EF 4.x 和事务

Question

关于以下错误的任何想法：

System.Data.EntityException: An error occurred while starting a transaction on the provider connection. See the inner exception for details. ---> System.ObjectDisposedException: Safe handle has been closed
   at System.Runtime.InteropServices.SafeHandle.DangerousAddRef(Boolean& success)

为了给您一些背景知识，我们在应用程序的这一部分使用纯 ADO.NET（无事务），它运行良好。我们切换到 EF 后，开始收到此错误。我不相信这与 EF 相关，因为它发生在 ADO.NET 事务代码的深处。有什么方法可以禁用 EF 中的事务？

在做了一些研究并查看了反汇编代码后，我发现您无法在 EF 中禁用事务。
