visual-studio-2015 - DACPAC无法部署，因为 'can'无法连接到服务器吗？

我正在尝试将DACPAC部署到LocalDB 2012，但事实并非如此:

堆栈跟踪如下:

==================================

Could not deploy package. (Microsoft.SqlServer.Dac)

Program Location:

===================================

Unable to connect to target server. (Microsoft.Data.Tools.Schema.Sql)

   at Microsoft.SqlServer.Dac.OperationExtension.CompositeOperation.Microsoft.SqlServer.Dac.IOperation.Run(OperationContext context)
   at Microsoft.SqlServer.Dac.DeployOperation.Microsoft.SqlServer.Dac.IOperation.Run(OperationContext context)

现在，由于我正尝试通过SSMS进行部署，因此我知道可以连接到服务器了。我已经在Visual Studio中检查了解决方案，并且目标版本适用于SQL Server 2012，并且连接字符串似乎正确。

有趣的是，通过Visual Studio进行部署是可行的，但是后来我无法将数据库升级到数据层应用程序，我收到以下消息:

===================================

   at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

我想念什么？

最佳答案

更新到最新版本的SSMS应该可以解决此问题。在这里可用:https://msdn.microsoft.com/en-us/library/mt238290.aspx

否则，请确认您使用的LocalDB版本是LocalDB2012。为此，您可以对服务器运行以下查询:

select @@version

11.0.xxxx = SQL Server 2012的

12.0.xxxx = SQL Server 2014的

13.0.xxxx = SQL Server 2016的

处理dacpac部署的库称为数据层应用程序框架或DacFX。 SSMS 2012使用的DacFX版本安装在:

C:\program files (x86)\Microsoft Sql Server\110\DAC\bin

请注意路径中的“110”，表示DacFX的版本最多支持SQL Server2012。SSMS2014在相似的路径中查找DacFX，但是在120文件夹中，并且DacFX的版本最多支持SQL Server 2014，等等。

当要求DacFX部署到比支持的版本新的服务器版本时，它将给出“无法连接”错误消息。 (顺便说一下，错误消息已在较新版本的DacFX中得到改进)。

在某个时间点，Visual Studio使用了上述路径中安装的DacFX版本，但是在SQL Server工具中发布SQL Server 2014支持的同时，进行了更改，并且Visual Studio在以下位置获得了自己的DacFX副本。

C:\program files (x86)\Microsoft Visual Studio XX.0\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\120

因此，这就是您如何在不同版本的Visual Studio和SSMS之间获得不同的行为。
