为什么从Visual Studio 2008中删除了在新的ATL项目中使用属性的选项? [英] Why the option to use attributes in new ATL projects was removed from Visual Studio 2008?

问题描述

这是MSDN注释中的文本:根据ATL Internals(第2版)一书，不建议使用属性，并且不应在新的ATL项目中使用."

This is the text from MSDN comment: "According to the book ATL Internals (2ed) the use of attributes is deprecated and should not be used in new ATL projects."

但是为什么?！

推荐答案

在ATL中，这些属性是编译器的把戏.它们不像C#中的属性那样是平台的核心部分.与宏相比，它们还更容易调试，并且转储生成的属性代码的方法很麻烦.

In ATL these attributes were a compiler trick. They were not a core part of the platform like attributes in C#. They were also more confusing to debug than macros's and the method of dumping generated attribute code was a hassle.

我怀疑另一个问题可能是C ++编译器的兼容性和标准遵循性.属性并不能构成更漂亮的C ++代码，也许将来的实际C ++标准版本中可能会使用此语法.

I suspect another issue is likely to have been C++ compiler compatibility and standards-adherence. Attributes didn't make for more beautiful C++ code, and perhaps this syntax may be used in a future version of a real C++ standard.
