我试图通过执行自定义Sql使用Entity Framework Migration创建FULL TEXT索引.

我的迁移类看起来像这样:

public partial class DocumentContentFullTextIndex : DbMigration
{
    public override void Up()
    {
        AlterColumn("dbo.Attachments", "ContentType", c => c.String(maxLength: 260));

        Sql("CREATE FULLTEXT CATALOG FullTextIndexes AS DEFAULT;", true);

        Sql(@"CREATE FULLTEXT INDEX ON [Attachments](
Content
    TYPE COLUMN ContentType
    Language 'ENGLISH'
)
KEY INDEX [PK_dbo.Attachments]
ON FullTextIndexes;", true);
    }

    public override void Down()
    {
        AlterColumn("dbo.Attachments", "ContentType", c => c.String(maxLength: null));

        Sql("DROP FULLTEXT INDEX ON [Attachments]");
        Sql("DROP FULLTEXT CATALOG FullTextIndexes");
    }
}

当我从MSSQL管理工作室运行它时,一切都很完美,SQL完全符合我的预期.

但是当从迁移项目运行时,第二个Sql请求会触发异常

超时已过期.操作完成之前经过的超时时间或服务器没有响应.
