position to try it out at the moment).

回答1:

It's worth noting that Visual Studio 2010 already had quite a bit of early C++11 support. So to summarize what is already linked to in other answers, here is what is new in Visual Studio 11 that was not part of Visual Studio 2010:

rvalue references to version 2.1 from 2.0
lambdas to version 1.1 from 1.0.
decltype to version 1.1 from 1.0^{(not yet available in developer preview)}
Improved, but still incomplete, Alignment
completed strongly-typed enums
forward declared enums
Standard layout and trivial types
Atomics
Strong compare and exchange
Bi-directional fences
Data-dependency ordering
Range-based for loop

In early November 2012, Microsoft announced the Visual C++ Compiler November 2012 CTP, which adds more C++11 functionality to Visual Studio 2012:

uniform initialization
initializer lists
variadic templates
function template default arguments
delegating constructors
explicit conversion operators
raw strings

Here is the list of feature of the new visual studio version and here is the list of what all compilers support

回答3:

There is a list there. What strikes me the most is the features which are still missing:

They said they would implement variadic templates as a priority and they didn't.
We will still have to declare move constructors by hand for many classes, since there is no delegating constructors.
Inheriting constructors aren't present, and this would really be needed for some code
No uniform initialization, in particular no initializer lists. This sucks when you have used them with g++.
Still no correct thread local storage. So you're stuck with boost::thread_specific_ptr for a while.

All the other features which are yet missing are mainly stuff you can live without. What I list here is just what nags me everyday when working with VS10. It's just so irritating that they didn't work on the compiler at all.

EDIT: I shall also add that emplace_back (one great feature for the standard library containers) isn't correctly implemented.

During GoingNative in Feb 2012, STL announced that range-for will be in VS11 starting with the beta, which is expected Feb 29th. A recording of the talk is available. "The Reveal" is at the one-hour 38 minute mark.
