Kevin - Is the DB connection still open at the point you call EndExecuteReader()?

InvalidOperation exception

Comment:
I have some code that I was trying to improve by adding the new asynchronous SQL methods Begin... and End.... But when I add it to my code I get an exception:
InvalidOperationException.
{"The asynchronous operation has already completed."}
The first few frames of the stack trace look like:
at System.Data.SqlClient.SqlCommand.VerifyEndExecuteState(DbAsyncResult
dbAsyncResult, String endMethod)
at System.Data.SqlClient.SqlCommand.InternalEndExecuteReader(IAsyncResult
asyncResult, String endMethod)
at System.Data.SqlClient.SqlCommand.EndExecuteReader(IAsyncResult
asyncResult)
In searching the internet I see that at least one other person has seen this problem. I was wondering if there is a work around? If anyone has gotten the asynchronous methods to work without this exception I would very much appreciate their tips. I would also welcome a confirmation message of simply "this is a known bug".
Comments?
Thank you.
