调试时不调用Visual Studio Package Initialize方法
本文关键字:Package Initialize 方法 Studio Visual 调用 调试 | 更新日期: 2023-09-27 18:07:16
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。我试着在包装里做。初始化方法
[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();
}
}
我也有一个MEF分类器提供程序使用这个状态
[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));
}
}
package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已经在MyPackage之前被初始化了。初始化的电话。因此,在启动任何MEF组件之前,我无法初始化我的全局状态。谁能解释一下为什么以及如何避免这种行为?
谢谢
我找到答案了。必须添加provideautolload属性

[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
