VS 2017无法在我自己的扩展程序中显示“建议灯”

Question

我无法在Visual Studio中显示灯泡。试图从here运行一个例子。但它出于某种原因对我不起作用。

这是我的代码

    [Export(typeof(ISuggestedActionsSourceProvider))]
    [Name("Test Suggested Actions")]
    [ContentType("text")]
    internal class TestSuggestedActionsSourceProvider : ISuggestedActionsSourceProvider
    {
        [Import]
        internal ITextStructureNavigatorSelectorService NavigatorService { get; set; }

        public ISuggestedActionsSource CreateSuggestedActionsSource(ITextView textView, ITextBuffer textBuffer)
        {
            if (textBuffer == null && textView == null)
            {
                return null;
            }
            return new TestSuggestedActionsSource(this, textView, textBuffer);
        }
    }

这是TestSuggestedActionsSource类

    internal class TestSuggestedActionsSource : ISuggestedActionsSource
    {
        public event EventHandler<EventArgs> SuggestedActionsChanged;

        private readonly TestSuggestedActionsSourceProvider m_factory;
        private readonly ITextBuffer m_textBuffer;
        private readonly ITextView m_textView;

        public TestSuggestedActionsSource(TestSuggestedActionsSourceProvider testSuggestedActionsSourceProvider, 
            ITextView textView, ITextBuffer textBuffer)
        {
            m_factory = testSuggestedActionsSourceProvider;
            m_textBuffer = textBuffer;
            m_textView = textView;
        }

        private bool TryGetWordUnderCaret(out TextExtent wordExtent)
        {
            ITextCaret caret = m_textView.Caret;
            SnapshotPoint point;

            if (caret.Position.BufferPosition > 0)
            {
                point = caret.Position.BufferPosition - 1;
            }
            else
            {
                wordExtent = default(TextExtent);
                return false;
            }

            ITextStructureNavigator navigator = m_factory.NavigatorService.GetTextStructureNavigator(m_textBuffer);

            wordExtent = navigator.GetExtentOfWord(point);
            return true;
        }

        public Task<bool> HasSuggestedActionsAsync(ISuggestedActionCategorySet requestedActionCategories, SnapshotSpan range, CancellationToken cancellationToken)
        {
            return Task.Factory.StartNew(() =>
            {
                TextExtent extent;
                if (TryGetWordUnderCaret(out extent))
                {  
                    return extent.IsSignificant;
                }
                return false;
            });
        }

        public IEnumerable<SuggestedActionSet> GetSuggestedActions(ISuggestedActionCategorySet requestedActionCategories, SnapshotSpan range, CancellationToken cancellationToken)
        {
            TextExtent extent;
            if (TryGetWordUnderCaret(out extent) && extent.IsSignificant)
            {
                ITrackingSpan trackingSpan = range.Snapshot.CreateTrackingSpan(extent.Span, SpanTrackingMode.EdgeInclusive);
                var upperAction = new UpperCaseSuggestedAction(trackingSpan);
                var lowerAction = new LowerCaseSuggestedAction(trackingSpan);
                SuggestedActionSet suggestedActionSet = new SuggestedActionSet(
                    PredefinedSuggestedActionCategoryNames.Any, 
                    new ISuggestedAction[] { upperAction, lowerAction });
                return new SuggestedActionSet[] { suggestedActionSet };
            }
            return Enumerable.Empty<SuggestedActionSet>();
        }

        public void Dispose()
        {
        }

        public bool TryGetTelemetryId(out Guid telemetryId)
        {
            LightBulb telemetry  
            telemetryId = Guid.Empty;
            return false;
        }
    }

这是类LowerCaseSuggestedAction

internal class LowerCaseSuggestedAction : ISuggestedAction
    {
        private readonly ITrackingSpan m_span;
        private readonly string m_lower;
        private readonly string m_display;
        private readonly ITextSnapshot m_snapshot;

        public bool HasActionSets => false;
        public string DisplayText => m_display;
        public ImageMoniker IconMoniker => default(ImageMoniker);
        public string IconAutomationText => null;
        public string InputGestureText => null;
        public bool HasPreview => true;

        public LowerCaseSuggestedAction(ITrackingSpan span)
        {
            m_span = span;
            m_snapshot = span.TextBuffer.CurrentSnapshot;
            m_lower = span.GetText(m_snapshot).ToLower();
            m_display = $"Convert '{span.GetText(m_snapshot)}' to lower case";
        }

        public Task<object> GetPreviewAsync(CancellationToken cancellationToken)
        {
            var textBlock = new TextBlock();
            textBlock.Padding = new Thickness(5);
            textBlock.Inlines.Add(new Run() { Text = m_lower });
            return Task.FromResult<object>(textBlock);
        }

        public Task<IEnumerable<SuggestedActionSet>> GetActionSetsAsync(CancellationToken cancellationToken)
        {
            return Task.FromResult<IEnumerable<SuggestedActionSet>>(null);
        }

        public void Invoke(CancellationToken cancellationToken)
        {
            m_span.TextBuffer.Replace(m_span.GetSpan(m_snapshot), m_lower);
        }

        public void Dispose()
        {
        }

        public bool TryGetTelemetryId(out Guid telemetryId)
        {
            // This is a sample action and doesn't participate in LightBulb telemetry  
            telemetryId = Guid.Empty;
            return false;
        }
    }

类UpperCaseSuggestedAction以类似的方式实现。就像我在示例中所做的一切一样，但灯泡根本没有出现。以下是我在项目中的链接

在参考Microsoft.VisualStudio.Language.Intellisense中，参数Copy Local设置为false

我设法找到了解决这个问题的方法。我会立刻说某些行动可能是多余的。在这里，我将告诉你我为使项目工作所采取的行动

---

• 我在Solution Explorer中选择了我的项目
• 通过VISX部分中的“属性”窗口（视图>属性Windows），我设置了以下值： 一个。在VISX Container中包含程序集= true 湾在Local Deployment中包含调试符号= true C。在VISX Container中包含调试符号= true
• 向项目Microsoft.VisualStudio.Language.Intellisense添加了一个库
• 对于“属性”窗口中的Microsoft.VisualStudio.Language.Intellisense库，请设置“复制本地=假”

然后下载了以下Nuget包：

• Newtonsoft.Json v6.0.6
• System.ValueTuple v4.3.0
• Microsoft.VisualStudio.Validation v15.3.58
• Microsoft.VisualStudio.Threading.Analyzers v15.8.145
• Microsoft.VisualStudio.Threading v15.8.145
• StreamJsonRpc v1.3.23
• Microsoft.VisualStudio.Utilities v15.7.27703
• Microsoft.VisualStudio.OLE.Interop v7.10.6071
• Microsoft.VisualStudio.TextManager.Interop v7.10.6071
• Microsoft.VisualStudio.Shell.Interop v7.10.6072
• Microsoft.VisualStudio.TextManager.Interop.8.0 v8.0.50728
• Microsoft.VisualStudio.CoreUtility v15.8.525
• Microsoft.VisualStudio.Text.Data v15.6.27740
• Microsoft.VisualStudio.Shell.Interop.8.0 v8.0.50728
• Microsoft.VisualStudio.Shell.Interop.10.0 v10.0.30320
• Microsoft.VisualStudio.Shell.Interop.11.0 v11.0.61031
• Microsoft.VisualStudio.SDK.EmbedInteropTypes v15.0.21
• Microsoft.VisualStudio.Shell.Interop.15.6.DesignTime v15.6.27413
• Microsoft.VisualStudio.Shell.Interop.15.3.DesignTime v15.0.26929
• Microsoft.VisualStudio.Shell.Interop.12.0 v12.0.30111
• Microsoft.VisualStudio.Imaging.Interop.14.0.DesignTime v14.3.26930
• Microsoft.VisualStudio.Shell.Interop.14.0.DesignTime v14.3.26929
• Microsoft.VisualStudio.ImageCatalog v15.7.27703
• Microsoft.VisualStudio.Imaging v15.7.27703

其他版本的库可以工作，但是如果你把它们放在一起，你应该看一下依赖项。他们在那里密切相关

接下来，我将以下行添加到source.extension.vsixmanifest文件中

<Dependencies>
    <Dependency Id="Microsoft.Framework.NDP" DisplayName="Microsoft .NET Framework" d:Source="Manual" Version="[4.5,)" />
    <Dependency Id="Microsoft.VisualStudio.MPF.15.0" DisplayName="Visual Studio MPF 15.0" d:Source="Installed" Version="[15.0]" />
  </Dependencies>
  <Prerequisites>
    <Prerequisite Id="Microsoft.VisualStudio.Component.CoreEditor" Version="[15.0,16.0)" DisplayName="Visual Studio core editor" />
  </Prerequisites>
  <Assets>
    <Asset Type="Microsoft.VisualStudio.VsPackage" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%;PkgdefProjectOutputGroup|" />
    <Asset Type="Microsoft.VisualStudio.MefComponent" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%|" />
  </Assets>

PS：我希望这有助于某人。

我尝试了ЖуэльИтуа的解决方案，但无法在Visual Studio中显示灯泡（Visual Studio Community 2017，版本15.9.7）。该死的nuget包地狱。

我找到了文章的存储库，VSSDK-Extensibility-Samples/LightBulb，它工作正常。
