当使用Entity Framework CTP 5“仅代码”时，如何获得原生SQL基础的LINQ查询？

我在仅代码模式中使用了实体框架CTP5。对于从数据库返回的对象，我正在运行一个LINQ查询，因为查询运行速度非常慢。有什么办法可以得到从查询生成的SQL语句？

I've using Entity Framework CTP5 in "code only" mode. I'm running a LINQ query on a object that was return from the database, as the query is running really slowly. Is there any way in which I can get the SQL statement that is being generated from the query?

Topic currentTopic =
    (from x in Repository.Topics
     let isCurrent = (x.StoppedAt <= x.StartedAt || (x.StartedAt >= currentTopicsStartedAtOrAfter))
     where x.Meeting.Manager.User.Id == user.Id && isCurrent
     orderby x.StartedAt descending
     select x).FirstOrDefault();

Repository属性是DbContext的后代。

The "Repository" property is a descendent of DbContext.

这有点复杂，因为EF不能在对象上使用我的帮助方法，所以我直接在查询中指定逻辑。

It's a little complicated, as EF can't use my helper methods on the objects, so I'm specifying the logic directly in the query.

那么有没有什么办法可以转储由LINQ查询产生的SQL（例如到我的log4net库）？

So, is there any way I can dump the SQL that will be produced by that LINQ query (e.g. to my log4net repository)?
