visual-studio-2012 - 在VS 2012中导入SvsServiceProvider

我是Visual Studio可扩展性的新手，我尝试从VS 2012 SDK(Displaying Statement Complete)实现Microsoft演练之一。我在演练中上一节课有些困难。问题是我收到 undefined SVsServiceProvider的错误。我已经导入了Microsoft.VisualStudio.Shell。

Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.ComponentModel.Composition
Imports System.Runtime.InteropServices
Imports Microsoft.VisualStudio
Imports Microsoft.VisualStudio.Editor
Imports Microsoft.VisualStudio.Language.Intellisense
Imports Microsoft.VisualStudio.OLE.Interop
Imports Microsoft.VisualStudio.Shell
Imports Microsoft.VisualStudio.Text
Imports Microsoft.VisualStudio.Text.Editor
Imports Microsoft.VisualStudio.TextManager.Interop
Imports Microsoft.VisualStudio.Utilities


<Export(GetType(IVsTextViewCreationListener))>
<Name("token completion handler")>
<ContentType("plaintext")> <TextViewRole(PredefinedTextViewRoles.Editable)>
Friend Class TestCompletionHandlerProvider
Implements IVsTextViewCreationListener

<Import()>
Friend AdapterService As IVsEditorAdaptersFactoryService = Nothing
<Import()>
Friend Property CompletionBroker() As ICompletionBroker
<Import()>
Friend Property ServiceProvider() As SVsServiceProvider

Public Sub VsTextViewCreated(ByVal textViewAdapter As IVsTextView) Implements IVsTextViewCreationListener.VsTextViewCreated
    Dim textView As ITextView = AdapterService.GetWpfTextView(textViewAdapter)
    If textView Is Nothing Then
        Return
    End If

    Dim createCommandHandler As Func(Of TestCompletionCommandHandler) = Function() New TestCompletionCommandHandler(textViewAdapter, textView, Me)
    textView.Properties.GetOrCreateSingletonProperty(createCommandHandler)
End Sub

最佳答案

正如Simon在对原始问题的评论中所发布的，添加对以下内容的引用:

Microsoft.VisualStudio.Shell.Immutable.10.0.dll

如果您使用的是Microsoft.VisualStudio.Shell.Immutable.11.0.dll，那么您将遇到一个空SvsServiceProvider。
