VS 2017 数据库项目因超时错误导入数据库失败

Question

VS 2017 数据库项目无法导入数据库：在尝试对 Microsoft.Data.Tools.Schema.Sql.SchemaModel.SqlSpatialIndex 类型的元素进行逆向工程时从 SQL 服务器收到错误：超时已过期。操作完成前超时期限已过或服务器未响应。

我在 SSDT 17，版本 15.6.5 中创建了一个 SQL 服务器数据库项目。我能够导入一些小型数据库。但是未能导入我们相当大的主数据库。

在收集列存储索引时导入失败，出现以下错误：

我还检查了 SQL 服务器 activity 监视器，它正在运行下面的查询，但是当我尝试手动运行它时它没有返回任何内容：

我也尝试更改为连接超时设置，但没有成功。

我也有这个问题，甚至使用 QueryCommandTimeout 的注册表设置和其他类似错误的解决方案。可能不是 "solution" 但这是我能够解决此问题的方法。我从命令行运行 SqlPackage 工具，然后导入生成的 DACPAC:

"C:\Program Files (x86)\Microsoft SQL Server0\DAC\bin\SqlPackage.exe" /Action:Extract /SourceConnectionString:"Data Source=localhost;Initial Catalog=MyDB;Integrated Security=True;" /TargetFile:"path\to\database.dacpac" /p:CommandTimeout="0"

注意 /p:CommandTimeout="0"。在转到 0 之前，您可能想为此尝试较大的值。
