Where is the document/help of [mono.data.sqlite] ?

I use [mono.data.sqlite] long time ago.

I know, the dlls are in this path:
C:|Program Files (x86)|Unity|Editor|Data|Mono|lib|mono|2.0

I also use Reflector tools to see the code.
Most times I use it with no problem. But, I want to know more about it.

So, I search the document in :

http://www.mono-project.com/SQLite#C.23_Example_.281.1_profile_of_the_new_assembly_and_the_old_assembly.29

But I can’t find it.

Take a look at http://system.data.sqlite.org. You will find a documentation there (.chm file at the bottom of page).

I think this is not 100% compatible with the Mono version, but should help you anyway.
