当解决方案已完全加载时,我想收到通知。受此answer的启发,我尝试实现IVsSolutionEvents
。
当我加载具有两个C#项目的解决方案时,请等到加载完成并最终关闭Visual Studio 2017时,输出仅显示以下跟踪消息:
VSTestPackage1: OnAfterOpenProject
VSTestPackage1: OnQueryCloseSolution
VSTestPackage1: OnQueryCloseProject
VSTestPackage1: OnQueryCloseProject
VSTestPackage1: OnBeforeCloseSolution
VSTestPackage1: OnQueryCloseProject
VSTestPackage1: OnBeforeCloseProject
VSTestPackage1: OnQueryCloseProject
VSTestPackage1: OnBeforeCloseProject
VSTestPackage1: OnAfterCloseSolution
这是预期的行为吗?为什么不调用OnAfterOpenSolution
?
这是包的实现:

if (_hSolutionEvents != uint.MaxValue)
{

参考方案
是的,这是设计使然。观察到此行为的原因是,相关事件在加载程序包之前触发。关闭解决方案,然后重新打开它(在装入程序包之后),可以观察事件确实触发来进行测试。在第二遍,您将看到事件触发。
您的示例使用的是SolutionHasMultipleProjects上下文guid,它确保仅当解决方案具有多个项目时才加载您的包。 IDE确定的唯一方法是先加载解决方案负载,然后设置UI上下文。因此,基本上,您设置事件处理程序的时间为时已晚。
如果要确保收到该特定通知,可以注册软件包以使用NoSolution_string和SolutionExists_string加载。但这有点邪恶,因为这会迫使您的程序包始终加载(即使不需要时也是如此),这是不太理想的解决方案。
使用SolutionExistsAndFullyLoadedContext可能是更好的方法。最初加载软件包时,您会知道已经满足条件,并且可以在从软件包的Initialize覆盖返回之前运行处理程序代码。您的原始IVsSolutionEvents处理程序将在后续解决方案加载时调用。
您可能还需要考虑注册/使用基于规则的UI上下文,如下所述:
