I'm working on a iOS project that needs FTS on a SQLite DB.
I've followed the instructions found on the web concerning the building of a custom version of SQLite, together with a user function to order the results of a FTS by relevance, and built it all with XCode, setting a new Static library target and obtaining a libSQLite.a as output.
On iOS everything works ok! The FTS, the relevance order, etc.
Now there is the need to port everything on MonoTouch. I've followed the instructions to use the libSQLite.a built from XCode in the MonoDevelop project, found at How to use FTS in SQLite with Monotouch for iOS
In particular, I wrote a SQLite wrapper in C# for the library thanks to the tutorial found at http://www.switchonthecode.com/tutorials/csharp-tutorial-writing-a-dotnet-wrapper-for-sqlite
I also changed the references to the .dll with __Internal as the SO Question said, but still I can't understand why it doesn't work.
The application starts and immediately crashes, even if I don't call any method of the SQLite class.
The code just stops at window.MakeKeyAndVisible();
This is the error:

What should I do?
