这个问题参考了此处http://ssmsaddin2012.codeplex.com/SourceControl/changeset/view/19629#101185的 SSMSAddinDenali SQL Server Management Studio 2012 Addin 。在尝试构建 SSMS 2012 插件时，我无法使用 .Net 4.0/4.5 实现 IObjectExplorerService。我想知道是否有人可以公开有关连接到 ObjectExplorerService 的更多信息；如何在数据库表上下文菜单中创建菜单项。我收到此错误（无法将 Microsoft.SqlServer.Management.SqlStudio.Object.ObjectExplorerService 类型转换为 Microsoft.SqlServer.Management.SqlStudio.Object.ContextService 类型）
我需要更新以使其构建的重要参考资料：
Microsoft.SqlServer.Management.SDK.SqlStudio
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\Microsoft.SqlServer.Management.Sdk.SqlStudio.dll版本 11.0.0.0
Microsoft.SqlServer.Management.SqlStudio.Explorer
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\Extensions\Application\Microsoft.SqlServer.Management.SqlStudio.Explorer.dll版本 11.0.0.0
SqlPackageBase
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\SqlPackageBase.dll版本 11.0.0.0
SqlManagerUI
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\SQLManagerUI.dll版本 11.0.0.0
SqlWorkbench.Interfaces
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\SqlWorkbench.Interfaces.dll版本 11.0.0.0
在我构建我的插件并在 SSMS 2012 中运行它之后，我的 try catch 出现了这个错误，显示的代码
任何进一步的帮助将不胜感激！
