Visual Studio包调试时不调用Visual Studio包Initialize方法

Question

目前，我正在使用MEF开发Visual Studio 2010的扩展，并且需要初始化我的全局状态。我试图做到这一点在Package.Initialize方法

[PackageRegistration(UseManagedResourcesOnly = true)] 
[InstalledProductRegistration("#110", "#112", "1.0.0.0", IconResourceID = 400)] 
[Guid("1AF4B41B-F2DF-4F49-965A-816A103ADFEF")] 
public sealed class MyPackage : Package 
{ 

    protected override void Initialize() 
    { 
     ContainerConfigurator.Configure(); 
     ContainerConfigurator.IsInitialized = true; 
     base.Initialize(); 
    } 
} 

而且我有一个使用这种状态

[Export(typeof(IClassifierProvider))] 
[Name("This is my provider")] 
[ContentType("DebugOutput")] 
[ContentType("Output")] 
public class MyClassifierProvider : IClassifierProvider 
{ 
    [Import] 
    private IClassificationTypeRegistryService _classificationRegistry = null; // MEF 

    public IClassifier GetClassifier(ITextBuffer textBuffer) 
    { 
     // This always false 
     if (!ContainerConfigurator.IsInitialized) 
      throw new InvalidOperationException(); 

     return textBuffer.Properties.GetOrCreateSingletonProperty(() => new TypedClassifier(ServiceLocator.Current, _classificationRegistry)); 
    } 
} 

的两个包和MEF分类是在同一组件上的MEF分类供应商。当我开始调试并放置一个断点时，我看到这个组装被加载。但MyClassifierProvider已在MyPackage.Initialize调用之前初始化。所以我无法在启动任何MEF组件之前初始化我的全局状态。任何人都可以解释为什么以及如何避免这种行为？

谢谢

我找到了答案。这是需要添加ProvideAutoLoad属性

所以最终的类声明

[PackageRegistration(UseManagedResourcesOnly = true)] 
[InstalledProductRegistration("#110", "#112", "1.0.0.0", IconResourceID = 400)] 
[Guid("1AF4B41B-F2DF-4F49-965A-816A103ADFEF")] 
[ProvideAutoLoad("ADFC4E64-0397-11D1-9F4E-00A0C911004F")] 
public sealed class MyPackage : Package
