我的组织必须遵守极其严格且严格的规则才能获得认证和认证。在过去十年左右的时间里，我们已经开发了近百个VS宏，它们可以格式化代码，生成注释块，强制执行样式规则等。
我们的宏不是你记录鼠标移动的那种;它们都依赖于EnvDTE * VS自动化对象。随着VS 2012丢弃宏，我们不知道我们是否能够升级，而不会对团队造成严重影响。
我知道微软的方向是VS Addins路由，我愿意调查这条路线，但是我无法找到关于VS加载项如何与活动代码文件交互的代码示例或文档视觉工作室。
例如，这是一个我们一直使用的宏，它将Try包装器设计模式应用于所有能够抛出未处理异常的方法

有人可以指导我了解VS 2012加载项如何操作活动/开放代码文件（使用EnvDTE *或2012年可用的任何对象模型）？
答案 0 :(得分：4)
结果证明这很简单。原来宏对象模型是VS模型的一部分，所以没问题。

我应该知道微软不会让那些宏观依赖的开发人员像这样冷落！
