SSMS 2014 Addin ServiceCache Error

Question

我正在尝试使用sql server 2014 (visual studio 2013)获得当前连接，但我不断获得ServiceCache类型'Microsoft.SqlServer.Management.UI.VSIntegration。当我在ServiceCache调用上设置断点时，ServiceCache'存在于'SqlPackageBase.dll'和'Microsoft.SqlServer.SqlTools.VSIntegration.dll'中。有人知道如何解决这个问题吗?任何帮助都非常感激!

删除对Microsoft.SqlServer.SqlTools.VSIntegration.dll的引用。然后显式地添加对SQLPackageBase.dll

的引用
