如何告诉 VS 包我想订阅 IDTExtensibility2

Question

我正在尝试创建一个 VS2013 扩展，以便我可以收到构建事件的通知。

我创建了一个 VS 包，我有一个示例 Connect 类，它实现了 IDTExtensibility2，并在其中包含了 OnBuildProjConfigBegin 事件所需的代码。

我如何告诉包使用该类？

我的 Connect 课程如下供参考，但我认为我需要在其他地方进行一些更改才能使其正常工作：

Imports System
Imports Microsoft.VisualStudio.CommandBars
Imports Extensibility
Imports EnvDTE
Imports EnvDTE80
Imports System.IO
Imports System.Collections.Generic
Imports System.Windows.Forms

Public Class Connect

Answer 1

包不应该也不需要实现 IDTExtensibility2。有几个解决方案：

• 使用自动化模型 (EnvDTE)，按照HOWTO: Get an EnvDTE.DTE instance from a Visual Studio package 中的说明获取 DTE 实例，然后使用 DTE.Events.BuildEvents。

• 避开自动化模型，使用原生VS服务，如IVsBuildableProjectCfg.AdviseBuildStatusCallback方法和IVsBuildStatusCallback
