我正在寻找这个错误根源的描述:"另一个会话正在使用的事务上下文".

我有时会在我的一个单元测试中得到它,所以我不能提供repro代码.但我想知道什么是"按设计"错误的原因.

更新:错误从SQL Server 2008返回为SqlException.我收到错误的地方似乎是单线程的.但是我可能有单元测试交互,因为我得到了错误,一次运行几个测试(VS2008sp1中的MSTest).但失败的测试看起来像:

• 创建一个对象并将其保存在DB-transaction(commit)中
• 创建TransactionScope
• 试图打开连接 - 这里我得到了带有这种堆栈跟踪的SqlException:
