问题
I am suddenly getting the following errors from SQLite after adding a new transaction:
The database file is locked database is locked
Has anyone seen this? I added an update transaction (following some successful selects/inserts). I can't find anything different about this one...

I figured it out. From looking at this [really old] thread on the phxsoftware site, it seems like there can be locking problems if you don't immediately dispose of readers and commands after executing them.
I fixed my problem by making sure to not keep commands or readers around and surrounding them with using statements.
