我正在寻找一个大型业务应用程序中的一个错误，该错误中的业务流程失败了，但是部分持久化到了数据库中。为了使问题更难弄清，该过程每隔几周就会失败一次，每次失败之间都会成功处理数十万次。当并发性/工作进程数增加时，错误频率似乎会增加。

到目前为止，我们已经能够重新创建该程序所看到的内容。（.NET 4.7.1框架）

        var transaction = sqlConnection.BeginTransaction();
        new SqlCommand($"INSERT INTO TestTable VALUES('This will be rolled back}')", sqlConnection).ExecuteNonQuery();

        transaction.Rollback();

        // Now doing some work with the DB.
        // You might expect it to become a part of transactionScope, but that is NOT the case!
        // So this command will actually succeed, with data written to …
