调试时不调用 Visual Studio 包初始化方法

Question

目前，我正在使用 MEF 开发 Visual Studio 2010 的扩展，我需要初始化我的全局状态。我正在尝试在 Package.Initialize 方法中做到这一点

[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();
    }
}

我还有一个使用此状态的 MEF 分类器提供程序

[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));
    }
}

包和 MEF 分类器都在同一个程序集中。当我开始调试并放置断点时，我看到该程序集已加载。但是 MyClassifierProvider 在 MyPackage.Initialize 调用之前已经被初始化。所以我无法在任何 MEF 组件启动之前初始化我的全局状态。谁能解释为什么以及如何避免这种行为？

谢谢

我找到了答案。需要添加ProvideAutoLoad属性

所以最终的类声明是

[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
