How to handle database operations using threadpool and entity framework?

I really need some code examples here... What I am trying to do:

GetCollectionFromDatabase
foreach item
{
    resetEvents[i] = new ManualResetEvent(false);
    var makeRequest = new MakeRequest(resetEvents[i]);

    ThreadPool.QueueUserWorkItem(new WaitCallback(makeRequest.ThreadPoolCallback), i);
}
db.Save();

T开发者_如何学运维hreadPoolCallback    
{
    update/delete the row 
}

Is this the right appoach? Do I pass in the db as a ref to the ThreadPoolCallBack?

You will have to create a context within the thread pool callback. Entity framework contexts are not multi threaded and cannot be shared by different threads.

I take it db is your database context in this case. You will have to create a new one in ThreadPoolCallback and save it there.
