Final Edit: I found a solution to the problem (at the bottom of the question).
I\'ve got an Nunit problem that\'s causing me grief. Edit:
try calling Close on the dbconnection
make sure the sqllite process is terminated
you can see what process has your file locked with the Unlocker (free) utility
this may be a 'known' issue with SqlLite; the forum banter suggests closing the connection and disposing the command, and suggests that this will be fixed in a future version (since this behavior is not consistent with other ADO providers)
