Visual Studio 2015：C ++ REST API（卡萨布兰卡）在VS包含/标题中编译失败 [英] Visual Studio 2015: C++ REST API (Casablanca) failing compilation in VS includes/headers

问题描述

我今天安装了 Visual Studio 2015 专业版，并创建了 C ++ Win32控制台应用程序

然后我想要使用C ++ REST SDK（卡萨布兰卡），因此我使用NuGet包管理器下载了v14，并使用

点击第一个错误，它将转到此处

无法理解为什么VS包含的编译失败。
因此，我创建了另一个项目，然后放入 hello world，它就可以正常工作

请帮助

解决方案

I已安装 Visual Studio Community Edition 2015 。之后，我从NuGet安装了Casablanca。和所有的工作。我似乎安装已损坏/是RC，例如

卡萨布兰卡版本-> cpprestsdk.v140。 windesktop.msvcstl.dyn.rt-dyn.2.8.0

I installed Visual Studio 2015 Professional edition today and created a C++ Win32 console application

Then I want to use C++ REST SDK (Casablanca), so I downloaded it v14 using NuGet package manager And created a sample program using this link

However, when I compiled, I am getting errors in VS includes..

Clicked on first error, it takes to here

Can't understand why VS includes are failing compilation. So, I created another project and just put "hello world" and it worked fine

Please help

解决方案

I installed Visual Studio Community Edition 2015. After that I installed Casablanca from NuGet. And all worked. I seems that the installation was corrupted / was a RC, as

Casablanca Version --> cpprestsdk.v140.windesktop.msvcstl.dyn.rt-dyn.2.8.0
