LinqPad / Sqlite version info and foreign key support

I am using fabulous LinqPad and its Sqlite driver.

1) Is开发者_运维问答 there a way to obtain Sqlite version information by executing say "select version"?

2) Which driver specific connection string should I use to enable foreign key support in Sqlite?

select distinct sqlite_version() from sqlite_master;

---

1) select sqlite_version()

2) on http://sqlite.phxsoftware.com/forums/p/2159/8788.aspx they say the connection string parameter is EnforceFKConstraints, the SQLite documentation isn't as browsable as I would like it to be :/
