Re: DeadLock issue in MultiThreading due to foreign key constraint.

That list of about 12 statements are between BEGIN and COMMIT?

Perhaps the DELETE is removing something that the other thread is trying to work with?

LinkedLineItemId is the FOREIGN KEY that is "causing the trouble"? 2646 and 2650 are somehow involved -- Were they inserted during the same transactions?

Guess #1: A logic error in those 12 statements.

Guess #2: The deadlock may be unavoidable. So, the 'fix' is to detect it and restart the transaction. You seem to be detecting it, but I don't notice the restart.
