See: http://stackoverflow.com/questions/14085274/c-decltype-fails-to-deduce-type Try to use decltype on the address of a function template specialization and it will fail. It should work.

The following code produces an error: class Foo; Foo& CreateFoo(); void foobar() { CreateFoo(); } --- The following change compiles fine: Foo& foo = CreateFoo(); --- The documentation for compiler error C2027 states "Visual C++ does not allow a reference to an undefined type." and provides an example very similar to this one. In reality, undefined types work fine in most cases, just not this particular case. --- It seems like the problem may be that undefined types cannot be convert...

See the code: #include #include struct Copy { Copy(){} Copy(const Copy&) { std::cout << "Copied!\n"; } Copy(Copy&&) { std::cout << "Moved!\n"; } }; int main() { Copy copy; std::function func = [=]() {(void)copy;}; return 0; } It does print "Copied!" 2 times and GCC with CLang print "Copied!\nMoved!"

I am currently trying new C++11 feature, and in particular its support by Visual Studio 2012 (both regular and November 12 CTP releases). I wanted to know how unscoped enumerations with a specified storage class behave with function overloads. The result surprised me, but I thought it was the behavior specified in C++11 standard. So I asked a question to StackOverflow if anyone could tell me the reason. From the answer of GManNickG, it happens that this is a Microsoft compiler bug. Visual Studi...

I'm actually using the VS11 beta rather than VS2012 RC C++ value-initialization is not working as specified in C++11. A type with an implicitly declared, non-trivial default constructor is not being zero-initialized before the constructor is called when value initialization is requested. VS11 appears to still be following C++98 rules

After upgrading from TFS 2013 Update 4 to TFS 2015 RC we get the following error in Visual Studio 2013: "String reference not set to an instance of a String. Parameter name: s" It happens all the time when doing any of the following in Team Explorer: * Click "Home", "Refresh", then "Builds" * Click "Home", "Refresh", then "Unsynced Commits". It also sometimes happens when clicking on "Fetch" after someone else has pushed some code to the Git Repo.

Some of our users are unable to set their User Profile picture in the TFS 2015 RC web interface. The users in question did not have profile pictures before the upgrade. After the upgrade they were able to set their picture, but it went missing (along with some other users') and now they're not able to set new pictures. Clicking on "My Profile", then "Change Picture" brings up the "Profile Image" dialog as expected. A new picture file can be chosen and displays correctly in the "Profile Ima...
