DbMigration.SqlFile 生成 SqlException (0x80131904)：另一个会话正在使用事务上下文

Question

我已经创建了数据库迁移，在 Up 方法中我想用 SqlFile 方法执行 sql 文件。每个文件都包含 2 个语句：第一个是删除过程（如果存在），第二个是创建过程。两个语句都以 GO 结束。这是我在尝试应用迁移时遇到的异常：

存储过程包含对链接服务器的请求，这可能是问题的原因吗？

编辑

Up方法很简单：

    public override void Up()
    {
        SqlFile(@"Sql\sp_MergeData.sql");
    }

我调查过这与 SP 中的代码有关。我试图让它尽可能简单，之后我没有得到任何错误。带有合并语句和链接服务器选择的 SP。

我发现这个问题的原因是从链接服务器创建同义词 table 所以在执行 SP 代码之前数据库中没有。有解决方法吗？

我团队成员的机器上不存在问题，所以我暂时保持原样。

通过将 true 传递给非强制参数 suppressTransaction
