订阅EnvDTE80.DTE2.Events2.PublishEvents.OnPublishBegin的正确方法是什么？

我正在将VS插件移植到VS包中。 初始化包时，包会订阅OnBuildBegin和OnPublishBegin。 Visual Studio按预期触发OnBuildBegin，但从不调用OnPublishBegin。

或多或少相同的代码在Visual Studio 2013,2012和2010中作为插件工作。 但是在VS 2015中作为VS包，OnPublishBegin似乎不起作用。

示例代码如下。

测试运行调试器的代码，该调试器配置为在实验模式下启动VS的第二个实例。 在第二个实例中，我打开另一个解决方案并使用“发布向导”发布。

using System.Diagnostics.CodeAnalysis; using System.Runtime.InteropServices; using System.Windows.Forms; using EnvDTE; using EnvDTE80; using Microsoft.VisualStudio.Shell; using Microsoft.VisualStudio.Shell.Interop; namespace MyPackage { [PackageRegistration(UseManagedResourcesOnly = true)] [InstalledProductRegistration("#110", "#112", "1.0", IconResourceID = 400)] // Info on this package for Help/About [Guid(VSPackage.PackageGuidString)] [SuppressMessage("StyleCop.CSharp.DocumentationRules", "SA1650:ElementDocumentationMustBeSpelledCorrectly", Justification = "pkgdef, VS and vsixmanifest are valid VS terms")] [ProvideAutoLoad(UIContextGuids80.SolutionBuilding)] public sealed class VSPackage : Package { public const string PackageGuidString = "a8ddf848-00ea-4e4e-b11a-65663a8a8021"; private DTE2 application; public VSPackage() { } protected override void Initialize() { base.Initialize(); this.application = (DTE2) this.GetService(typeof(DTE)); ((Events2)this.application.Events).BuildEvents.OnBuildBegin += this.OnBuildBegin; ((Events2)this.application.Events).PublishEvents.OnPublishBegin += this.OnPublishBegin; } private void OnBuildBegin(vsBuildScope scope, vsBuildAction action) { MessageBox.Show("OnBuildBegin"); } private void OnPublishBegin(ref bool pubContinue) { MessageBox.Show("OnPublishBegin"); } } } 

任何人都可以为我解决这个问题吗？

强烈建议保留对Events对象的引用以保护它们免受GC的影响：

 protected override void Initialize() { events = application.Events; buildEvents = events.BuildEvents; publishEvents = events.PublishEvents; buildEvents.OnBuildBegin += this.OnBuildBegin; publishEvents.OnPublishBegin += this.OnPublishBegin; } private Events2 events; private BuildEvents buildEvents; private PublishEvents publishEvents;
