This is a straight port of sqlite-net to unity3d as an installable package.
See https://github.com/praeclarum/sqlite-net for details on that project.
Some examples can be found in the tests folder.
The tagged release version here matches the tagged releases of that project.
This is not a modified version of sqlite-net; you must use the 4.6+ runtime to use it.
For 'safe' use (eg. dealing with reflection in IOT contexts), please use a higher level api wrapper.
From your unity project folder:
npm init
npm install shadowmint/unity-3rdparty-sqlite-net --save
echo Assets/packages >> .gitignore
echo Assets/packages.meta >> .gitignore
The package and all its dependencies will be installed in your Assets/packages folder.
Run npm install in the tests folder to install dependencies.
