Question

我无法在Visual Studio中显示灯泡。试图仅运行here中的示例。但这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);
        }
    }

这是类TestSuggestedActionsSource

    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LowerCaseSuggestedAction类

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;
        }
    }

UpperCaseSuggestedAction类以类似的方式实现。就像我在示例中所做的一样，但是灯泡根本没有出现。这是我项目中的链接

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

我设法找到了解决此问题的方法。我马上说一些动作可能是多余的。在这里，我只告诉您我为使项目正常进行了哪些操作

1. 我在解决方案资源管理器中选择了我的项目
1. 通过“ VISX”部分中的“属性”窗口（视图>“属性”窗口），设置以下值：
  - a。在VISX Container中包含程序集= true
  - b。在本地部署中包含调试符号= true
  - c。在VISX容器中包含调试符号= true
1. 为项目Microsoft.VisualStudio.Language.Intellisense添加了一个库
1. 对于“属性”窗口中的Microsoft.VisualStudio.Language.Intellisense库，设置“复制本地= false”

然后下载了以下Nuget软件包：

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

其他版本的库都可以使用，但是如果放了它们，则应查看依赖关系。它们在那里密切相关

接下来，我在source.extension.vsixmanifest文件中添加了以下几行

<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：我希望这对某人有帮助。

Answer 2

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

我找到了文章VSSDK-Extensibility-Samples/LightBulb的存储库，并且可以正常工作。

VS 2017无法在我自己的扩展程序中显示“建议灯”
